Turned all 12V lights on then heat pump....Not even a flicker from the lights. Problem solved. Thanks all.

Good find. Apparenlty the lights were getting their power from the charger and not the batteries resulting in the flicker. Plus the batteries were not being charged.

An inexpensive digital voltmeter from say Harbor Freight is a good tool for checking some basics. I'm not being critical - just saying...

Glad you found a fairly minor problem and, hopefully, it won't be a problem going forward. Another thing to consider would be adding a Soft Start on the A/C to help reduce the start-up load.

1. I do have a VOM and used it to establish the battery condition and the position of the on/off switch, since it is not clearly marked. VOM is a big help.
2. I am not sure what a soft start is. But when the a/c starts I do know it starts using less current then kicks in. Almost sound like changing gears.
