@WillProwse If we wanted to install the 3kw 48v system in an RV, can you please recommend what panels to use, as the guide says do not use 400 watt panels on an RV, so what panels would you recommend then?
That one needs to be built on a furniture dolly or a forklift pallet. These are all incredibly useful for farmers and homesteaders. This is a great way to build an electrical system and still move it as you upgrade your house, barn, everything.
Thanks Will. I actually built the small system you are showing from one of your previous videos. Thanks for updating the information because I was trying to figure out that the strip outlet is only around 1800 watts and the system can push 3000 watts and didn't know how to capture the other wattage. Your update makes perfect since. Thanks again Will. Keep up the great work you do!!!
Hi Will, Long time viewer. Looking at this video and thinking about how far you have come. I wired solar in my RV via your videos and built this exact cart system in my garage that runs 6 circuits in my house. You have given so much to the solar DIY’s. Thanks and keep it up. You and Ilan Musk are my heroes!!!!!
My solar array is 1600watts running 16 x 100 watt renogy panels in series. I run my refrigerator, tv, small window ac and large air fryer on occasion. I have two 24 volt 200ah EG4 batteries in series.
Re: 3kw cart update. Eco worthy has 48v 50AH batteries for $630 - $100 promo. I ordered two for 100AH of capacity for barely over $1000 after tax. Signiture solar is offering a $50 off coupon for new customers. So $1500ish pre tax for eg4 + 5kwhr of capacity. Absolutely smashes prebuilts in terms of cost, capacity, input, output, upgradability, and feature.
YT filters. I can't name the site even. I've posted twice and it keeps vanishing. They are selling them manufacture direct on the large and well known auction site. $563 after $100 off promo. Or $1126 + tax for 2x 48v 50ah batteries.
The site rhymes with "flea bay". I have not opened them up as I'm assuming it's like all other budget lifepo4 units and "good enough". One 48v/50ah battery and eg4 would give you almost the same capacity as an eco flow pro (2500 whr vs 3600) but much more upgradability and almost 1/3rd the cost.
That's crazy... You should show us how to move it up steps LOL. It looks like it almost catapulted you when you stood it back up! People made fun of me for the last one I built - claiming it was too big/heavy. Very cool concept though.
Love the 240v cart idea. It's what I asked for in the other video. You're correct in that a hand truck system is silly. However as a temporary back up. I have a 14-30 twist-lock generator input on the side of my house. Adding the same output to your system, and having on a cart just to move as needed, or a semi permanent system if you will. Thanks so much for all your videos! I've learned so much from them and your website community!
Will, another excellent setup and video. I truly appreciate your knowledge and simplicity in communicating this stuff. FANTASTIC! In your opinion would a system like the 3kw system be overkill, to power a home office consisting of laptops, battery chargers, gaming computer, small work bench using heat gun, charging batteries for battery operated tools, standard home office printer, small set of desktop speaks, and a 35 inch TV (periodically)? Not everything would be running 24/7 and not all at the same time. Thanks much. Great build and update, looking to do the same, and would be using your links. Final note your book is gold! Thank you again, so much.
Will First off Thanks for your efforts; I'm building this system but using a Cosco Cart that goes on sale semi annually at Costco. It lays flat and angles and sells for 100. I have two of them and use them regularly for construction and they hold up great. Lightweight made of aluminum.
Thanks for your video, I made a cart with the EG4 6500EX-48, and EG4 48 volt battery with an additional bay for the another battery. It does the same as yours on a plywood cabinet with large caster wheels. Glad to see the solar plugs on your unit. I could never get a strait answer as to which plug ends for the solar leads. Thanks for the video.
Will, I would love to see you evaluate some solar charge controllers, BMS, inverters and all-in-ones on the basis of how RF quiet they are. Im an amateur radio operator.. One of the big things holding me back from building systems like this is my constant fight to eliminate sources of RF on my property. I Don't want to waste money on something I can't use due to it leaking RF emmissions.
