You could re do this rest with the new sinwave inverter an meter you have ? An the setting you can change this time too. Just a suggestion. I think it be interesting to see the difference.
That's pretty cool. Should definitely determine what you need to keep powered, and test out how long your system can power them. Can always buy some additional portable solar panels and/or a small gas/propane generator to buy some more time.
That's a great suggestion! It's always important to test out your power needs and see how long your system can handle them. The Segway Portable PowerStation Cube Series is a fantastic choice for outdoor enthusiasts like us. With its massive capacity, powerful output, and fast recharging, it's perfect for powering appliances and devices during camping trips or power outages. Plus, its waterproof technology ensures durability in any weather condition. You can also easily monitor and manage power flow through the smart app control. Happy camping!
Solar power is amazing! No power bills for 3 years now. Thanks for the video as I'm contemplating adding a freezer to our appliance fleet
It would be nice to try it with solar to see what you get it. I myself am running just a 3 kW 24v battery and a 1500 W inverter to run another refrigerator. The only thing missing from my equation is a shunt, which I plan to put on today. This way I can monitor the power going in and out of my battery and get a much better picture of the SOC.
I’m only using 600 W of solar, which I don’t think will be enough in the winter.
How many Watt hours are your batteries? I recently did this test with solar in my last video.
@@diySolarPowerFunWithRay
On the data sheet of the Mule big battery 24 V 3 kW it says 120 amp hours. That seems kind of low to me?
@Simon OK so each battery is right around 3 kwh. So 9 KWH total. That almost double the capacity of my 5.120 kwh battery. If you look at my last video I have a bunch of data from my shunt that might give you an idea of how long you can last with you solar connected. I bet you can run 2 fridges for 3 - 4 days with heavy cloud cover.... or forever if you have sun.
@@diySolarPowerFunWithRay
So I believe 3000×24 gives you 7200 W hours?
@Simon to calculate watt-hours you basically calculate the V of the battery X the amp hours. So if you have 24 volt battery.. it should have a nominal operating voltage of higher than that. So let' s just say 25 V. So 25 times 120 amp hours will give you 3 kwh for each of your batteries. (Fixed my typo on my last post)
I'm shocked you got that much run time. It's pretty good actually. Just get one more battery and solar and you will be doing pretty well.
I saw a video, they put a fridge on aa timer to only run 15 minutes an hour, significantly longer run time, and only affected temps 1-2*
Easier solution is to just adjust the fridge to a warmer temperature, I have never seen a fridge where you could not adjust them warmer / colder...
I'm curious if that will put more stress on the compressor, instead of just turning down and let it cycle when needs to.
Hi! What ended up being the issue with your furnace in the video? I want to do a set up like this as my furnace and fridge are the two things that the most consistent draw at home.
Cool test! I did an energy audit on my home fridge and it came out to 120 watts per hour over a couple of days average. So to keep it going on solar I know I will need about 3kwh of solar per day so my battery doesn't drain. Since I have a perfect place for solar in my backyard with very little morning shade and the rest is clear, I would need a peak output of about 600 watts solar input to reach my power goal. Since most solar panels don't output name plate power in normal conditions I will take the 600 watt solar peak and multiply it by 1.4 times which equals about 840 watts of name plate solar panel rating to reach my goal. If you are doing 3 fridges I think you will want 840 watts of solar times 3 which is a very big solar array. The other thing to realize is during a power outage the freezer stays wonderfully cool all day because of all the frozen food so in a pinch you could put some extra water bottles in the freezer so when a power outage occurs you can quickly take the frozen water bottles out of the freezer and put then in the fridge so the fridge stays cool too!
Thank for the numbers, 120 Seems right to me as well. I need to do any audit as well on my critical appliances. I think that's definitely the best way. Those number look good to me.
