My MULTIPLUS 3000 after working perfectly for a couple of years is now shutting down momentarily while connected to generator power. The unit shuts off for 10 seconds, stops passing through 120v power, then starts back into normal pass through operation.
I also noticed that the batteries are charged to 93%, charger is in absorption mode, and the charging amperage is oscillating between zero and 33amps of charge current. I am connected via my Mk3 and not getting any alarms.
Any help in diagnosis is appreciated.