Awesome video as usual, I have learned so much from your videos. I am totally interested in the bigger build as i have tried to imagine a lifestyle where i use my solar farm to charge units like that and transport them to country houses (My dad, grandparents) and swap them out as needed. Using some sort of modular concept for easy unit swaps. Also, using these on a wrecker of sorts to give a discharged electric vehicle a boost out in the wild,
Will! L👀K at you!!! I remember when 🥹 it is so heartwarming to see your channel at almost a milly and you looking so healthy! How I wish you were my neighbor! I want so badly to have a solar backup for my well pump (cuz if electric goes out, no water 🙄) BUT OMG, I get a different suggestion from every single solar guy. I wouldn’t even question what you suggested, OR what you charged! Your brain is better than AI when it comes to solar 🫣 least you’d have my vote! So happy for you!!! ✌🏽💜🦋
*agree with you in using a 4 wheel cart* in 2019 i built one using a 4 wheel cart that a hospital threw away, it had no door bangs here and there, fixed it. i had seen the "4 star rolling thunder power supply" (discontinued) so i went off that, on the side i mounted a Sunpower inverter and put the 48 volt "discover advanced energy lithium ion battery" model # 42-48-6650 at shy of 200 lbs you need 4 wheels with this battery
Hi Will. Great to find your video. Try making as a 2 static wheel + 2 swivel wheels (4 wheels total). Two of the wheels electric, with low rpm (30 Rpm). 2x 150watts motors will be enough
Could you make the smaller system in a 12v portable inside a tuff box...like a pelican case with its own handle, so it could be put under an RV in an outside environment? I wonder where the fan openings would go. I'm curious about the bigger system in a 4-wheel cart configuration, or even a larger system on a lightweight Lowes trailer as an off-grid construction module. Can tax credits be used if hooked to your home, even if in a mobile configuration?
I bought one last Nov. it's on my back porch with 1200 watts of solar and a 5kw server battery on a hand dolly so I can use it at the barn when I need power there. Has continually run my 7 cubic foot freezer outside lights tv and fans without a hiccup.
@dougwilson8274 I was thinking about building one for my shed, to run power tools and such. My biggest concern is safety. Did you ground everything to the dolly, or as Will said in his one video just don't touch both battery terminals?
any reason to not use an EG4-6000ex? 240v, smaller and has much better PV input. That big cart seems clunky and could be improved just by switching to that
Will prowse What do you think of doing a mobile setup with the eg4 6000xp inverter and 1 or 2 server batteries. ? What about mounting the inverter to a 3 rack eg4 box on wheels ? I have a 10kw 120/240 gas generator to plug in for charging as well as grid power to charge when power is up.. What charge and discharge cables would you use ? loads would likely be all 120v
This portable is close to solving a cool problem. Imagine that the inverter was able to generate grid so AC coupled inverters could turn on when the sun is bright. Yes, I would need to manually disconnect the utility but a manual disconnect is so much cheaper than a set of schneider parts. With 30kwhr of battery, it would mean leaving the utility off for most of the year, which is not good for sellback but if they dont pay, why bother. Therefore, my request Will, is to modify and test your test unit. thank you
That 240v system is hilariously awesome... Can't believe you actually made that. Be careful what you ask for people! 🤣 The 3kW cart is looking even better! Way way cool. And thanks for sharing that boost charge controller! Never heard of that before. Could be very useful with this setup for only a few smaller panels since the minimum required PV voltage on the EG4 3000 is pretty high.
@WillProwse I know you like these crazy projects. Here's one for you. 48v Mower charged by solar, but can double as a mobile power station. While its stationary charging, it could power your fridge, or deep freeze. Go.
Think lawn and garden poly dump trailer or similar. A powersupply a bit larger with more capacity than an off-the-shelf mobile power station that can be towed with anything from a simple lawn and garden mower, ATV/RTV, or small tractor. Most homesteads and off-grid cabins already utilize these types of small trailers and machinery. All hardware within the bed of the trailer with a hinged 2x4 top that doubles as a work table top. At some point I am going to build a small towable 120/240 power station that can be easily towed in remote locations. Feel free to beat me to it.
Great job and thank you very much. Just bought my first solar panels set to get them tomorrow. I wonder if you could put two all on ones on the hand truck for split phase ? Maybe some Unistrut across the hand truck top.
Just make 2 of the smaller carts and then make a small box with the wiring to bring together both carts for a 240v system like Eco does. That would open lots of uses for them together or separately. For the Big Foot build, use the Harbor Freight utility cart (1000 lbs. capacity & cheaper) instead of a 2-wheel dolly.
Will, I was curious if you could cover the 3k or a batteryless inverter by eg4 or similar company for doing hot water heating. I have had solar for 8 years and some of the last things to take care of are air conditioning (which you have covered w/ the eg4 hybrid systems) and the need to solve my hot water heating needs. I use propane now and it's expensive seasonally upwards of $4 per gallon now. Being able to stack a few thousand watts of panels with a batteryless inverter to at least one element is what I'm looking for. Not sure if the 3k is in the ballpark to do that or not. Will still have the propane tankless in-line with the electric heater, but hoping to cut down on costs. Last 200 gallon fillup was about $800 bucks and I do this twice a year with 8 in our household. Thanks for the great channel.
thank you Will. thank you for all your videos. i am about to build the diy 48v offgrid from your blueprints with the eg4 6500. it will be here when i get back from rome. so yes take out the grounding screws and just have it grounded at the load panel. this is correct right? just making sure. it will be a floating offgrid. just like yours.