I do my calculation like this:
In utah, in the winter, I get around 5 peak solar hours per day. With 1000 watts of solar at 75% efficency I should be getting 1000w * 5h * 0.75 = 3750wh. Enough for 1 fridge but not enough for 3.
Good idea with the frozen water jugs! I should put some of those in my deep freezer for sure.
That
You run your refrigerator on an off every 3 hours you can extend your battery run time. They are very well insulated.
That's a good point. That sounds like a good test.
@@diySolarPowerFunWithRay I have an Ecoflow Detla, I run for emergency use only, cable tv and refrigerator, worked flawless when I went 4 days with out power. I even have some solar light bulbs that work good. However down the road I plan on going to a full battery setup, now that they have all in one units.
I do that with a generator. I run it 15 to 20 minutes every 4 hours when we have 5 day (or longer) power outages..
I am also glad I stress tested my smaller Emr setup, you wont know you forgot something until its too late, trying to cob something together under stress is never a good idea!
there were things I forgot like plugs and extra wire in case I need to Cob something after the SHTF LOL
I am in NY so at a deeper angle, panels run 3S3P, dont cheap out on the charge controller and I have just been running a 1500W inverter and even tested a few smaller one, I might get a few more panels and a few more batteries, I can run a lot of stuff for 8 hours and the panels I have now bring up 500 amp hour batteries by 9:30am
my average Ele bill is $550 so even if I spend another $1500 it will pay for it self in a few months! and only use the ele company as my back up LOL
If I was just running the lights and computers in my house I could run for 2 days without sun, and the only thing that takes a lot of power is the icebox ....
This is an awesome test, I plan on doing something similar, thank you much!
Furnace problem is probably a lack of ground-neutral bond
Yup. That was it. Thanks.
@@diySolarPowerFunWithRayhow would you rectify that problem?
I can used one of these plugs in an emergency: th-cam.com/video/wGZeAqnuhaA/w-d-xo.htmlsi=xz3ofEyE7Fti7D0D
So I could run a house furnace off 2 of those batteries?!
I can run two furnaces with just one battery. Two batteries would be better though
Thanks for sharing this, my friend, I plan on doing something similar for my house
@ScottieBMan It's really fun. Do you know what type of inverter and Battery you're planning on getting?
What ended up being the problem with your furnace in the video? I am thinking about doing something very similar!
I'm huge Flintstone Fan. At at the end of the video I swear sir you really look like Fred Flintstone. New subscriber from Cameroon.
Lol! That's funny :)
Great test and I didn’t want to say For everyone talking about don’t run your battery down to 0% actually you can’t the BMS will shut off before any Damage could be done from batteries going to absolute zero now there is 0% usable power so that’s not something to to worry about unless you’re using a homemade battery without a proper BMS.
Thank you for commenting and clarifying. How much better explanation than what I said
So much power loss with those extensions cables.
I installed the EXACT same setup with growatt and EG4 rack battery except i used the 24v inside my friends mobile massage van. 4 120v outlets in the floor and she hasn’t had any problems. She doesn’t have solar but i did hook it up to the alternator of the van, not a whole lot of power but it charges enough for her usage. I also installed a 30a shore power hookup incase she wanted to take it on vacation or something.
Barely any programming required too which was great! Nice video, glad to see someone else doing the same setup
That's nice. Do you remember what you used to hook up the alternator to the batteries?
@@diySolarPowerFunWithRay it was tricky but the van had 3 separate 12v batteries. One for the bus door, one for the motorized ramp, one for lighting through the bus prior to installation. I used a “Stinger” brand isolator off of the door battery, since it was the closest, hooked to a Victron Bluetooth 12/24 dc-dc. Doesn’t give too many watts due to conversions but she hasn’t had any issues. I’m sure i could use 2 or 3 Victrons but then the cost just goes up for 2-3 off the same product. Probably wear out the alternator too.
