BMS 3S 4S 10A 12V 12.6V MPPT Solar Controller BQ24650 LifePo4 Lithium Battery Charge Board For 80W 120W Solar Pannel System
Description
The solar cell maximum power point tracking (MPPT) is to ensure that the photovoltaic cell always outputs the maximum power when the light intensity changes to make full use of solar energy. In general, it is necessary to use a switch-mode DC-DC converter to realize the MPPT function to keep the product of output voltage and charging current (output power) maximized.
The switch step-down synchronous rectification DC-DC conversion method is adopted to realize the maximum power point tracking function of photovoltaic cells. Its input voltage can reach up to 28V, which is very suitable for applications where the input voltage and battery voltage are quite different.
Features
1. High-end technology MPPT solar maximum power tracking charging management, with trickle, constant current, and constant voltage charging management
2. Imported high frequency low conduction internal resistance N-type MOS tube, high efficiency flat high power inductor, alloy current detection resistor
3. High-speed and efficient charging method
4. Dual status indicator lights, the red/green light is off when the battery is not connected. The red light is on when charging. The green light is on at the same time when it is full and stops automatically