I'm thinking of building a power station cart similar to your smaller 3kw all-in-one inverter system, but on a 4 wheel tool cart, instead of a handtruck. I'll put the EG4 3kw AIO inverter vertical at one end of the cart, and the batteries on the bottom shelf, leaving the top shelf of the cart empty, but my question is can I build it with just one EG4 3kw AIO now and add a 2nd EG4 3kw AIO inverter later for 240V split phase output, but connect both inverters to the same 48V battery bank? I'm using four 12V - 300amp/hour batteries connected in series to get 48 volts, and won't have room for another 4 batteries, and I already have the 12V batteries and can't afford to switch to 48V rack mount batteries.
Interesting as usual... I have watched many videos on RV related lith batteries. WHen my lead acid batts give up. A 200ah lifepo4 will go in place. My controllers are compatible . thanks
Will, just a quick question. When the power comes into the EG4 does it charge the battery and the battery runs the load or does it run the load and then charge the battery at the same time?
Hey Will. Can you show how you could hook up a 120v generator to the 6500ex setup in split phase? Just for backup if a string of cloudy days comes along to help charge batteries.
Hey Will, Would you please create a video regarding safety and efficiency considerations of RV solar panels. Which panels/manufacturers hold up to mobile conditions, hail, wind, vibrations, snow load weight etc. trying to research the most durable framed solar panels but haven’t found useful information.
Impressive Will. How about a 4-wheel wagon style cart with the MPP controller on a folding frame? I do some Solidworks design if you or someone else might be interested in playing around with a design.
Question, in this vid Will shows the EG4 uint (really like it for my RV) and he shows a 48v to 12v step down to power 12v loads. He shows a 12v load panel attached to the 12v side of the step down. For my rv, can I connect the 1v side of the step down directly to my RV 12v load (via a bus bar perhaps)? I really like the idea of the 48v server rack battery, but I was wondering if I can use it to power my 12v loads in my RV. And IF I can do that, do I need to turn off my RV onboard converter/charger?
Instead of making pigtails to interface, Donwhat I did and put an GE RV panel on the system, gives you the options of sockets without the need to change your pigtail.
I'd build a cart like a dolly with some large pneumatic casters. put the batteries on bottom and inverter on top all sitting horizontal. maybe use an old v-belt for a handle to pull it around.
Appreciate how informative you are. You’ve helped me learn so much. Really wish I could find real reviews for NATURE'S GENERATOR POWERHOUSE. It really looks like a contender but literally can’t find any real reviews.
You should make it so the big one is on 2 carts. One with batteries, and one with the innverter... ++ Quick disconnects. How much would the 240v one cost? Total build $$$?
Hey Will, please review the midnight solar Rosie. All the standard test would be great but could you add tests for RFI on Ham radio HF and VHF bands ? I'm sure one of your viewers would jump at the opportunity to bring you a ham radio for the testing
Could you have both a 30 amp plug AND a surge strip on the 3kW? So I could use it for my RV AND portable AC use. How? I'm new here. Wow your videos are top notch.
Will, the Amazon user comments on that 48v-to-12v converter are saying that the instructions are wrong, the yellow/ black are the input (48v) and the red/black are outputs. Someone has a IR photo of it hooked up per the instructions. Just a heads-up. Maybe a few people got bad units??
Can I just confirm it's ok to have the LiFePO battery terminals facing the ceiling? Definitely no drawbacks or effect on life of the battery? Best, Cain
How would I setup 2 of those smaller units to provide Split phase 120/240 like in a regular home so I can have 2pole breakers to run a 240 appliance such as a mini split in an RV
Hopefully you or a subscriber can answer this question, can I add to my off grid two LV6548 inverters, 7 enphase micro inverters to my main off grid electrical panel without hurting my LV6548 inverters??
I wish I understood how to do a solid grid tie system. Still trying to research, and trying to understand my electric companies regulations around solar
I live in an island called st lucia and we got 220v to 240v grid system and would like to see a solar system build to match that grid system and an all in one kit the we can use down here.
So it is possible to hook up the surge strip AND a 30a RV plug to the same output? Would want to use 30a plug while at home but have an option to plug things in with the surge strip if mobile.
