Eg4 12Kpv handled 108 Amps per leg on surge tests on the Will Prowse eg4 video . He got (4) 4hp compressors starting with a loaded car lift all at once. Having 2 eg4 batteries . The bms allows 200 amps out per battery. A second battery will get you running a lot more . Allowing more in rush current thus more surge power! Your videos are nice clean and fun to watch.
think Will had 3 batteries and Pv was hooked up but he didnt mention if it was inputting. but ya more batteries and test again please. would love to see the results!!!
It's amazing how far this technology has come in the last 10 years.
High frequency inverter tech hasn't made any progress at all.
Your attention to detail reminds me of myself. When I do something I do it right and the detail, might take me a little longer, but when I am done the job is done right. Thanks Evan.
Great video and detail on the install. You do a terrific job explaining the install as well as the technology!
You made that install look too easy! Good job!
I enjoy the info you provide on your solar chanel. Very easy to follow
Thanks for sharing with us Evan, we enjoy all your testing and explaining the off grid systems available today. It would be helpful in the Pineywoods of Deep East Texas for the frequent outages and during the long storm and ice outages. Stay safe and keep up the great videos.
Yes the 12Kpv or 18Kpv is misleading until you look at the specs. I am considering starting slow and scaling over time to cover 100% of the power requirements at our property (25%, 50%, 75%, 100% in steps). What I haven’t considered is the PV inputs so I need to look at what is better for scalability such as a 6000XP, 18Kpv or even the new one coming out. I know you can stack, but am trying to learn about scalability and the best way for me. Early on, we had to have charge controllers and other components that come in these all in one units. I have also looked at Sol-Ark which uses a similar naming like a 15Kpv. Thanks for your videos. I am using your videos and going back to manufactures web sites to get an idea of how I can afford this. Primarily I want to have a battery backup for rolling blackouts here in Texas. Thanks again for your videos and answering my dumb questions or musings. Haha. All the best from north Texas.
This is the same unit I’m looking at to use in my house. So glad you chose it to review and test!
Clear, concise and informative. You do nice work. Thanks.
Great video Evan! You seem very excited to be doing this testing. I like it!
You always have an interesting video. I look forward to you adding the solar panels. All the best from Greensboro NC.
Rebalance your light loads on one leg and the table saw on the other. Assuming everything is 110v but 50 amp surge I’m guessing it’s 240v. I have to have a soft start on my 5 ton air conditioner. It’s a device you may be able to add to your high demand. This really helped. Otherwise it will trip my inverter when on battery power.
The table saw is 120 volt and had a 51 amp surge. And it is supposed to be only 1 horsepower. So I think the saw is getting in bad shape to surge like that.
Excellent video. Great install.
Thanks Gavin!
Great video, enjoyed your excitement. Like a kid in a candy store!!
As a I understand it, the 12Kpv is full grid interactive. Love to see you test it. I also love to see you test AC coupled via the Gen port.
Guess that set up wont handle the 73amp surge my well pump needs..darn. I would love to see more. (18K) ( Flexboss + Gridboss) oh its gonna be fun. Great videos
Thank you for your information.
One thing I forgot was to ground the battery and conduit box.
Can you please make a short video showing how to ground the inverter, battery, and conduit box? Thanks so much!
😮 your so smart!
Nice job Evan, great video!
Just plain cool Evan!
good content, thanks for sharing!
Great Video Evan. Nice clean install and as always great explanation as you do it. What brand torque screwdriver do you use?
It is a craftsman torque acrew driver
It would be neat to see if soft starters would allow you to offset those big surges and still run off the inverter.
Evan, that was fascinating. I currently have a new shop/equipment building under construction and am looking for power alternatives due to a dicey rural power grid. I think I may have found a candidate. Thanks.
Nice unit :)
Would a soft start on your air compressor allow the 12k pv to power it. If so could you install one and make a video of the install and test. Thanks for your high quality videos.
Cheers from southeast TN! Evan, when you finally get your setup grid independent, would you share break-even costs/timeframes for the house, workshop and farm (separately)?
My wife and I (mostly me 😊) want to buy some land and build a homestead with a big pole barn/shop. I would like to have an idea of how much solar costs and how long it takes to break even.
Obviously, power company costs will differ, but a rough idea would be great!
way over my head i was an electrician at a coalmine most of our equipment was run on dc everything analog in the 70s time sure changed things
I would say just add a Soft Start to that Saw & Your Air Compressor & That Would/ Should Run Both With No Problem What so Ever !
Can you post a wire diagram on how you interconnected the 12K to the panel. Looks like you are using the 12K as a backup generator to the main panel? I thought you can connect grid power to the 12K to supplement power and surge?
That's the 'saw dusk' mode I read about in the 12K pv manual.
Would be interesting to compare surge capability to a LF transformer based inverter like the Outback Radian 8K. I understand these HF inverters are less capable for surge loads. Or get a second one and set it up in parallel.
Hi there.....i would like to see if you can arrange a setup where you mix 12k with lfp cells and an bms diy style and explain the limits to that approach.......
Great video my friend, question I'm putting together a similar setup, I know you put a ferrule on the battery wire , did you use any crimping tool? or just the ferrule is ok on this situation.
