12-24V 10-40A LCD MPPT Solar Panel Battery Regulator Charge Controller USB Description: This is a three-time controller into the evening (evening) working time ,an interval of rest or pause time,Dawn working time (morning light function),the user can according to their needs ,set a different time. This is a compatible MPPT charge controller PWM intelligent/efficient/energy saving, It not only has efficient MPPT controller charging function to automatically track the maximum power point, 10%-30%higher than the ordinary controller charging efficientcy, also has standby energy saving, more than 30% energy than ordinary controller, the standby power consumption of only 10mA-15mA. MPPT 10A/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 10A/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.