Wil, I have a design question for you. I'm in the process of converting my 1998 42' Class A motorhome to lithium and eventually add solar. I've been doing a lot of watching you and others. I started with buying the Trophy cells from overkill you suggested, and I made two 12v 100ah batteries to replace the 4 6v batteries it had that were junk. I also bought the Victron smart shunt and the Victron DC to DC charger. This worked great. Of course, I wanted to go bigger, so when my wife wasn't looking I bought a Victron Multiplus II 2x120 24v version to replace my older charger/ inverter. I also bought the lynx shunt, lynx distributor, and the cerbo gx with the touch screen. I paired this with the EG4 battery 24v 200AH you seem to like. I have the battery mounted under my bed in a configuration that will allow me to buy more in the future and stack them like if the rack had tipped over on its back. In putting this together, I needed a way to convert the 24v down to 12v to run everything in the camper. I read about someone else using an Orion 24/12 70 from Victron. They said you could put more in parallel if you needed more amperage. Like when pulling the large slides in and out. I had an idea, however. I know I could buy a 24v BMS for my trophy cells and add it to the EG4, but that mixes batteries. So, I wondered if it would be worthwhile to use the 12v batteries as an "accumulator" to help absorb large loads? I hooked it up that way yesterday. All the lynx components are 24v. I installed two busbars below them that are 12v. I hooked the Orion between the two, but it doesn't output enough voltage to charge the Trophy batteries. I'm contemplating using the Orion to charge the 2 AGM chassis batteries. I've been trying to keep them separate so that if my coach batteries die, they will not. My thought is that the Orion 24/12 70 will draw from the EG4 to charge the 12v AGM batteries to 13v, which will, in turn, trigger the Orion smart 12/12 30 to charge the Trophy "house" batteries to 14v. If the EG4 shuts off because of low voltage, the AGM batteries will stop charging and eventually drop below... let's say 12.8, which will stop the Orion smart 12/12 30, and finally, the Trophy batteries will deplete themselves... Am I totally wrong in my planning? Does this sound like it will work?
Please do a video explaining ' where the excess PV power goes ' on an off grid system when the battery is fully charged and the PV input power is way larger than the load - I think it is ' throttled ' by the inverter but don't understand how . My setup is 6 panel array producing 2,760 watts --> All in one Kodak ogs 5.6Kva which has a 3.5KVa Pylontech LiFEPO4 battery . So when the load is 270 watts, and the panels are outputting 2300 watts at midday , when is the excess going as it does not seem to be converted to heat . This is not like ' clipping ' where the inverter ensures no overvoltage to the battery . I have searched the internet for months , tried Chat GPT but no one can provide a clear / understandable answer.
I’m new to electrical topics. I’m following everything but the 48V to 12V Converter part. What is the use case here? Without that can I still use the whole system with the typical home appliances?
Is there any reason you couldn’t install this inside a portable rack case (typically used by musicians)? Seems it might be more portable especially for rv use.
Makes me wonder if a more realistic avenue would be to use a centertap transformer from either a single phase 230V or single phase 110V setup to get you your split outputs off a smaller all in one unit. Might have some issues with your false neutral in such a setup depending on inverter though. Things that make you go hmmmm. Certainly at least easier for us in europe just being single 230 across entire home anyway.
I had that thought myself. I can run my Miller 210 MIG off my 6KW gas generator welding 1/4" steel. This would be perfect with an inverter machine like a 211.
I have a video idea for you I just purchased a EG4 3kw off-grid all-in-one inverter and I purchased a Vatrer 51.2v 100ah battery server rack battery to put on a dolly can you do a video on how to set up the menu with a battery with no Communications that would be greatly appreciated
These “mobile” builds are awesome in the sense that I’d love to build them and use them, but if I tried to wheel one of these into our campsite my wife is gonna think I’m drunk and delusional. I’ll drag the EcoFlow to preserve some of my pride lol
I was thinking about running a second alternator on my skoolie for the house batteries.. I removed the bus air conditioners and have two pulleys with nothing to pull.. someone told me that it wasn't a good idea. What do you think?
Can you do a video on a battery DIY expansion for the Delta Pro? I started my project I bought a utility cart and buying everything one part at a time. My plan is to feed the battery into the solar input of the delta pro. Right now I have a smart plug that cuts off at sun down. I have a circuit breaker connected to the battery. I flip the breaker and it feeds the 100W into the solar input on the delta pro. It bumps it up a bit and adds a few hours of run time. BUT my NOCO GEB 5X3 cant recharge the 12V battery fast enough. A work in progress. Any ideas to make this better?
It would be ok to put in a van and go out on the road to recharge people who had run out of power or didn't make it to a charging station. A mobile charging station on wheels. What if you mounted one of the batteries on the back side. That would make the weight closer to center line and easier to tip back. Get a hand truck with vertical handle system.
Hey Will while you are churning out videos how about one to review different panel set ups you might use with the mobile generator, can you do something that talks or demos connecting 5 175 w panels or 4 400W panels, are they series or parallel strings etc. what options and what you recommend for the 3k system?
I've heard that you can build a parallel and series battery circuit but have never seen a video on such. For example, take two batteries and parallel them and hook them up to two batteries in series. I believe that would increase both voltage and amps at the same time. If so, can you make a video of the advantages and disadvantages? Thank you!
