If he's not running the generator through a transformer, then he's
probably just running 120 vac off one leg of the generator, with no load
on the other leg. This imbalance will definitely cause generator
failures long term, and not reliably charge the batteries.

My question would be what is the combined generator load? Did anything change?
Anything new, solar parts or ac loads or new person around?
The max charging is around 20 amps or 2400 watts, + loads can get pretty large.
Most generators don’t have that kind of 120v capacity. I ask because he’s
burned out 2 generators which says to me his programming might be incorrect.
I’ve seen odd behavior if the generator is running too hard, if so I have
people turn down the ac input amps. It doesn’t matter where the charge amps is,
loads are priority.
And
I’ve not seen this exact set of issues. Could be settings or an actual board.
Probably not the fet board but could be either the ac or control board.

Hi Wrenches, I have a client who has a 6 year old Outback 3524 inverter. 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.
Because he’s pretty remote I’ve had him troubleshooting and he has replaced the
battery pack, switched generators, checked all the wiring. 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.
Thank you!
