Feature:

EM12-SPMPPT algorithm of fast tracking of maximum power point of PV cells, efficiency > 99%.

SOlar battery working point voltage can be manually or automatically MPPT tracking.

ALl-weather automatic operation, can also be manually, realize "sunriseworkand sunset sleep".

It canSwitch between city grid ACPower supplyandPV battery power.

AUto sleep function/pump dry protect/low frequency protection/ over load protection, etc.

WAter level detection function, can support terminal andAnalog detection.

ACcurate display PV power, PV current, operating parameters, such as pump flow.

the IGBT carrier frequency can auto adjustmentAccording toHeat sink temperature.
