Solar power
My 2023 Cherokee Wolf Pup 22RR has a factory installed solar panel. Realistically speaking, can the trailer be used with the single battery installed without it dying? I am thinking of installing a...

OP here.
I plugged it back in. It rebounded to 11.9V
I now know.
Do you mean you were charging it? Or just measuring the voltage (at the battery posts would be preferred.
40% is a bit too low.
I was reading off my panel in the trailer. The rebound I am assuming was due to the solar panel. Not bad, but definitely not good.
I'm still not following.
- What did you plug in? If you mean shore power, that just means the charger (aka: converter) kicked on. In that case 11.9v is not indicative of the state of charge. In that case, the charger is likely trying to push somewhere north of 13v but the battery is sucking it up pulling the voltage down because the battery is dead. Using voltage to estimate state of charge only works if there is no charging or loads and the battery has been left to sit for a while.
- What were the sun conditions? Mid-day it might be the panel but same issue with it not being representative of the state of charge.
Shore power was disconnected for the test.
It dropped to 11.5v. I then checked it a few hours later and the panel read 11.9v. Then I plugged shore power back in.
It was actually cloudy.