About 2 hours lol lol lol
you promised in the linking video to show how to sell electricity to grid
I'm still working on that video. My latest build has my house off grid but I am still working on the permits
Furnace computers are really fussy
I know this is a old video but thought I would throw in something. On the fridge freezer in basement if you fill it with solids like jugs of water it will run less. A lot less!. solids hold cold better than air. A empty freezer especially will run more often.
i had no luck i had to get 3
I have just started my 48 volt system. I ran a 24 volt for a year and ran the Fridge and dishwasher. I have to wait until the distribution block come in to wire up the (2) 24volt 300 AM batteries to be 48 volt and I have 3 sets of them so it will be interesting to see how it fairs with the fridge and freezer and the dishwasher.
You asked what you should try next. Well, let say the Sun goes down at 6 pm and returns at 10 am (that is too long of a time for solar panels to be any help). It seems that you need to purchase a second battery, and then I would say to get two 500-watt solar panels, but since you can charge the batteries from the grid (assuming the grid is not off for very long time), that would not be necessary. You could also purchase a Victron 48/1200 inverter (I got one), which has a very low stand-by power consumption, but I recommend investing that money towards a third battery and stay with your existing all-in-one unit.
Cool. Thanks. Yeah, for emergency I think I'll definitely need another battery. I'm thinking over a couple different types solar backup setups for my house. I will post those and be building pretty soon. Thanks for posting...
This winter we had cloud cover for pretty much two straight weeks. If the power went out during that time I would be totally hosed. I'm not sure what to do about that scenario. I don't want to get a generator. I was recently looking at 48 volt 100-amp alternators you can hook in your truck. That might not be a bad option as backup power. My diesel truck could idle for a long time
10 am to 6 pm is plenty of time for the solar to help. Should get at least 3.6 kw of solar for your inverter, with the solar your runtime will increase significantly as your battery will get some charge as well as your home loads without using to much battery.
@slipperyslope5364 yeah I am waiting on delivery of my system. All in one with 8 410w panels and 2 48v 5.12Wh batteries. This should last a couple days with no sun in my travel trailer.
@@johnstark4723 It will last longer than that as each morning with the sunrise your batteries should recharge by noon day or somewhere around there. The cycle should repeat itself daily. Might have to manage your energy usage on excessively cloudy consecutive days. I intend to watch your progress as you post . Cheers
Shocking results. I do this daily with 2 of those batteries and no PV. Just the lights, TV and Refrigerator consume the 10,100 watt hours in about 30 hours. I recharge the batteries daily for ~2 hours with my generator and 75A dedicated charger. Plan to add 4 more batteries an 10kW or PV when I get the funds.
Interesting. How many fridges and freezers are you running? Do your batteries run down to zero or down to the 20% mark
Just the one frig/freezer. Just down to 25% daily.
I think a test that says it all is further down in the comment respond, a 1500 watt space heater full blast pushing out 5120 btu's a little under 3hrs on this system would be a good starting point to build upon.
You need a pure sine wave inverter to run the furnace.
Yes, I would use one of those for sure. There are fragile electronics and you might damage something otherwise. Imo.
Great test! Question: I have a solar array that consists of 4 12volt (200w Rich Solar Panels). I currently have them setup in a series configuration. Would this solar array effectively charge up this setup? Thanks for sharing.
Yes, absolutely. As long as you purchase the same inverter model I use in this video. I have a link in the description. If you use the link to help the channel.
There is another model that I use in other videos that requires a higher voltage which wouldn't work.
Thank you for taking the time to do this experiment. how incredible is to have all those watts from that small batery. we will see 120V bateries with 500Ah soon
The starting voltage and amps for those furnaces is higher than the operating voltage/ amps.
Taught the furnace would pull more current that amazing for one. Battery
This is excellent a excellent test thanks for much for this information
Thank you!
You need 4 and don’t go below 20%
I think you might be confusing these batteries with lithium ion. These lithium iron batteries can go to zero
As real world as it could get. Thanks.
