All of a sudden our inverter beeped and now is showing a E1. I can’t find what that means and what we need to do. We are hooked to shore power and have been for the last 6 days with no issues except for this now. We have a residential refrigerator. This is a Montana HC 331 rl 2022. I can’t seem to figure out how to get it ack to show the battery percentage
