On recent camping trip while plugged into 50a power pole the following problem occurred. AC worked fine, however DC worked as follows. With no lights or any other DC devices operating Voltage at panel indicates 13.7 volts. After turning on 1 or 2 lights voltage dropped to 12.5 volts. After turning on another light, ( any other light) lights blinked and turned dim. After a few minutes voltage read 8.7 volts. Refridge also beeped indicating Low DC. Checked power at pole and read 120v phase to ground on both feeds. Turned lights off and refridge went back to normal. Went to bed. Woke up and checked batteries, 13v at terminals.
Adding to DC load worsens the issue.
Does it sound like the issue is the converter or the batteries? Any other ideas would be helpful.
