Our high performance solar charge controllers increases battery life by preventing overcharging. Overcharging can cause corrosion and buckling of the lead plates, increased battery water loss and excess hydrogen gas.

The solar charge controllers also prevent power loss back into the solar module at night, so an external blocking diode is not required.
