Features at a glance

TheSolar Power Management Module (D) is designed for 6V~24V solar panel, it can charge the 3.7V rechargeable Li battery through solar panel or Type-C connector, and provides 5V/3A regulated output (supports multiple protocols such as PD/QC/FCP/PE/SFCP). The module features MPPT (Maximum Power Point Tracking) function and multi protection circuits, therefore, it is able to keep working with high-efficiency, stability, and safety. It is suited for solar-powered, low-power IoT, and other environmental protection projects.

• Supports MPPT (Maximum Power Point Tracking) function, maximizing the efficiency of the solar panel
• Supports solar panel / Type-C power adapter for battery charging
• For 6V~24V solar panel, supports self-adaptive input voltage via DC-002 jack or screw terminal, with input anti-reverse protection
• Multi LED indicators, for monitoring the status of solar panel and batteries
• Multi protection circuits: over-charge / over-discharge / overheat / over-current, stable and safe to use

SAFETY CAUTIONS

• Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
• Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
• Do not mix use old batteries with new ones, avoid using batteries of different brands.
• When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
• Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
• Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.

Note: the 18650 batteries are NOT included.
