<p>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 what Kirk said: it
should only be bonded N-G at one and only one spot. Check sub
panels too. My record was seven N-G bonds on one site. It caused
the shower to be energized; the customer thought that was
normal....(don't touch the shower head!?!).....That site even had
a N-G bond in the well pump wiring! Took 3 days of unF***ing that
wiring to finally get it.<br>
</p>
<p>It ain't safe, until it's right. The GFCI is doing its job, and
so is the Magnum. Now the electrician has to do his job. Unless
you wired the whole house, you're On to fix it. Especially off
grid, I see an amazing bunch of DIY garbage. Find out who did the
original wiring. Probably not a pro.<br>

folks:<br>
<br>
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.<br>
When we attempt to use the PFC (Power Factored
Charger), the Gen Set’s GFCI outlets trip. Thus far
we have verified the connections are secure, assured
that the gen set is grounded, disconnected the jumper
within the E-Panel between the ground buss and
neutral, checked AC voltages, removed the MNSPD’s from
the buss(s)… Stumped now on what an appropriate next
step should be. How do we get the PFC to function
properly? What are we missing?<br>
<br>
Best,<br>
