I'm on shore power in sunny Port Isabel, TX. The Prosine display alarmed for high charging voltage; 14.8V and 0 amps. The CMP panel and my meter showed 14.6v. I turned off the battery charger and checked with Prosine to verify the inverter setup. Then I partially covered the solar panel and the voltage dropped to about 13.5V. Figuring it was the solar panel, I removed one of the connections to the Photovoltaic Controller in the battery bay. Before removing it I noticed that none of the LEDs were lit. Thinking I probably had a bad controller, I turned the inverter charger back on, assuming the inverter would control the charge. I just got back to the coach after about an hour and the overvoltage alarm was again sounding. Turned off the charger. After about 10 minutes I turned it back on. The Prosine displays 14.4 volts at 0 amps and initially goes to standby but after a few seconds switches to charge (stilll 14.4 v, 0amps).
Ideas?
Thx, Steve
