Solar Power Manager Micro (2V 160mA Solar Panel Included)

Solar Power Manager Micro is a micro power, high-efficiencysolar power management module, designed for powering IoT based low-powerwireless sensors or controllers with 1V~3V small sizesolar panels. Benefited from its extremely low power dissipation andMPPT (maximum power point tracking), the module is able to maximize the conversion efficiency of solar energy under weak sunlight. These features make low-power wireless devices charge-free and battery replacement-free possible by pure solar power.

The module employs constant voltage ratio MPPT (Maximum Power Point Tracking) algorithm to maximize output power of the solar panel under various sunlight. It can charge a 3.7V lipo battery through solar or USB, providing charge current up to 70mA or 100mA respectively. A 3.3V 90mA regulated output can handle burst current of most low-power wireless devices during transmitting or receiving. Inlow-power solar projects, lipo battery may suffer from over-discharge problem when it is cloudy for days, or the capacity of battery can not meet the deviceأ¢â‚¬â„¢s need. The battery over-charge and over-discharge protections are designed to prevent such problems to extend battery life.
