Description

This MPPT solar charger is designed for single-cell lithium batteries, enabling maximum power extraction from solar panels to charge efficiently. It's simple to use—connect a solar panel on one side and a battery on the other, and charging begins instantly.

Key Features:

• MPPT Technology: Ensures maximum power from solar panels, adapting to light intensity changes.
• Input Voltage: 6V, 9V, or 12V (module-specific).
• Output Voltage: Nominal 3.7V, full stop at 4.2V, for single-cell lithium batteries.
• Charging Current: Up to 2A, set via external resistor.
• Protection: Includes overvoltage, trickle-charge, auto-recharge, and charge status indication.
• PWM Frequency: 300kHz.
• Connectors: 2-pin PH2.0/JST for easy integration.
• Environment: Operates from -40°C to +85°C.
• Size: 45 x 20 x 9.5 mm.

Equipped with a CN3791 power-tracking circuit, this charger simplifies efficient solar energy use for single lithium battery projects.