The EG4 6k 120/240 AIO would be a better base. I built one into our 48v golf cart with 2 EG4 WP batteries to be a mobile power station a 330w panel on top with a Gensun SSc and pulling a small trailer with 3 hard mounted 330w panels, one fixed flat and two hinged on the sides and 3 more slid into racks which can be deployed when you arrive on site…
That large one is a bit too much lol. I think multiple smaller carts would be great for a construction site. It took us a long time to get the generator and all the extension cords ready, and then put away again at the end of the day. Each person could move a cart around with them, and then return it to the charging station when done.

Hmm. Comment didn't post. I haven't heard of RF issues on GroWatts (or others).
Awesome video as usual, I have learned so much from your videos. I am totally interested in the bigger build as i have tried to imagine a lifestyle where i use my solar farm to charge units like that and transport them to country houses (My dad, grandparents) and swap them out as needed. Using some sort of modular concept for easy unit swaps. Also, using these on a wrecker of sorts to give a discharged electric vehicle a boost out in the wild,
Will! L👀K at you!!! I remember when 🥹 it is so heartwarming to see your channel at almost a milly and you looking so healthy! How I wish you were my neighbor! I want so badly to have a solar backup for my well pump (cuz if electric goes out, no water 🙄) BUT OMG, I get a different suggestion from every single solar guy. I wouldn’t even question what you suggested, OR what you charged! Your brain is better than AI when it comes to solar 🫣 least you’d have my vote! So happy for you!!! ✌🏽💜🦋
Aww your comment made my day 🥰🥰
The EG4 6kw low frequency split phase unit would seem to be a good match as well.
But then everyone would say Will is just a shill for Signature Solar 😎
@Joe H
Some people already do. But he honestly rags on their faults as much as any others.
*agree with you in using a 4 wheel cart*
in 2019 i built one using a 4 wheel cart that a hospital threw away, it had no door bangs here and there, fixed it.
i had seen the "4 star rolling thunder power supply" (discontinued) so i went off that, on the side i mounted a Sunpower inverter and put the 48 volt "discover advanced energy lithium ion battery" model # 42-48-6650 at shy of 200 lbs you need 4 wheels with this battery
Hi Will. Great to find your video. Try making as a 2 static wheel + 2 swivel wheels (4 wheels total). Two of the wheels electric, with low rpm (30 Rpm). 2x 150watts motors will be enough
Could you make the smaller system in a 12v portable inside a tuff box...like a pelican case with its own handle, so it could be put under an RV in an outside environment? I wonder where the fan openings would go. I'm curious about the bigger system in a 4-wheel cart configuration, or even a larger system on a lightweight Lowes trailer as an off-grid construction module. Can tax credits be used if hooked to your home, even if in a mobile configuration?
Seriously considering getting one of these EG4 3K units! Please keep us updated on the reliability of this unit!
I bought one last Nov. it's on my back porch with 1200 watts of solar and a 5kw server battery on a hand dolly so I can use it at the barn when I need power there. Has continually run my 7 cubic foot freezer outside lights tv and fans without a hiccup.
@dougwilson8274 I was thinking about building one for my shed, to run power tools and such. My biggest concern is safety. Did you ground everything to the dolly, or as Will said in his one video just don't touch both battery terminals?
Thanks i had a take it a fishing hunting cabin and running ac kind of thing in mind great work
Now that's a good build both are great thanks for sharing this six stars
any reason to not use an EG4-6000ex? 240v, smaller and has much better PV input. That big cart seems clunky and could be improved just by switching to that
Will prowse What do you think of doing a mobile setup with the eg4 6000xp inverter and 1 or 2 server batteries. ? What about mounting the inverter to a 3 rack eg4 box on wheels ? I have a 10kw 120/240 gas generator to plug in for charging as well as grid power to charge when power is up.. What charge and discharge cables would you use ? loads would likely be all 120v
This portable is close to solving a cool problem. Imagine that the inverter was able to generate grid so AC coupled inverters could turn on when the sun is bright. Yes, I would need to manually disconnect the utility but a manual disconnect is so much cheaper than a set of schneider parts. With 30kwhr of battery, it would mean leaving the utility off for most of the year, which is not good for sellback but if they dont pay, why bother. Therefore, my request Will, is to modify and test your test unit. thank you
I have to go to your book all the time . Invaluable any time I work with inverters . Gonna look at paneling
And probably eliminate lots of cash loss and 'Will be Happy 😁 that way . Thanks Mon
T/C/E
check the forum. The book is out of date. Yes, some things in it are true, but there's been many solid advancements since then.
That 240v system is hilariously awesome... Can't believe you actually made that. Be careful what you ask for people! 🤣
The 3kW cart is looking even better! Way way cool. And thanks for sharing that boost charge controller! Never heard of that before. Could be very useful with this setup for only a few smaller panels since the minimum required PV voltage on the EG4 3000 is pretty high.
