12 volt MPPT Solar Charger Module

MPPT 12 Volt 2 Ampere solar charger Module 

This is a 12 volt 2-3 Ampere complete charger controller for 1 or multi-cell Lithium-ion Battery or LiFePO4 Batteries. This module is based upon CN3722 IC which is specially designed for charging 1 or multi-cell lithium ion batteries or LiFePO4 batteries with constant current and constant voltage mode.

Deeply discharged batteries are automatically trickle charged at 15% of the programmed constant charging current until the cell voltage exceeds 66.7% of the regulation voltage. In constant voltage mode, the charging current decreases gradually, the charge cycle will be terminated when the charging current drops to 9.5% of the full-scale current, and a new charge cycle automatically restarts if the battery voltage falls below 95.8% of the regulation voltage in constant voltage mode.

The module will automatically enter sleep mode when input voltage is lower than battery voltage.

Descriptions:

  • Nominal 12 Volt (10.8V 11.1V) full charge voltage 12.6 Volt lithium battery 3 string lithium battery charge management board. 3 Ampere high current intelligent trickle, constant current, constant voltage charging management board.
  • Solar cell maximum power point tracking (MPPT) is to ensure that the light intensity changes, the photovoltaic cells have been the maximum output power to take full advantage of solar energy. In general, it is necessary to use the switch mode DC-DC converter to achieve MPPT function, to maintain the output voltage and charge current product (output power) to maximize.
  • CN3722 is the use of switching buck mode DC-DC conversion way to achieve the maximum power point tracking function of photovoltaic cells, the input voltage up to 25V, very suitable for input voltage and battery voltage difference between the relatively large applications.

Features Of 12 volt MPPT Solar Kit

  • High-end technology MPPT solar maximum power tracking charge management chip, with trickle, constant current, constant voltage charging management.
  • The use of imported high-frequency low-conduction resistance double MOS tube, high current diode, high efficiency flat high-power inductors, alloy current detection resistor.
  • High-speed and efficient way of charging, heat small, fast.
  • Dual status indicator light, no battery when the red light flashes green light is always on, charging red light, full of self-stop while the green light.

Specifications Of 12 volt MPPT Solar Kit

  • Input voltage : 18 Volt nominal solar panels (no load about 21V solar panels)
  • Output voltage : nominal 12 Volt  (10.8 Volt 11.1 Volt ) filled with voltage 12.6 Volt lithium battery, 3 string lithium battery charge management
  • Output current : maximum constant current 3 Ampere (Charge current > 2 Ampere, please add heat dissipation)
  • Wiring method : Welding plate
  • IN + : input positive,      IN -  : input negative (SOLAR)
  • BAT+ : battery positive,   BA- :  battery negative
