## Description

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. Key Features MPPT Algorithm – Constant voltage ratio tracking for maximum solar efficiency Ultra-Low Quiescent Current – <3 µA standby draw Dual Charging – Solar (up to 70 mA) or USB (up to 100 mA) 3.3 V Regulated Output – 90 mA continuous for low-power wireless devices Battery Protection – Over-charge, over-discharge, and reverse connection Output Protection – Short circuit and over-current Solar Panel Included – 2 V 160 mA monocrystalline panel Module Specifications Management IC: SPV1050 Topology: DC-DC Boost Solar Input (SOLAR IN): 0.5–4 V Battery: 3.7 V single-cell Li-Po/Li-Ion Max Charge Current: 70 mA (solar) / 100 mA (USB) Over-Charge Threshold: 4.2 V Over-Discharge Threshold: 3.1 V Regulated Output: 3.3 V, 90 mA Quiescent Current: <3 µA Operating Temperature: −40 °C to +85 °C Board Size: 30 mm × 30 mm Solar Panel Specifications Nominal Voltage (Vmp): 2 V Nominal Current (Imp): 160 mA Open Circuit Voltage (Voc): 2.4 V Short Circuit Current (Isc): 190 mA Cell Material: Monocrystalline silicon Properties: Waterproof, oil resistant, corrosion resistant Panel Size: 50 mm × 50 mm Ideal For Wireless sensor networks Bluetooth iBeacon devices Solar-powered IoT sensor nodes Low-power environmental monitors Package Contents 1× Solar Power Manager Micro board 1× Monocrystalline silicon solar panel (2 V, 160 mA, 50 mm × 50 mm) 2× Red single conductor wire (15 cm, 24 AWG) 2× Black single conductor wire (15 cm, 24 AWG) 1× PH2.0 2-pin male power cable (15 cm) 2× XH2.54 2-pin headers Resources Product Wiki
