I have a 100/30 charge controller that was showing over voltage errors for 5 days...100.3 - 102 volts.I added a 5 watt resistor to lower the no load voltage condition on the panels. There is now no output from the controller. It shows 97 volts from the panels and the batteries at full float. I have four panels on my RV and a 2000 watt Trace inverter / charger with it's own controller. I think I may have blown the internal fuse. Is there someone in Phoenix, AZ that can fix it? I just bought this controller in August of this year.
