Inverter/Batteries/Controller????

HELP!

My Xantrex controller is blinking and its lights are rotating like an '80s disco and I can't get the house batteries to hold a charge(only a couple years old).

This happens when it is plugged in to shore power, when the generator is running, or the inverter is on.

Is it the controller, batteries, transfer switch, or inverter?

Try pulling the plug for the battery temperature sensor on the inverter.

You're BRILLIANT, I say. BRILLIANT!

The simplest things are always the best things! (Including the best fixes)

Thank you.
