120 Watt foldable solar panel controller

This PV module comes with a 10 Ampere PWM solar charge controller that is pre-installed. 

The  controller's function is for battery protection when charging.

Use the MC4 connectors if you want to charge a solar generator with a built-in charge controller. 

10 Amp PWM Charge Controller10 Amp PWM Charge Controller.

It is possible to  charge a solar generator and a 12V battery simultaneously.

The controller also has 2 x 5 volts 2.4 amps USB ports for smaller devices.

Remember the controller and the USB port will only respond once connected to the battery.

There is  20 feet long 14AWG extension cable available from Acopower.

Order to connect

Connect the battery, then the load and lastly it will be the 120-watt foldable solar panel.

When disconnecting you do it the other way round.

Connect the  leads according as prescribed.

Before operating the 120-watt foldable solar panel read all safety instructions.

Ensure correct battery clip connection to avoid short circuits.

Remember obstacles on surface of the 120 watt solar panel reduce output watts.

To clean the 120 watt foldable solar panel surface

Clean to be efficientClean to be efficient.
  • Remove objects covering the surface..

  • Dust and dirt can decrease the efficiency and thus reduce output performance.

  • Clean  with a soft brush and use a damp clean soft cloth for remaining dirt.


  • The module is waterproof for using outside.

  • Convenient Velcro design helps  keeping the panels closed up.

  • The case comes with a  pocket for holding of accessories.
