![]() Also, i am not sure why your battery voltage would increase while the solar voltage drops. ![]() I am confused by the solar V.is this a reading from the regulator? My understanding is the the amps would taper off as the battery reaches capacity, but the charge voltage has to remain above the battery voltage so it can 'push' the charge in. Battery voltage and the voltage measured directly off the panels seems fine. Starbord panel: 20 V Port panel: 20.5 V Battery V 13.2 Reconnected everything checked other terminals and + terminal block to battery tightened 1/2 turn. 130PM Measured battery voltage at regulator: 13.65 (this is not low!) Measured voltage at solar input to regulator.69.74 volts Disconnected and separated panels. When I left the boat yesterday, and when I arrived today, the status light was flashing red on on the regulator I've since RTFM and know now this means low battery voltage, not solar fault. ![]() I had a chance to do some more measurements today: Again, the system: 2X80 Sharp solar panels, BP (Steca) GCR 2000 regulator, 2X80AH Lifeline AGM batteries, OzeFridge refrigerator exclusively on load terminals of regulator. ![]()
