A comprehensive guide on building a solar powered system, including instructions on installing cooling fins, connecting batteries, and integrating controllers like Arduino or Raspberry Pi for efficient energy use.
Build a solar powered system
- Stick the black aluminum cooling fin (50mm * 50mm) within the frame marked “Cooling Fin” at the bottom of the module through the blue thermal silica gel. Stick the black small aluminum cooling fin (7mm*7mm) through the blue thermal silica gel on the surface of the two FETs near the BAT IN terminal as shown below.
- Connect a 12V lead-acid battery to the BAT IN terminal.
- Connect a 18V rated solar panel to the SOLAR IN terminal..
- Connect the controller such as Arduino or Raspberry Pi to USB1, and connect the load (mobile phone, motor, lighting equipment, etc.) to OUT1-2 or USB2. Note that you need to plug the jumper to ON of the blue header to turn on the output (plug to OFF to turn off).
