The Charge Controller

This solar panel module comes with a 10A pre-installed solar charge controller. This is a PWM (pulse width modulation) controller.

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. Use the alligator clips.

To charge a solar generator with a built-in charge controller you can use the MC4 connectors. Plug them into the cables provided with your solar charge controller and charge.

10 Amp PWM Charge Controller10 Amp PWM Charge Controller.

It is possible to charge a solar generator and a 12V battery at the same time.

The controller also comes with 2 x 5 volts 2.4 ampere USB ports for small devices.

The charge controller and the USB port will only respond once you connect it to a battery.

Acopower sells 20 feet long 14AWG extension cable. This is to use before the charge controller if needed.

Order of connection

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

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

How to operate the 120 watt foldable solar panel

The pre-installed wires and stands allow for easy and quick set up...

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

Now it is a matter of unfolding the three 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 for proper directing.

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.

Cleaning of the 120 watt foldable solar panel surface

Clean to be efficientClean to be efficient.
