Inverter issue

[Sanford]

Was using inverter to power unit while loading for a trip. Works fine with engine running, goes to a power save mode after cutting engine. Then get the message shown below. Batteries 3 years old, normally stored with power switch in on position and with 50 amp service. suggestions?

Have you batteries checked. Three years in the heat of Florida or AZ is about all you can hope for. Bet they are dying.

Yeah, I plan to check them tomorrow. Probably replace them with AGMs. Thanks.
