Flexmax 80 always sleeping

Post by kent79010 »

Today when I checked my system the ground fault circuit breaker was tripped. (first time ever) I turned it on and looked at the system. My FM80 said it was sleeping. Nothing I do changes it. I've checked panels and they are outputing, all wires tight. On the FM80 the IN voltage is 52.2 and the OUT voltage is 52.8. The array is putting out over a 100 volts. I've reset the FM80 and still sleeping. Thought?

How do you contact Tech support? I got a recording that said you have to contact your local dealer of which there is none.
Thanks
