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

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- AWG
- American Wire Gauge is a numbering system for wire thickness, where a lower number means a thicker wire. The AWG rating matters because thicker wire can usually carry more current with less voltage drop and heating.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- iBeacon
- iBeacon is Apple’s Bluetooth beacon format for broadcasting an identifier that nearby devices can recognise. Support for iBeacon matters when building proximity or location projects that need compatibility with apps or systems using that format.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- monocrystalline solar panel
- A solar panel made from single-crystal silicon cells, commonly used where good efficiency is needed in a compact panel. This matters when estimating how much sunlight and panel area are needed to keep batteries charged.
- VOC
- Volatile organic compounds are gases released from things like paints, cleaners, smoke, and some plastics. A VOC reading helps indicate indoor air quality, but it is usually an index or estimate rather than a direct identification of each chemical.
