Hi, happy holidays to all. Of course it sounds like a dual bonding situation. Inverter generators are normally floating neutral, rotating generators are normally neutral bonded internally in the generator. The GFCI detects a neutral current on the ground wire. If the generator is bonded interna

If all else fails, cut the equipment ground prong from the attachment plug to the generator. The generator is internally grounded. You appear to have an internal ground in your system somewhere. --- On 2022-12-16 13:35, Kirk Herander via RE-wrenches wrote: You may have neutral and ground con

Chris, I also found Kirk's response to capture what I would've checked first. Ray is correct about multiple neutral-ground bonds, but there's a point that I think has been missed. You didn't identify the generator, and I'm going to assume that it's a portable gasoline unit. They have GFCIs on

Undoing the N-G bond at the E panel may not do it either.  Are you sure neutral isn't also bonded in the main distribution panel?  It usually is bonded at the generator, so you definitely have to unbond there.  I'd say 60 to 70% of off grid systems are not bonded correctly that I've seen.  Just

You may have neutral and ground connected at more than 1 location, meaning at the genset and in house panel, which means the ground is carrying current back to the generator in parallel with the neutral. I remember with some Honda portables we had to float the neutral at the genset or the inverter

The easy answer is try another genset ! You have to be more specific, did it ever work? Is it new? etc. Good Luck ! Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ e-mail offgridso...@sti.net text 209 813 0060 On 2022-12-16 10:04 am, Chris D

Hi folks: We have a new Magnum MS4024 mounted on an E-Panel using a MidNite Classic 150 and Whiz-Bang JR with power coming from an array of Trina TSM365-De06X-05(II) (three strings of three) with the ME-RC50 and a HUP SolarOne 6-85-14/24 battery. When we attempt to use the PFC (Power Factored Ch
