diy solar

new to all this help lmao

neone? i would be right with the specs says voc can be 40v meaning panels up to 40v can be used?
 
The spec sheet also likely says 40v panels will be shunted down to charging voltage...

a pwm controller is simply a controlled direct connection to the battery.

a 40v panel shunted down that far will be very inefficient, and will likely degrade from heat and fail rapidly.
