Ian at watts247 had me tie a jumper wire between neutral and ground, at the bus bars in the vehicle main AC panel, which is fed by the growatt, because there was no neutral-ground bond in the system at the time.
Vehicle has a 3kw gasoline inverter generator, that has no neutral-ground bond, feeding a GroWatt SPF 3000 TL LVM ES, 1800w of panels, 10kw of EG4 LFPO. What I don't know, and please reply in plain english, is:
if the breaker box panel which is on the AC output side of the inverter, has the neutral-ground bond, is that bad? Should the bond instead, be made inside the growatt, where the AC-IN and AC-OUT is? Because Code or best practices seem to assume that the neutral is bonded to the ground on the INPUT side, e.g. at a conventional main breaker panel, ahead of the Growatt, not afterwards. Another way of saying is, on the supply side or grid/generator side, not the load side.
Additionally, should the AC-IN and AC-OUT earth grounds be jumpered inside the Growatt lower panel where the wiring connections are made? Or does the growatt handle that?
Please, answer in plain english: No electrical abbreviations that aren't common knowledge among ordinary people. I've read, and tried to read, threads on this, including an enormously complex but well-intentioned 'grounding made simple' that was, in my opinion, anything but simple.
Questions:
Where do I put a short length of wire to jumper connections? Panel? Growatt? Generator? Between which terminals?
Do I need a grounding rod, and if so, where, on what piece of equipment, do I attach the grounding wire to?
The generator is on the roof, securely mounted within metal feet, that were part of a server rack. It is on a metal lattice rack that is bonded to the steel frame of the vehicle (although the vehicle has composite walls, so the frame is internal). I believe the generator has a grounding lug. Should that be tied with a wire electrically, to the metal frame it's sitting on?
There is some documentation on how to bond the neutral to ground, within the generator, but that would require disassembly. I'd like to avoid that. There is a 30-amp plug plugged into the TT outlet on the generator, with the other end wired straight into the growatt AC-IN. Do you suggest jumpering it's neutral and ground inside where it connects to the growatt terminals? I don't plan on plugging this into grid, ever. I have in the past, but it's not likely into the future.
Thank you, in advance.
