                                               Applications

Car-camping adventures;

Popup trailer;

Dry camp;

RV;

Ham radio;

Charge your car battery, marine boat battery as well other 12V portable lead acid and lithium batteries;

It also charges your solar generator;

(The recommendation is to use ACOPOWER 400wh and 220wh Solar Generators.)

It can work either as a solar panel or a solar panel kit.

The Charge Controller

5 Amp PWM Charge Controller5 Amp PWM Charge Controller.

This solar panel module comes with a 5A 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.

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

The controller also comes with 5 volts 1.2 Ampere USB port for small devices.

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

Acopower sells 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 70 watt portable solar panel.

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

How to operate the 70 watt solar panel kit

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 2 panels and faces it towards the sun. It will immediately start producing an output.

It is best to adjust the solar panel 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 70 watt foldable solar panel into operation.

Proper battery clip connection will prevent short circuits.

Be aware that anything that covers the surface of the 70 watt solar panel can reduce the output power.

Cleaning the surface of the 70 watt solar panel kit

Clean to be efficientClean to be efficient.

Remove anything that covers the surface of the solar cells.

Sometimes dust and dirt can cover the surface of  solar panels.

This can have a large decrease in efficiency and reduced performance.

Clean the surface with a soft brush. Then use a damp clean soft cloth to remove remaining dust and dirt.
