Clearly haunted. 2007 H 44DS with xantrex charger/inverter, has always worked fine. However, the last 2 times I used generator, ALL the lights on the remote panel keep flashing rapidly. The AC output from generator is fine, the DC output from the charger is fine, in fact it works entirely normally except for the flashing lights, fully charges batteries in usual amount of time, which are in good condition. Any ideas? I can ignore it, but is it trying to tell me something?
