I also have two MPP Solar inverters of the same model. Your installation video series on RUclips is the most detailed and extremely helpful. I have a question: is the ground wire only connected to the electrical panel and not to a grounding rod? When using a 240V outlet to charge a Tesla, does it still show a missing ground connection? Does it require a ground-neutral bonding plug? Thank you!
I have not tested my system yet with an EV. I've been trying to get a fiend to come over to test it. I do know the tesla charger, and many others look for a ground neutral bond.. so if you keep bonding screws in the inverters installed as they come from the factory, it should be fine. It just wants to see a proper ground even if it's not grounded to earth. I do not have mine grounded to earth at the moment.. only to the sub panel. Yes, you would aquire grounding if connected to your house ground via the AC input. IF you use grid input.. If there is no grid input, you should have the panel grounded separately to earth, but the system will still work without. I just have not gotten around to hooking up my grid input... which would in turn give me a path to earth via my house ground.. hope this helps.. lmk
Update: I just tested my system with an EV and I made a short video. Yes it needs to see a ground neutral bond. It does not care if the system is grounded at a ground rod. 2 different things. ruclips.net/user/shortsKrQK80X8JTw?feature=share
Great video! Very informative. I have 1 question regarding the ground-natural ground screw and going off grid. My understanding that the manufactures manual should provide details on the location of the screw inside the inverter. If the screw is removed to be full off grid, does the neutral and all the wiring remain the same? The only difference is I would just remove the screw?
Funny, you should ask.. I just did a detailed video on this subject . I will be releasing it today. But it will affect the wiring . Not all manuals cover this. Mine did not, and it depends on the inverter. Newer inverters don't use bond screws.. you need to know the type of bonding it uses.. look for the video later today. For now, u can watch this guy's video pt2 and pt3 of his series. I based my testing on his video. ruclips.net/video/Ky5luEx6R2M/видео.htmlsi=ooYikGcbJ_456rZO
@@natesdiysolar tyvm. My goal is to do 240v 50amp off grid. Your videos are very informational and I plan to route EG4 Load L1 and L2 to the "busbar" on the Vevor outlet panel? What are your thoughts? I'm trying my best to find downsides but to my understanding there shouldn't be any as long as the load is within range(primarily due to the ease of use of the eg4). From your past comments I have found the EG4 has a programmable neutral bond which is great! Lastly Im a novice so sorry for the extensive questions...Did you wire your inverters to the 50amp double pole breaker in your panel for the safety?

@DrBT1 I did it for safety. I wanted to have a single point of disconnect. For your inverters, I think they put out 34a, so you might need 2 of them. They recommend a 40a breaker for each inverter on the right side of the panel.
No. The eg4 6000xp I mentioned at the end of the video can do 120/240 in a single unit. Link in description.. if that's what you mean.. do you need 2 units or will one work.. with these you need 2. Eg4 6000xp just 1. They are both stackable
@RVwithDD oh yes. They have to be able to communicate. Not all inverters do. Most all in one type do. Eg4 mpp grow watt .dye etc.. See video: ruclips.net/video/D_KLSrsMI3E/видео.html
Yes you can. I make mention of that at the end 9:30 of this video. BTW I think that unit has a programmable neutral bond and uses something called common neutral. ruclips.net/video/D_KLSrsMI3E/видео.htmlsi=FQdJCY7OyIaAcwGj
I wanted to have a main disconnect breaker. Also, if I add another pair of inverters for parallel output, I could just add another breaker . Besides that, 2x #4 may be too large for the lugs, but mostly, I wanted a main disconnect.
If it's just straight 240v, then it's not possible to get 120v . My inverters are 120v to start, and I use 2 of them to get 240v . You might be able to use a step-down transformer, but I have never used one myself.
Here is a video detailing how I dealt with bonding in these inverters.

@DrBT1 if you have a single inverter I would use the bond in the inverter. If more then 1 then unbound all and bond in the sub panel
Do the inverters have to be stackable to do this?

@@natesdiysolarYou mentioned the inverter on the left and the inverter on the right. I thought that meant they had to be stackable to do it that way.
@RVwithDD oh yes. They have to be able to communicate. Not all inverters do. Most all in one type do. Eg4 mpp grow watt .dye etc.. See video:

Hey great video. I bought a eg4 6000xp it is also split phase. Can i get 240 volts off one inverter or do i need to buy another one?
Yes you can. I make mention of that at the end 9:30 of this video. BTW I think that unit has a programmable neutral bond and uses something called common neutral.

Wee. Great information. Busbars.
Why didn't you use the main lugs? I don't get it.
I wanted to have a main disconnect breaker. Also, if I add another pair of inverters for parallel output, I could just add another breaker . Besides that, 2x #4 may be too large for the lugs, but mostly, I wanted a main disconnect.
I have a European inverter 3kva 24v dc to 240 vac but my 240 vac is 240 on line one 0 on line 2 how do i convert to 120 on both lines?
If it's just straight 240v, then it's not possible to get 120v . My inverters are 120v to start, and I use 2 of them to get 240v . You might be able to use a step-down transformer, but I have never used one myself.
@@natesdiysolar ok thanks man I got a step down inverter but it has a us 120v plug I'm not sure how to connect it
I want to know what equipment i need to power a heated chicken coop. 🎉🎉
What will you use to heat it..
💪❤️🙏awesome
so these inverters are 120 v each so you need 2 inverters to make it 220v
Correct. Check out the eg4 6000xp if you need 120 240 in one box
Don’t show the wrong thing first appearance your workspace is not code compliance 30 in width
