Welcome to Guangzhou HanFong New Energy Technology Co., Ltd
We have already know open-loop MPPT method, now let’s learn what is Closed-loop MPPT method. We know open-loop MPPT method is one of the method, another is Closed-loop. So what is Closed-loop?
Closed-loop MPPT method is based on photovoltaic battery output voltage and the real-time measurement of current value between closed-loop to achieve MPPT. self-tracking superior algorithm type is one of the most widely use type. The typical self-tracking superior algorithm type with two type. One is Perturbation and Observation Method，P&O and another is Incremental Conductance，INC. 4
This month Hanfong new energy released a new MPPT series controller. It with blue and white design. The transfer efficiency much higher than PWM solar charge controller.
As a professional charge controller supplier, Hanfong new energy also produce full household use solar system. include solar panel, solar controller, power inverter and battery.
