MPPT Smart Solar Charger Controller 40A 12/24V

Raise energy conversion efficiency

The MPPT Smart Solar Charger Controller adopts MPPT (maximum power point tracking algorithm) control algorithm, which improves the efficiency of solar system energy due to the capacity to quickly track the maximum power point in any environment. The MPPT Solar Charge Controller also adopts the RS485 communication protocol, which can meet monitoring demands. It can be used for solar telecom base station, solar BTS, solar household system, solar street lamp system and solar monitoring systems.
