charge controller

The charge controller is a controller used in photovoltaics (PV). The charge controller is an electronic component in stand-alone systems, i.e. in self-sufficient photovoltaic (PV) systems that are equipped with their own battery

. The charge controller is connected between the photovoltaic system and the battery, it ensures the correct charging current of the batteries, protects them against overvoltage and deep discharge and controls the maximum power point tracking

(MPPT). Charge controllerscan be designed as series controllers or as shunt controllers connected in parallel. When limit values are exceeded or undershot, the charge controller interrupts the circuit to the battery.

The charge controller is rated according to the system power in peak watts (Wp) of the PV system. The maximum current can be calculated from the system power and the output voltage.