@WillProwse I know you like these crazy projects. Here's one for you. 48v Mower charged by solar, but can double as a mobile power station. While its stationary charging, it could power your fridge, or deep freeze. Go.
Think lawn and garden poly dump trailer or similar. A powersupply a bit larger with more capacity than an off-the-shelf mobile power station that can be towed with anything from a simple lawn and garden mower, ATV/RTV, or small tractor. Most homesteads and off-grid cabins already utilize these types of small trailers and machinery. All hardware within the bed of the trailer with a hinged 2x4 top that doubles as a work table top. At some point I am going to build a small towable 120/240 power station that can be easily towed in remote locations. Feel free to beat me to it.
Sounds like the better option is 2 of your original power dollys and run them in parallel for 240?
Takeing an electric dirt bike to the trails and haveing 240v charging would be so cool!! Could even do a PV sun canopy for the camp spot!
Total beginner here: so this 3kW system is split phase, allowing me to power 240v devices? Your channel and input is great. Thanks.
Great job and thank you very much. Just bought my first solar panels set to get them tomorrow. I wonder if you could put two all on ones on the hand truck for split phase ? Maybe some
Unistrut across the hand truck top.
Just make 2 of the smaller carts and then make a small box with the wiring to bring together both carts for a 240v system like Eco does. That would open lots of uses for them together or separately. For the Big Foot build, use the Harbor Freight utility cart (1000 lbs. capacity & cheaper) instead of a 2-wheel dolly.
Will, I was curious if you could cover the 3k or a batteryless inverter by eg4 or similar company for doing hot water heating. I have had solar for 8 years and some of the last things to take care of are air conditioning (which you have covered w/ the eg4 hybrid systems) and the need to solve my hot water heating needs. I use propane now and it's expensive seasonally upwards of $4 per gallon now. Being able to stack a few thousand watts of panels with a batteryless inverter to at least one element is what I'm looking for. Not sure if the 3k is in the ballpark to do that or not. Will still have the propane tankless in-line with the electric heater, but hoping to cut down on costs. Last 200 gallon fillup was about $800 bucks and I do this twice a year with 8 in our household. Thanks for the great channel.
thank you Will. thank you for all your videos. i am about to build the diy 48v offgrid from your blueprints with the eg4 6500. it will be here when i get back from rome. so yes take out the grounding screws and just have it grounded at the load panel. this is correct right? just making sure. it will be a floating offgrid. just like yours.
Will, Could you please point me to the proper 400 watt panels to run this system? Thanks for sharing your skills and knowledge.
EG4 18K self contained on a contractor cart? 4-6/400AH Server Rack Batteries and a 18K?
I'm thinking of building a power station cart similar to your smaller 3kw all-in-one inverter system, but on a 4 wheel tool cart, instead of a handtruck. I'll put the EG4 3kw AIO inverter vertical at one end of the cart, and the batteries on the bottom shelf, leaving the top shelf of the cart empty, but my question is can I build it with just one EG4 3kw AIO now and add a 2nd EG4 3kw AIO inverter later for 240V split phase output, but connect both inverters to the same 48V battery bank? I'm using four 12V - 300amp/hour batteries connected in series to get 48 volts, and won't have room for another 4 batteries, and I already have the 12V batteries and can't afford to switch to 48V rack mount batteries.
Interesting as usual... I have watched many videos on RV related lith batteries. WHen my lead acid batts give up. A 200ah lifepo4 will go in place. My controllers are compatible . thanks
Will, just a quick question. When the power comes into the EG4 does it charge the battery and the battery runs the load or does it run the load and then charge the battery at the same time?
Additional Battery Pack cart and good quick connector setup would be interesting as well ;)
Great video, Thanks for sharing your knowledge
Hey Will. Can you show how you could hook up a 120v generator to the 6500ex setup in split phase? Just for backup if a string of cloudy days comes along to help charge batteries.
Hey Will, Would you please create a video regarding safety and efficiency considerations of RV solar panels. Which panels/manufacturers hold up to mobile conditions, hail, wind, vibrations, snow load weight etc.
trying to research the most durable framed solar panels but haven’t found useful information.
Impressive Will. How about a 4-wheel wagon style cart with the MPP controller on a folding frame? I do some Solidworks design if you or someone else might be interested in playing around with a design.
Just need a welder; move the axle on a cart so it still is handy like a hand truck but has the capacity of the cart.
Question, in this vid Will shows the EG4 uint (really like it for my RV) and he shows a 48v to 12v step down to power 12v loads. He shows a 12v load panel attached to the 12v side of the step down. For my rv, can I connect the 1v side of the step down directly to my RV 12v load (via a bus bar perhaps)? I really like the idea of the 48v server rack battery, but I was wondering if I can use it to power my 12v loads in my RV. And IF I can do that, do I need to turn off my RV onboard converter/charger?
