I have a 3kw EG4 unit now which seems to work better related to the MPPT controller and its voltage tracking.

You can technically run 2 of them because breaker panels have two 120 volt sides or rails. So one on each rail. BUT!! You cannot run 240 volt appliances across both rails because the AC is not synchronized. You need 2 units that communicate which each other to be able to do 240 like that. So i'm sure its very unsafe to run 2 that are not communicating but if all you need is 120, then its technically something you *could* do.

yes absolutely it would. great idea!

I don't know about the bonding there. Thats a tricky subject so I won't comment. I'll let an electrician say something there. I didn't bond anything myself though, just used it as is.

How have you gone with finding further info?

@@MicahGallant the neutral ground bonding is kinda difficult with thos unit. If its bonded at the ac input which it will be if you have a ac input then it will not be bonded at the ac out put. When you bond your neautral to ground as you are supposed to do on the ac output then it works right until you plug in the ac input and it trips the gfci. So the trick to make it work right and safely is to have a switch on your ac output ground. Have acoutput unbounded while using ac input and when you switch to solar or battery you need to flip a switch that bonds your neutral with ground

You do need a earth rod with these systems if you go completely off-grid. I found out the hard way. Everything that was being charged gave me a tingle, because I did not earth the unit. Ended up earthing the unit to the houses AC and no more problems.

You definitely need to ground your off grid home

Good question. I don't know the max size. Any standard household wire fits in for the 120 volt output, and its meant to accept standard solar cables for the input, the size you'd buy off amazing for solar panel arrays. So it accepts all the standard stuff

had issues, MPPT wouldn't check voltage quick enough to take full advantage of the power output. Known issue with these units

.most definitely

I sold mine. It was lower voltage then the standard 48volt batteries. Never had it long enough to see longevity. I have raw lifepo4 cells now built into a 15 Kwh battery which is working great so far.

@@MicahGallant pretty awful battery to be honest. I'll be getting rid of mine as well

Not the box. Its a separate wire into the bottom supplying 120volts. Input only

so you mean the AC IN of your inverter is connected to the wall outlet of your house by that black wire tapped with red wire? is the ground connected as well or just the live and neautral wires. tyia

cause I wanna know if I can do so. cut a power cable and get the live and neutral wires, then plug to wall outlet and then to inverter. would that work?

pretty sure you need minimum... probably 80 or 100 volts or something. 22v is low and probably not enough to wake it up basically. Try them in series, this unit takes up to 150 volts if its the same one. You should get it near max of the top voltage imput to maximize efficiency of the mppt controller

@@MicahGallant This proved to be correct. One panel was not enough to detect the pv input. I hooked up two 200w panels, and I now have a happy green blinky light. Thanks for your reply. Great channel.

@@MicahGallant So for the record at minimum around 40v to turn on the solar charging.

Are you trying to draw 3000 watts fro grid? It cant do that on a 15 amp breaker

@@MicahGallant I figure it out, the problem was when i connect the AC input the there is a ground to neutral from the wiring of the house, so when I trying connect my living room to inverter it kept popping the breaker. So what I end up do just run a hot to the living room cause, neutral there already. Cause I turn my main grid breaker off and supply current to the entire living from an outlet.

That no posible. You choise the wrong , you need to get split fase or 110V inverter

I can't confirm that. I know many inverters out there do support that though

I don’t think it does. Unless there is a setting I have missed. But, from what I have observed, it shuts PV input off when the batteries are full. It actually seems to regulate the Watts down until full. I hate to miss out on the sunlight that I could still convert.

Great question, i think you at least need a tiny 48 volt batter, could be 2Ah battery, just something to connect it to.

There would be a bypass control available. Mechanical or auto but talk to a electrician

Yes, need battery ideally. Will it work with no grid and no power? I don't recall, I think it does but might be wrong.

I sold this and moved to a 3kw EG4 inverter. At the time it was still working. Problem with these is the MPPT doesn't reset enough or quickly enough to adapt to changing solar array voltages so you don't make as much power as you should. So thats a bug or something there.

I sold it after a year. the mppt doesn't reset based on incoming voltage properly with this unit. Went to 3kw signature solar inverter, eg4, it works great and has for multiple years now

I've upgraded to a 3kw EG4 unit as the mppt was not resetting based on higher voltage through the day. Otherwise it gave me no troubles.

Thanks. Looking for 5000 watt unit. Sungold 5000 watt unit doesn't look like it has a problem.

this one was 120 volts
