Good day:
I installed a MPPT 10/20 about two months ago with a 100w Renogy solar panel, suitcase, in my Ford Escape to power two (2) AGM batteries which are uses to primarily power a 12v refrigerator and a CPAP machine. The solar panels are not charging the AGM batteries.
Everything was working well then suddenly the indicator for watts kept close to zero (0). Prior to this change it was consistently in the high 80s and/or low 90s.
Through this period, I have been in the desert of Arizona, USA, under clear blue skies and intense sun. My travel mates have the same product and have no problems and are unable to assist me.
An example of readings from the Bluetooth are as follows:
Solar = 1w
Solar Voltage = 21.04v, Current = 0.0A
Battery Voltage = 13.79v, Current = 0.00A, State = Float
Load Output State = Off, Current 0.0A, Power = 0W
I need help. Please advise.