5.1kw Battery 😮 holy Heck
You shouldn't leave a frige or freezer completely empty. When not being used but plugged in,, put a jug of water in them...
Thanks, I didn't know that.
I doubt you can run water heater, microwave, fridges with such 4800Wh battery for 12hour. But its your system, so it is what it is
Yeah, I definitely can't run them for that long. But it is able to run the electric fridge, microwave and then it still has enough power to kick on the AC with out a soft start...( I need to use the eg4 v2 battery though)
So to just run my frig. (like yours) and my laptop/internet, this battery would be enough?
Yup
Good test! Thanks for sharing.
Thank you for sharing with us, pls can i use Growatt 5000es inverter on this battery?
Yes.
Hey was wondering if you had an email I could ask a few questions and get your input on . Great videos btw
Yup, it's in the description.
Just curious.... at the 2:46 mark, where did you get that yellow 30 amp to three 15 amp adapter from?

Checked out this video after my other comment , interesting. How much of a draw does the GroWatt pull from the battery?
From my own testing...If the inverter is idling: 45 Watts. If it's charging the battery from the inverter with inverter off: 15 watts.
Some furnaces require a grounding bond to operate
Thanks I'm still troubleshooting it. I think I have a bond or to take my polarity might be reversed
@@diySolarPowerFunWithRay which growatt are you using? The 145v solar input version or the 250v solar input version? Did you have any trouble setting up the Wi-Fi or battery communications?
@@leafnutz2341 I'm using the 48 volt p. It is the 145 model. I didn't hook up the Wi-Fi dongle but I was able to hook the BMS communication cable up and it works fine. It really only tells you what the battery percentage is though. At least that's the main thing I have noticed with the communication cable
Some other video I watched about the furnace says it's a neutral bonding issue. It's not seeing ground and neutral tied together.
@John Hovan yup. That was the issue. I bonded them, and it works.
Pretty impressive. Thanks for the video.
Thanks!
Could two of those battery supply your house?
For a little bit... But you couldn't power your Air conditioning and other high energy appliances very long.
Looking At the EG4 6000xp, and the batteries that you are using. I just don’t know which way to go with solar panels. What are your thoughts? I’m still really new to this
I would look at getting some used ones possibly from San Tan solar. But if you're already ordering a bunch of items from signature solar you may just want to buy the solar panels from them because shipping might be cheaper as you are already paying to ship the inverter. Are you putting the panels in a ground array or on a garage? Also, what do you plan on powering with your inverter? The eg4 6000 would be Overkill just to run a furnace fan, but it would be nice to have the extra power if you ever need it in the future.
@@diySolarPowerFunWithRay
I’m going for a ground mount, probably my furnace fan, sump pump, refrigerator, a room or two in the house down the road. I plan on expanding down the road so
I like the used panels. I just ordered a pallet of these 325 watt panels and plan on selling the extra ones I don't uses: www.santansolar.com/product/used-jinko-325w-solar-panels-pallet-of-25/?ref=DiySolarPowerFun
Do you have to go into settings to show the battery percentage? Also does your solar unit fan kick in when you the fridge compressor runs?
I can't recall if the fan turned on. It may have turned on low. In order for me to see the exact battery percentages, I need to use the communication cable that came with the battery(th-cam.com/users/shortsjrUVvyzVflA)
@@diySolarPowerFunWithRay Ok thank you:)
Dang man, love your contents
Thanks :)
Good video.
What is the load if all 3 kick in at the same time, would it overload the inverter?
Thanks for the question. After a quick search, apparently inefficient fridges will use 500 watts when they're running.. So that would only add up to 1500 watts. This unit can power 3000 Watts, so it should be able to handle that fine. Are you referring to in Rush current? I'm not sure what that is but in Rush lasts in the milliseconds so the probability of that occurring is n't likely. Unless you purposely turn them all at the same time.. but I imagine it could still handle that because it can handle 6,000 watts of inrush.
