I'd like to leave my fridge running whilst I'm not using the van, so I can have cold drinks whenever I may want one.
However, I dont want to be using battery power, what I'd really like is to only have power to the fridge only if there is sufficent solar to run it.
Is there any output indicating solar availability on a bluesolar solar charger that could be used to drive a relay?
Or any other way of doing this? Maybe using the output voltage, or the voltage at the solar input?
