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

The Solar Power Manager Micro is an ultra-low-power solar energy management module designed for 1–3 V small solar panels. Built around the SPV1050 IC with MPPT (Maximum Power Point Tracking), it maximises solar conversion efficiency even under weak sunlight — enabling charge-free, battery-replacement-free operation for low-power IoT devices.

The module charges a 3.7 V lithium battery via solar (up to 70 mA) or USB (up to 100 mA), and provides a regulated 3.3 V 90 mA output capable of handling burst current from wireless transmitters. Over-charge, over-discharge, and reverse connection protection extend battery life in long-term deployments. A 2 V 160 mA monocrystalline solar panel is included.
