GS8048, Mate 3, FNDC, Hub all quit --- blank!

Post by RJRsolar »

Everything seems dead. Only outward sign is the right-hand 175a c/b was tripped. Reset ... nothing ... everything is blank; no power. All c/b's ON.
This is a ten+ year old system.
Where do I start? Is there a single point of failure that would result in this?

The battery could certainly be a single point of failure.
Measure the voltage at the battery terminals, then at the load side of the inverter main battery circuit breakers.

Thanks raysun: That certainly would do it, if no voltage. I have a Midnite Solar battery monitor on the pack and everything looks good, however that doesn't mean it is still good at the breakers. Tomorrow morning, I'll pull up a stool and my trusty VOM and survey inside the Load Center.
Should it look like a catastrophic failure, it there a rehab, rebuild, service available? In the Air Force, we called it IRAN. (Inspect & Repair as Necessary.)

It will be interesting to understand why the one inverter main battery cb opened, and if it is functioning normally. Also, what's "upstream", connected to the battery (+) bus, and if there's anything that smells bad in there. 😉