@@diySolarPowerFunWithRay Yes, I was asking about in-rush, but if you have verified it can handle it, fine. Fridges kick in at random times, it is very possible for them to actually turn on during the night or early hours at the very same time. However, if this happens it should appear in your logs as a overcurrent or overload. All the best
I'd like to know how long can I run a typical office setup.. e.g. a desktop gaming computer, big monitor (49"), speaker system (12" sub and bookshelf studio speakers), a 2nd laptop, a few USB devices. Going to figure this out soon myself because that is my daily almost every day of the week setup that I run about 12 to 18 hours a day depending on other factors. I'd like to try to figure out how many panels I need to keep it topped off so that I seldom use grid power to charge batteries, and can I charge 48v battery bank while its in use with the inverter. My goal is to hopefully get a weeks worth of charging + battery use without grid use, but during winter/rain/cloudy days, not sure how that will work out. Can I set up a bike and pedal my way to recharging. :D.
Funny, we think alike. I was just thinking about building a bike charging set up.
You'll want to get a watt meter and plug all those items into it so you can measure a day's worth of power consumption. Then that will tell you how many batteries/ solar panels you'll need. Remember even on sunny days the solar panels won't give you 100% output(Rarely it will when the stars align). I'd plan on 70% output.
@@diySolarPowerFunWithRay Lets do it! I'd be curious if there is a way to make one that can be efficient enough to generate a few 100watts of power.. but naturally nobody would be able to cycle for hours on end. Still in a pinch it could be useful for charging a phone or a few batteries to power a flashlight or something. From what I read a typical rider with a bike generator could do about 100watts of power give or take. So not as much as one of these cheap solar panels can put out. So wondering if there is some better way.. using multiple gears or something?
@@diySolarPowerFunWithRay Per watt meter, yah got one of those. I like that the battery with inverter (like the river pro I got) can show how much power things plugged in are consuming.
How can I set the battery to 0%?
You need to change the battery from Li to "user defined". His menu item 5 if I remember correctly.
interesting video, thanks!
thanks :)
how long will this battery last with a 1500 watt space heater on constantly. And how long at 750 watt constant.
The battery has 5120 watt hours of capacity. so running a 1500 watt load with around 50 growatt idle would be.... 5120wh/1550w = 3.3 hours. minus a bit for 85% - 90% efficiency.... So i'd say just under 3 hours. double that for the 750 watt space heater
@@diySolarPowerFunWithRay cool, thanks for the info…
@@fergman300 no prob. let me know if you have any more questions. If you end up purchasing something you can support the channel by using any links I have. Good luck
Don't run your battery down to 0% you will dramatically reduce the life of the battery.
LiFePO4 cells are not damaged if you discharge to zero.
The point is to not run it down to 0%.
It was good to figure out that setting so I could run it down to zero in case of an emergency.
You do know that you lose a lot of power by using extension cords, and your test are not super accurate. Also, they are dangerous with the power strip setup as well.
Thanks, Yeah I did another video on that. I think I was loosing 20 or 30% when the sun was fully out. Pretty bad. I'm going to upgrade to a different inverter that can put more panels in series which will cut my amp's in half.
@@diySolarPowerFunWithRay With a Series connection, the amps stay the same. The voltage increases.
@@DeeJayHouser1 yup. I have two strings in parallel right now so it will cut my amps and half
@@diySolarPowerFunWithRay Huh? The books teach you that the voltage increases in series and the amperage stays the same, and for parallel the voltage stays and the amperage increases... I have never heard of it cutting amps in half. Do you have a circuit between that is dropping your amps? I did go to college for Electronics Engineering in 1990, perhaps something has changed since then.
@DeeJay Houser you have it right. I'm just not explaining it well.
not helpful, dude. too many unknowns and failures. Would have been nice if you simply reran your test with all variables under control.
Like what?
