World’s Leading Solar Controllers & Inverters

A solar charge controller is a solar-powered voltage and current regulator. They are used in off-grid and hybrid off-grid applications to regulate power input from PV arrays to deliver optimal power output to run electrical loads and charge batteries. Solar charge converters are also commonly called solar charge regulators. Solar charge controllers maintain batteries at their highest state of charge without overcharging them to avoid gassing and battery damage.
