The Solar Power Manager (C) is compatible with general 6V~24V solar panels. It can recharge the 18650 rechargeable Li-ion batteries through solar panel or USB TYPE-C connection, and provides 5V / 3A regulated output (with multi protocols support including PD/QC/FCP/PE/SFCP).

The module features MPPT (Maximum Power Point Tracking) function and multi protection circuits, therefore, it is able to keep operating with high-efficiency, stability, and safety. It is suitable for solar powered, low-power IoT, and other environmental protection projects.

Features

• Supports MPPT (Maximum Power Point Tracking) function, maximizing the efficiency of the solar panel
• Flexible battery recharging: from a solar panel or USB TYPE-C power adapter
• Compatible with 6V~24V solar panels, DC-002 jack input, or screw terminal input
• Onboard MPPT SET switch, select the level closed to input level to improve recharging efficiency
• Onboard aluminum electrolytic capacitor and SMD ceramic capacitor, reducing the ripple, stable performance
• Embedded battery holder, supports 3x 18650 rechargeable Li-ion batteries
• Several LED indicators, for monitoring the status of solar panel and battery
• Multi-protection circuits: overcharge / over-discharge / reverse-proof / overheat / over current, stable and safe to use

How to use?

1. Turn the switch to ON and press the BOOT button. The LEDs will turn on and indicate the capacity.
2. Connect the solar panel to DC-002 or the screw terminal with the adapter. If the connection is correct, the Solar Charger indicator turns on. If you reverse the connection, the Solar Warning indicator will turn on. The Solar Done indicator will turn on if the battery is fully charged and turns off the Solar Charge indicator.
3. If you connect the power adapter to the TYPE-C interface, the Quick LED indicates the fast charge mode. The LED is off if your charger doesn't support a fast charge. The indicators of capacity flashing when charging and turn off when fully charging.
4. The Type-C interface can only be used for discharging, you can connect it to power other USB devices.
5. USB -OUT interface can be used for powering other USB devices.