Would a soft start unit let your compressor start easier and maybe a VFD for the saw and drill a to start them slower.
If I can power my 2400 sq.ft. home and a deep 240v well pump and booster pump plus any power tools on one 6000xp, oughta be a walk in the park for a 12k
What batteries are you using? Maybe you have more than Evan?
I was wondering how come nobody does the wind turbine to charge the batteries when they don't have sunlight have a blessed day 👍
In short wind is difficult to capture consistently. A wind turbine needs clean airflow clear of turbulence caused by buildings and trees. The recommendation is a min 30’ height above any surrounding structures or trees.
I have been searching for a wind generator to charge 48volt system. So far, I haven't found any that perform well.
Hi guys!
That's very impressive. Can you connect another 12Kpv to this one to suit your needs better or is it best to just upgrade to a larger version??? The table saw (and compressor) surprised me!!! I'm going to go outside and see what my regular contractor style table saw specs say on it. I'd like to be solar in my workshop someday also. So, this video is eye-opening for me. Thanks for sharing
Yes, you can use multiple 12Kpv inverters together.
I've never really understood the branding on the EG4 12KPV, but maybe you can shed some light on it for me. If it can handle 12KPV and it has an 8KW AC inverter does that mean it can also simultaneous charge the batteries with the remaining 4KPV (~50vdc @ 80amps)? I looked at the specs but I didn't see the maximum DC charging rate, only that it can do supply both AC and DC from PV simultaneously. I guess another way to ask this is if the the AC load was 0kw, could all 12kw (240amp) charge the batteries? That seams like a massive load amount of current.
Great video!! :) It's not surprise that the whole industry is moving to Hyrbrid Inverters with some grid operators pushing back on net metering.
Yes it can charge the batteries and power the inverter from 12000 watts of solar. If the battles are charged than it can only use 8000 watts to power loads.
Is there a Gasket that would go in between the Inverter and the Wire chase and the Battery ?
Thanks Evan..
I don't know of a gasket. All of the battery connections are waterproof. So water below the inverter on the battery is not an issue.
I think you need to add a second battery to get the full specs on the inverter.
The specs say max discharge current is 167 amps. This battery does 200 amps.
👍👍👍👍👍
My 5 HP compressor runs on a 30A 2 pole breaker. I think you need more battery.
Curious that the 12Kpv only requires 200ah minimum while the 12000XP requires 400ah minimum.
The spec sheet says the 12Kpv needs a max of 167 amps of discharge current. And the battery I am using has 200 amps of discharge current. So the battery is big enough for the 12Kpv.
What does your first solar system in the pole building run? I think it was called the cube?
The Canadian solar EP Cube. It runs half my house. The 6000XP runs the other half of the house.
do you have an amazon store? im curious to know what kind of torque screwdriver you use?
It is a craftsman torque screwdriver.
Silly question, how do the connectors for the PV release, should you need to pull a wire out to move it
MC4 connects are what is use on Solar Panels. There is a tool to release them. Some you can just pinch with your fingers and to release and disconnect.
I meant the actual part on the board inside the inverter. Where you typically put a ferrule on the wire, and they push in. Getting those to release a wire is a nightmare
What are your lights, HID, LED, or what? I didn't think LED used as much power as older types?
They are LED. High bay lights.
What's the 18k got for an inverter
The 18Kpv has a 12000 watt inverter
Thanks for sharing.
I think something is wrong with your table saw.
I agree
I think it may perform better with more battery. I think the specs need greater than 400ah of battery
You are thinking about the 12000XP. That is what it requires.
@@CountryViewSolar-DIYProjects Would a 12000XP and indoor batteries work on the other side of your wall where you mounted the 12KPV?
Your table saw, I presume, is wired for 110V. It should be capable of being rewired to 240V. That would half your surge current.
I agree, 240 volt table saw would solve the issue. but I don't have 240 volt outlets setup to plug it into.
need a transformer based inverter to start big motors
You need more batteries and solar to test the surge. 1 battery alone will not give you the right rating
Why aren't you warning people that the 12kpv can damage your appliances when its MOSFETs fail? Don't take my word for it, ask Google AI "Can a high-frequency, transformerless inverter damage your appliances?"
comment
Come on dude. Please give it up on promoting these cheap, Chinese-made, high-frequency, transformerless inverters with their long history of early failures. For a recent example, look at the 6500EX-48, which was discontinued only after 1 year on the market due to a high failure rate. High-frequency inverters simply don't last long in the real-world use. They offer far poorer surge capacities and because they offer no galvanic isolation, they can fry your appliances or your EV when their H-Bridge circuit fails. Don't take my word for it. Ask Google AI. " Can a high frequency, transformerless inverter damage your appliances because of no galvanic isolation?" and learn the truth about these cheap Harbor Freight type inverters.
Nice video! I think I know why your system is tripping! It can do a lot more. Just watch DIY solar with Will Prowse . Eg412Kpv. He starts four 4hp compressors with two 1500 watts heat guns all at once. And the 12kpv handles great. But he has 2 batteries hooked up to it. What is the maximum amps allowed by on battery. Et voilà you have it. 😊
