So we got the coach home from the dealer this weekend.
Picture here: Soon To Be New Owner
Things mostly went OK. I have some odd inverter behavior I'm not sure is normal.
Once I start the generator and the inverter panel shows "AC in", I have some (not all) 120v outlets that blink in and out. The green "AC In" light also flashes quickly with the same frequency as the 120v outlets going out. Outside in the inverter bay, the inverter is clicking with the pulse of the green light.
After about 5 or so minutes of this going on, the clicking, pulsing outlets and green flashing light stop, the green light stays on full and everything works fine.
I also sometimes get a red blinking fault light (once per second) which indicates a low battery. I'm going to investigate this further to see if I've got a bad battery. However, the inside panel shows batteries are fully charged.
Interested to hear what "normal" behavior is for other Berkshire owners.