Instead of making pigtails to interface, Donwhat I did and put an GE RV panel on the system, gives you the options of sockets without the need to change your pigtail.
I'd build a cart like a dolly with some large pneumatic casters. put the batteries on bottom and inverter on top all sitting horizontal. maybe use an old v-belt for a handle to pull it around.
Appreciate how informative you are. You’ve helped me learn so much. Really wish I could find real reviews for NATURE'S GENERATOR
POWERHOUSE. It really looks like a contender but literally can’t find any real reviews.
You should make it so the big one is on 2 carts. One with batteries, and one with the innverter... ++ Quick disconnects.
How much would the 240v one cost? Total build $$$?
Hey Will, please review the midnight solar Rosie. All the standard test would be great but could you add tests for RFI on Ham radio HF and VHF bands ? I'm sure one of your viewers would jump at the opportunity to bring you a ham radio for the testing
Wouldn’t it be nice to be able to access plans online for the 3kw small power cart.
WOW!! that's a Monster!
Could you have both a 30 amp plug AND a surge strip on the 3kW? So I could use it for my RV AND portable AC use. How? I'm new here. Wow your videos are top notch.
yo will it might be a great idea to add 2 heavy duty caster to the front of your yellow dolly for better mobility.
Will, the Amazon user comments on that 48v-to-12v converter are saying that the instructions are wrong, the yellow/ black are the input (48v) and the red/black are outputs. Someone has a IR photo of it hooked up per the instructions. Just a heads-up. Maybe a few people got bad units??
Weird. Mine works great. I thought the wiring was correct on mine
Can you please put the settings that need changed for the 3k inverter build in the description
Upgradeable hand cart. Lv2424+eg4 24v. Double both for 240v and capacity. Might be tricky to mount a second battery tho
Can I just confirm it's ok to have the LiFePO battery terminals facing the ceiling? Definitely no drawbacks or effect on life of the battery?
Best,
Cain
How would I setup 2 of those smaller units to provide Split phase 120/240 like in a regular home so I can have 2pole breakers to run a 240 appliance such as a mini split in an RV
Hopefully you or a subscriber can answer this question, can I add to my off grid two LV6548 inverters, 7 enphase micro inverters to my main off grid electrical panel without hurting my LV6548 inverters??
I wish I understood how to do a solid grid tie system. Still trying to research, and trying to understand my electric companies regulations around solar
Is there a step by step on how to setup. And how to setup or if 8 100watt solar panels will work best series or parallel? Thank you ahead of time.
I live in an island called st lucia and we got 220v to 240v grid system and would like to see a solar system build to match that grid system and an all in one kit the we can use down here.
Hey Will, would you be able to just add a Step Up Transformer to the smaller cart to run 240v loads?
So it is possible to hook up the surge strip AND a 30a RV plug to the same output? Would want to use 30a plug while at home but have an option to plug things in with the surge strip if mobile.
Wil, I have a design question for you. I'm in the process of converting my 1998 42' Class A motorhome to lithium and eventually add solar. I've been doing a lot of watching you and others. I started with buying the Trophy cells from overkill you suggested, and I made two 12v 100ah batteries to replace the 4 6v batteries it had that were junk. I also bought the Victron smart shunt and the Victron DC to DC charger. This worked great.
Of course, I wanted to go bigger, so when my wife wasn't looking I bought a Victron Multiplus II 2x120 24v version to replace my older charger/ inverter. I also bought the lynx shunt, lynx distributor, and the cerbo gx with the touch screen. I paired this with the EG4 battery 24v 200AH you seem to like. I have the battery mounted under my bed in a configuration that will allow me to buy more in the future and stack them like if the rack had tipped over on its back.
In putting this together, I needed a way to convert the 24v down to 12v to run everything in the camper. I read about someone else using an Orion 24/12 70 from Victron. They said you could put more in parallel if you needed more amperage. Like when pulling the large slides in and out.
I had an idea, however. I know I could buy a 24v BMS for my trophy cells and add it to the EG4, but that mixes batteries. So, I wondered if it would be worthwhile to use the 12v batteries as an "accumulator" to help absorb large loads?
I hooked it up that way yesterday. All the lynx components are 24v. I installed two busbars below them that are 12v. I hooked the Orion between the two, but it doesn't output enough voltage to charge the Trophy batteries.
I'm contemplating using the Orion to charge the 2 AGM chassis batteries. I've been trying to keep them separate so that if my coach batteries die, they will not.
My thought is that the Orion 24/12 70 will draw from the EG4 to charge the 12v AGM batteries to 13v, which will, in turn, trigger the Orion smart 12/12 30 to charge the Trophy "house" batteries to 14v.
If the EG4 shuts off because of low voltage, the AGM batteries will stop charging and eventually drop below... let's say 12.8, which will stop the Orion smart 12/12 30, and finally, the Trophy batteries will deplete themselves...
