Introduction of MPPT solar controller
MPPT means Maximum Power Point Tracking, it is more advanced solar charging mode. In view of feature of solar panels, there is a Maximum Power output Point, and this point under changing light intensity and temperature. Using traditional PWM solar charge controller, the voltage of solar panel will be damped by battery, the voltage can not be maintained at charge the battery, greatly reduce the utilization rate of solar panels. MPPT technology adopt high efficiency DC-DC power transform technology, with advanced algorithm to track the MPP of solar panels in actual time to obtain Max power from solar panel for charging battery. Compare with PWM controller, MPPT solar charge controller could increase the energy utilization rate 15%-30%.
Feature:
Advanced MPPT technology, fast and stable track the Maximum Power Point, tracking accuracy 99.5%
Adopt Synchronous Rectifier Technology, significantly improve the transfer efficiency of circuit, maximum 98%.
accurate identification and tracking multi peak power point function
PV array limited power input function, to ensure that the controller does not overload operation under any conditions.
Widely range of Maximum Power Point of PV array, Max PV input Voltage 75V.
12/24VDC system voltage automatic recognition
Humanized LCD displaying, dynamic display operation data and working state
Built-in operation log, account system working state
Multi load control mode: Normal Mode, Sensor Mode, Timer and Sensor Mode
3 stages charging mode, Sealed, Gel, Flooded, LiFePO4, Li(NiCoMn)O2 battery selection procedure
Temperature Compensation Function
Accumulation function of charging and discharging, actual time display power generation function
Fullest digital protection functions: Reverse connection, Overcharging,
