It can charge a solar generator, aka battery inverter as well  portable AC outlet power supplies;

Useit  as a solar panel or a solar panel system;

With a Fur-rion RV Adapter from Acopower you can use it for an RV as well.

120 Watt foldable solar panel controller

This PV module comes with a 10 Ampere  solar charge controller that is pre-installed. It is a PWM (pulse width modulation) charger.

This charge controller protects the batteries against unsafe electrical conditions. It will be safe during surges and overcharge.

You have to use the controller when charging 12V batteries. Make use of the alligator clips.

Use the MC4 connectors if you want to charge a solar generator with a built-in charge controller. Plug them into the cables of the solar charge controller and it will be charging.

10 Amp PWM Charge Controller10 Amp PWM Charge Controller.

You can charge a solar generator and a 12V battery together.

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 of connection

Remember we should always connect the battery first. Then the load and last the 120-watt foldable solar panel.

When disconnecting you do it panel, load, and last the battery.

Operating the 120-watt foldable solar module

It is easy and quick to set it up with the pre-installed wires and stands.

Locate a sunlit area. Be sure it is a spot without any obstacles blocking the sun.

Now it is a matter of unfolding the 3 panels and faces it towards the sun. It will immediately start producing an output.

It is best to adjust the solar panels to realize max sunlight for as long as possible during the day. That will ensure the most power output. Use the kickstands to  direct properly.

Always connect the positive and negative leads according to the prescribed polarity.

Remember to read all the safety precautions. Then you put the 120-watt foldable solar panel into operation.

A proper battery clip connection will prevent short circuits.

Be aware that anything that covers the surface of the 120 watt solar module can reduce the output power.

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.


  • Fabric and cell surface is waterproof for outdoor usage.

  • The manufacturer uses Velcro design to keep the panels closed up.

  • With the 3 standing legs and pre-installed wires setting up and directing for max power output, is quick and easy.

  • The case includes a  pocket for holding of accessories.

  • The conversion efficiency is high.

  • The 120 Watt foldable solar panel is compact. It is light, very compact, and easy to carry and handle.

  • The  LED display is handy, it is informative and very simple to read.

  • The carry bag is manufactured with strong material. It is a handy article and can last for years to come.


  • Some people would like the Velcro flap in the storage pocket to be bigger. Once packed it seems too small to close.
  • It is imperative that we keep the controller completely dry. It is not waterproof.
