1. Tuote ohiview
The Waveshare Solar Power Manager Module (D) is a compact and efficient solar charge controller designed for various low-power applications. It facilitates the charging of 3.7V rechargeable Li-ion batteries using either a 6V-24V solar panel or a Type-C power adapter. The module provides a stable 5V/3A regulated output, making it suitable for powering microcontrollers, development boards, and IoT devices.
Equipped with MPPT (Maximum Power Point Tracking) functionality, it optimizes the power extraction from solar panels under varying light conditions. It also integrates multiple protection circuits to ensure safe and reliable operation, including safeguards against over-charge, over-discharge, overheat, and over-current conditions.

5. Käyttöohjeet
5.1 Akun lataaminen
- Aurinkoenergian lataus: When a solar panel is connected and exposed to sufficient sunlight, the module will automatically begin charging the connected 3.7V Li-ion battery. The "Charge" LED (part of Solar panel charging indicators, 9) will illuminate. Once the battery is fully charged, the "Done" LED will light up.
- Type-C lataus: Connect a 5V Type-C power adapter to the Type-C input (2). The module will charge the battery. The BATT capacity indicators (8) will show the charging progress.
5.2 Powering External Devices
- The module provides a regulated 5V/3A output via the screw terminal (3). Connect your 5V device to this output.
- The Type-C port (2) can also function as a 5V output for external devices when not used for charging.
5.3 LED-ilmaisimet
- BATT Capacity Indicators (8): These LEDs light up when the battery is charging or under load. They will turn off approximately 30 seconds after the load is removed.
- Solar Panel Charging Indicators (9):
- Veloitus: Palaa, kun aurinkopaneeli lataa akkua aktiivisesti.
- Tehty: Illuminates when the battery is fully charged by the solar panel.
6. Huolto
- Puhdistus: Pidä moduuli puhtaana pölystä ja roskista. Käytä puhdistamiseen pehmeää, kuivaa liinaa. Vältä nesteiden tai hankaavien puhdistusaineiden käyttöä.
- Liitännät: Periodically check all screw terminal connections to ensure they are secure. Loose connections can lead to poor performance or damage.
- Ympäristö: Operate the module within its specified temperature range. Avoid exposure to extreme heat, cold, or high humidity.
- Akun kunto: If using rechargeable batteries, follow the manufacturer's guidelines for battery care to maximize lifespan.
