I've got 4 of the 250W Saronic solar panels, and I am sourcing a reg to equip.
Heard a lot talks on the MPPT and PWM regulator, is the MPPT so distinctively efficient that the PWM?
It seems to me MPPT could make a storey of some wasted power, and charge them back to the battery(don't know this is what's really happening), it's just the terminology so confuse me off!
I think I've got enough power supply, but not intending to ruin them with dodgy solar reg. If the reg is broken, would it damage the solar panel?
Any advice will be much appreciated!
