Hello All,
A system we installed several years ago is on an old school building
that has been repurposed to office space and small shops. The loads are
very small. The electric bill, during the short days of the year with
lots of clouds (very little solar), was around $30.

I fully agree that off grid solar has taken a major downturn. Once the
equipment became software based, the reliability dropped. Sure, there
are nice features available with these cyber enhanced systems, but the
cost in reliability makes being energy independent off the grid hard to
accomplish.

I ran into this once on an old transformer, which fortunately they

My questions for the utility
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.
