solar charge controller
The basic criteria for selecting a controller includes the operating voltage and the PV array current. Controllers are critical components in stand-alone PV systems because a controller failure can damage the batteries or load. The controller must be sized to handle the maximum current produced by the PV array.
There are two types of controllers: series and shunt. Series controllers stop the flow of current by opening the circuit between the battery and the PV array. Shunt controllers divert the PV array current from the battery. Both types use solid state battery voltage measurement devices and shunt controllers are 100% solid state.
