[RE-wrenches] Outback question

[Jay]

Is the generator power passing through the inverter to the loads, probably not?

It has performed well for him until two months ago when he started seeing huge fluctuations in the charging behaviour indicated on the Mate and flaky behaviour in the household loads. He said he’s also “burned out” a couple of generators. The AC loads remaining constant while the charging loads would fluctuate, doubling sometimes.

He found a loose wire incoming from the generator but when repaired it made no difference. I believe the problem may be the charging board in the Outback is failing. Appreciate any comments or suggestions. Also what is the current status of boards from Outback? From reading the Wrenches list I see that Outback has changed hands recently.
