Description:
12V MPPT Solar Panel Regulator Controller 3 Series Lithium Battery Charger Board Charging Module
Description:
Maximum power point tracking (MPPT) of solar cells is to ensure that the photovoltaic cells always output the maximum power when the light intensity changes, so as to make full use of solar energy.
In general, switch mode DC-DC converter is needed to realize MPPT function and keep the product of output voltage and charging current (output power) maximized.
Cn3722 is to use switch step-down mode DC-DC conversion 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 with large difference between input voltage and battery voltage.
Feature:
1. High end technology MPPT solar maximum power tracking charging management chip, with trickle, constant current and constant voltage charging management.
2. Imported high frequency and low on internal resistance double MOS transistor, high current diode, high efficiency flat high power inductor, alloy current detection resistance.
3. The large aluminum heat sink at the bottom ensures stable operation for a long time with high current.
4. High speed and efficient charging mode.
5. Dual status indicator light, the red light is flashing and the green light is always on when the battery is not connected, the red light is on when the battery is charged, and the green light is on when the battery is full and stops.
Specification:
Input voltage: About 18V nominal solar panel (about 21V no-load solar panel)
Output voltage: nominal 12V (10.8 11.1V) full cut-off voltage 12.6V lithium battery, 3 series lithium battery charging management
Output current: maximum constant current 3A (Please add heat dissipation if charging current is greater than 2A)
Wiring mode: pad in + input positive, in - input negative (solar) bat + battery positive, Ba - battery negative
