Waveshare Solar Energy Manager (C)

SAFETY PRECAUTIONS B>
1. Li-ion and Li-Po batteries are quite unstable. They can cause fire, personal injury or property damage if not properly charged or used.
2. Do not connect the polarities reversely when charging or discharging the battery. Do not use the bottom charger/charging panel to charge the battery.
3. Do not mix Use old batteries with new ones, avoid using batteries of different brands.
4. When you buy lithium battery, you need to make sure the battery specification is compatible with the expansion board. Choose the batteries from the formal manufacturer and make sure the batteries work stably and safely by the aging test.
5. Lithium batteries have a limited cycle life, they also deteriorate as time passes. It should be replaced with new ones when the batteries reach their max cycle life, or work beyond two years, whichever comes first.
6. It should be placed carefully and correctly, keep it away from flammable and explosive items, away from children, avoiding any safety accident caused by careless storage.
Features B>
The Solar Power Manager (C) is compatible with general 6V~24V solar panels. It can charge 18650 rechargeable lithium batteries through solar panel or USB Type-C connection and provides 5V/3A regulated output (with multi-protocol support, including PD/QC/FCP/PE/SFCP).
The module is equipped with MPPP (MAX Power Point Tracking) and multi-protection circuits, so it can continue to work with high efficiency, stability and safety. It is suitable for solar energy iot, low power and other environmental protection projects.

1. Support MPPP (MAX Power Point Tracking) function, max the efficiency of solar panel
2. Flexible battery charging: by solar panel or USB Type-C adapter
3. Compatible with 6v~24V solar panels, DC-002 jack input or screw terminal input
4. Onboard MPPT set switch, select the closed level to the input level to improve the charging efficiency
5. On-board aluminum electrolytic capacitor and SMD ceramic capacitor, reducing ripple, stable performance
6. Built-in battery holder, support 3x 18650 rechargeable lithium batteries
7. Multiple LED indicators, for monitoring the status of the solar panel and battery
8. Multi-protection circuits: over-load / over-discharge / reverse-proof / over-heat / over-current, stable and safe to use
