CN3791 6V MPPT Solar Charger Module for 3.7V Li-ion Battery

The CN3791 MPPT Solar Charger Module is a high-efficiency Maximum Power Point Tracking (MPPT) battery charger designed for single-cell Lithium-ion or Lithium-polymer batteries. Specifically tuned for 6V solar panels, this module utilizes the CN3791 tracking integrated circuit to automatically adjust its input power draw, ensuring your solar panel operates at its peak output performance even under varying sunlight conditions.

This module is ideal for off-grid IoT applications, remote sensor nodes, solar-powered smart home devices, and DIY electronics projects. It features complete charge management, including constant current and constant voltage charging phases, automatic recharge, and dual status indicators for real-time monitoring. Compatible with popular microcontrollers like Arduino, ESP32, and Raspberry Pi, it provides a reliable power management solution for sustainable outdoor deployments.

Features:

• True MPPT Technology: Maximizes solar panel efficiency by tracking the maximum power point of 6V solar panels.
• Complete Charge Management: Designed for single-cell 3.7V Lithium batteries with a 4.2V overcharge protection threshold.
• High Charging Current: Supports up to 2A charging current for rapid battery replenishment.
• Dual Status Indicators: Onboard LEDs provide clear visual feedback for charging and fully charged states.
• Convenient Connectivity: Equipped with PH2.0-2P connectors for secure, solderless battery and solar panel connections.
• Automatic Low-Power Sleep Mode: Automatically enters a low-power state when the solar panel voltage drops below the battery voltage.
