First, to the both of you, I can't thank you enough for taking your time to solve other peoples problems. I was hoping to do as little modification to the ambulance as possible at the moment. My main objective was to get an Air Conditioner working, and I have managed to get that done. The...

Yes, tested continuity with unit off, no line in or line out connected. solar array disconnector off, battery breaker off. No continuity between neutral and ground. The only continuity is between the line in ground and the line out ground. There is continuity between both grounds and the case of...

Is the Growatt faulty?? Or is it just a shitty design? Would I be having the same issue with a different inverter? And if I were to put a jumper wire directly at the output, between the ground and the neutral, how much current should I expect? Could I put a small switch of some kind on that...

So, when plugged into shore power the hot neutral disappears. I can hear the thing doing some switching in there. The line AC out will end up at this fusebox connected by 20 ft of 3C 8 AWG8 wire and by the looks of it, it does not have a neutral ground bond. Are you telling me if I create a...

What makes this more interesting, is that when I am plugged into shore power. Then the hot neutral disappears.

Could I get you to test your voltage while inverting on battery power. From Neutral to Ground

well damnit.

Mine is behaving just like that one. This inverter is powering outlets through the "Pass Through" function of another inverter. I have checked the outlets of that inverter and it does not show any voltage between neutral and ground. Though once I use the growatt as the shore power it does. There...

I did test, and their is no continuity between ground and neutral when the inverter is off. Only when it is powered on is there continuity. I think I remember testing the output of this inverter before with the tester, and it did not report a hot neutral, but I could have been plugged into the...

I am fundamentally confused as to the Growatt 3000 inverter, the screws, and if removing them is bonding or debonding them. I am placing this inverter into an ambulance, which already has an input for shore power, a breaker box, and a pass through inverter. I am just using the Growatt to supply...

Is this a bad thing?

What did you end up doing?

I have a similar issue. I have the 3000w growatt and solar in an ambulance. I am using the output of the growatt to power the shorepower of the ambulance. I have votage on both the line to ground 56v and neutral to ground 63 volts. Line to Neutral is 120vI have a gfci breaker on one of the...
