MPPT 20A/30A/40A solar controller applied to the solar photovoltaic system which is used to coordinate solar panels, storage battery and load. It is a very important assembly in the photovoltaic system. It is different from other solar controllers that it is add the comprehensive protection function makes the whole solar photovoltaic system operate efficiently and safely.
MPPT 20A/30A/40A solar controller can adjust automatically the working voltage of solar panels, which can make solar panels work consistently in the maximum power point of the V-A characteristic curve in a whole day. Compared with common solar controllers, it is equipped with temperature compensation function, can make the work efficiency of photovoltaic modules increased by 30%, and can observably prolong the life of the storage battery.
