Good question re Vmp, I will have to climb up on rig to find out or find manual.
There is a controller, PWM. My hunch is controller has gone bad.
Thanks for your answer!
I will check on these in the morning!
Hi!!!
Why would my voltage on my rv battery read 21.4 all of a sudden?
If generator is on, it reads 13.6.
Currently 50W panel that came with rig is connected to batteries in parallel. Went wonders once we got sun directly overhead.
Just lead acid batteries.
Pretty much a newbie. What kind...
