2017 RT29 inverter failure?

[1Mainer50]

My battery banks were empty after the ignition switch was inadvertently left on for several days while plugged into shore power. My mechanic did an electrical check and found the inverter was outputting 5 amps instead of the 50 the spec sheet said to expect. It's an Abso IC122055 inverter. He thinks that an internal switch cut back the power as the inverter overheated, and may be broken. Last fall the boat briefly wouldn't charge while on shore power but the problem resolved itself (ha!).
Any thoughts on this? Hate in invest in a new inverter if I don't have to.

I would call help desk at manufacturer of inverter to confirm. Seems odd your situation would cause a failure.

I don't know if it's related but my battery power went too low on a long weekend and wouldn't charge. Per the manual "If the house bank drops below 10.8v you must reset the charging relay by switching on the parallel while the engine is running." It fixed my problem but the inverter was only indirectly affected by the low power.

I believe the Kisae has 4 manual output settings 5,15,35,55 amps did it possibly get programed for max output of 5 amps? I believe that many inverter/chargers have derating values if the compartment is too high or the internal temperature of the inverter is to high limiting output. I would try resetting the inverter to factory default settings and confirm it is not operating hot or in a warm compartment then retest output.
