Review on LANGY Solar Battery Charger Controller, 20Amp, 12V/24V Auto Recognition, Large User-Friendly LCD Display, Compatible with Flood, Lead Acid, Gel, Lithium Battery by Boss Spangler

When I got this charge controller I wanted to see what it could do. After I connected it, I had to remove it. At 20 amps it can't take much. This is an absolutely simple controller and should only be used for a small PV system. If you only have a few panels and are short on cash, this would be a good starter controller. If you have more than a few hundred watts in a 12v system, this controller is not for you.
