10A MPPT Solar Charge Controller 3S / 4S Lithium LiFePO4 Battery Charging Board
10A MPPT Solar Charge Controller
3S / 4S Lithium LiFePO4 Battery Charging Board
Description:
100% Brand New and High Quality
MPPT Technology --- 10A solar maximum power point tracking
High efficiency synchronous rectification step-down charge management, the highest efficiency up to 96%
Solar cell maximum power point tracking (MPPT)
Solar cell maximum power point tracking (MPPT) is to ensure that in the light intensity changes, photovoltaic cells have been the maximum output power to make full use of solar energy. Under normal circumstances, need to use the switch mode DC-DC converter MPPT function, to maintain the output voltage and charge current product (output power) to maximize.
The switching step-down synchronous rectification DC-DC conversion of photovoltaic cells to achieve the maximum power point tracking function, the input voltage up to 28V, very suitable for the input voltage and battery voltage difference between the larger applications.
Charging Management Board Features:
1. High-end technology MPPT solar maximum power tracking charge management, with trickle, constant current, constant voltage charge management;
2. The use of imported high-frequency low-turn internal resistance N-type MOS tube, high-efficiency flat high-power inductors, alloy current sense resistor;
3. High-speed and efficient charging method;
4. Dual status indicator, there is no red / green when the battery is off, the red light when charging, full of self-stop while the green light;
