Hi!
We have a 2022 Keystone Outback with Solarflex 200i, a 200W solar panel, Victron 75/15 charger, 50 amp service and two 12V batteries.
A few weeks ago, my husband cleaned and sealed the roof. The next day, we left for a 4 day camping trip, plugged in to shore power at the campground and all worked fine. We brought the camper home and later that night I noticed the fridge was way above temp. As we had to leave town the next day, in the car, we turned off everything and emptied the fridge. We returned after 1 week and the batteries appeared to be drained (multimeter test on each battery showed ~ 4 V). At the same time, Victron controller light was blinking blue.
Today, the batteries tested at ~2 V each, no lights working on the battery/fresh/black/grey display inside the coach. Thinking the roof cleaning and sealing may have dislodged a solar contact, hubby got back on the roof and used electric spray cleaner on the contact attached to the roof, which showed some type of green corrosion. Plugged it back in and the Victron controller light was solid blue. Suddenly, the batteries tested at 12.05 and 12.20 V and the interior coach display was lit up normally! We are not plugged in to shore power. Obviously, the batteries did not suddenly charge in 30 seconds?!
We are hoping the batteries will be fully charged by noon tomorrow, after the sun has shined on the panel tomorrow morning.
Questions:
1) Why would the corroded solar plug have anything to do with the obviously false readings we got on the 12V batteries?
2) If our solar panel ever broke or was removed, does that mean the 12V batteries would show no charge? (Not logical to me but...)
3) Is there anything we should be concerned about regarding this odd battery behavior?
Thanks