Am I totally wrong in my planning?
Does this sound like it will work?
Please do a video explaining ' where the excess PV power goes ' on an off grid system when the battery is fully charged and the PV input power is way larger than the load - I think it is ' throttled ' by the inverter but don't understand how . My setup is 6 panel array producing 2,760 watts --> All in one Kodak ogs 5.6Kva which has a 3.5KVa Pylontech LiFEPO4 battery . So when the load is 270 watts, and the panels are outputting 2300 watts at midday , when is the excess going as it does not seem to be converted to heat . This is not like ' clipping ' where the inverter ensures no overvoltage to the battery . I have searched the internet for months , tried Chat GPT but no one can provide a clear / understandable answer.
Add one battery of the two on the back side of the hand truck for better balance.
Ooohh…interesting!
I’m new to electrical topics. I’m following everything but the 48V to 12V Converter part. What is the use case here?
Without that can I still use the whole system with the typical home appliances?
Is there any reason you couldn’t install this inside a portable rack case (typically used by musicians)? Seems it might be more portable especially for rv use.
Makes me wonder if a more realistic avenue would be to use a centertap transformer from either a single phase 230V or single phase 110V setup to get you your split outputs off a smaller all in one unit. Might have some issues with your false neutral in such a setup depending on inverter though. Things that make you go hmmmm.
Certainly at least easier for us in europe just being single 230 across entire home anyway.
I can see this being useful for mobile welding to replace large gas generators...
I had that thought myself. I can run my Miller 210 MIG off my 6KW gas generator welding 1/4" steel. This would be perfect with an inverter machine like a 211.
I have a video idea for you I just purchased a EG4 3kw off-grid all-in-one inverter and I purchased a Vatrer 51.2v 100ah battery server rack battery to put on a dolly can you do a video on how to set up the menu with a battery with no Communications that would be greatly appreciated
I'm debating on solar or NOT for 28' RV remodel. Only 1-2 adults in the RV. Please advise 🙏
These “mobile” builds are awesome in the sense that I’d love to build them and use them, but if I tried to wheel one of these into our campsite my wife is gonna think I’m drunk and delusional.
I’ll drag the EcoFlow to preserve some of my pride lol
😂😂
I was thinking about running a second alternator on my skoolie for the house batteries.. I removed the bus air conditioners and have two pulleys with nothing to pull.. someone told me that it wasn't a good idea.
What do you think?
Can you do a comparison or chat through a Tesla Powerwall versus one of your homemade set ups/ systems?
Why not just use a Growatt 5000ES and a single battery for 240v EV charging? Add a Zencar adjustable EVSE and charge at 16amps and 240v.
Can you do a video on a battery DIY expansion for the Delta Pro? I started my project I bought a utility cart and buying everything one part at a time. My plan is to feed the battery into the solar input of the delta pro. Right now I have a smart plug that cuts off at sun down. I have a circuit breaker connected to the battery. I flip the breaker and it feeds the 100W into the solar input on the delta pro. It bumps it up a bit and adds a few hours of run time. BUT my NOCO GEB 5X3 cant recharge the 12V battery fast enough. A work in progress. Any ideas to make this better?
It would be ok to put in a van and go out on the road to recharge people who had run out of power or didn't make it to a charging station. A mobile charging station on wheels. What if you mounted one of the batteries on the back side. That would make the weight closer to center line and easier to tip back. Get a hand truck with vertical handle system.
Hey Will while you are churning out videos how about one to review different panel set ups you might use with the mobile generator, can you do something that talks or demos connecting 5 175 w panels or 4 400W panels, are they series or parallel strings etc. what options and what you recommend for the 3k system?
I've heard that you can build a parallel and series battery circuit but have never seen a video on such. For example, take two batteries and parallel them and hook them up to two batteries in series. I believe that would increase both voltage and amps at the same time. If so, can you make a video of the advantages and disadvantages?
Thank you!
What is the stand by power konsumption of the 3KW Red Hand Truk System??
try concentrated photovoltaic solar, ie concentrator parabolic mirror with small solar target
The EG4 6k 120/240 AIO would be a better base.
I built one into our 48v golf cart with 2 EG4 WP batteries to be a mobile power station a 330w panel on top with a Gensun SSc and pulling a small trailer with 3 hard mounted 330w panels, one fixed flat and two hinged on the sides and 3 more slid into racks which can be deployed when you arrive on site…
Reason I didn't use mine is that thing is even heavier! And I just love the 6048 more in general. Better mounting system as well
That large one is a bit too much lol. I think multiple smaller carts would be great for a construction site. It took us a long time to get the generator and all the extension cords ready, and then put away again at the end of the day. Each person could move a cart around with them, and then return it to the charging station when done.
