Charge your  batteries, marine batteries, also other 12V portable lead acid and lithium batteries;

It also charges solar generators;

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

Use it as a solar panel kit or only as a solar panel.

The Charge Controller

This 70 watt solar panel kit has a 5A pre-installed PWM solar charger controller. 

This charge controller is to safe guard and protect the batteries during charging.

Use the controller when charging 12V batteries. You can make use of the crocodile clips.

For a solar generator that has a built-in charger you can use the connectors(MC4's). You can just plug them into the cables and it will be charging.

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

Also the controller has a 5 volts 1.2 Ampere USB port for smaller appliances.

The controller as well as the USB port will not respond before you connect it to the battery.

You can use a 14AWG extension cable before the charge controller if you have to. Acopower is the seller of this cable.

Order in which to make the connection

We have to connect the battery, then  load and last the 70 watt portable solar module.

When disconnecting it is panel, load, and then battery.

Operating the 70 watt solar panel kit

With attached wires and the stands it is easy and very quick to set up...

Go to a  sunny area, without obstacles to block the sun. 

Unfold the  panels. Face the sun and it will  start producing a power output.

Adjust the solar panel to get maximum sunlight during the whole day for most power output. For proper direction use the kickstands.

Read the safety instructions before putting the 70 watt foldable solar panel kit into operation.

See that battery clip connection is done properly. This is to avoid any short circuits.

Remember obstacles that cover the surface of the 70 watt solar panel kit reduce  output.

To clean surface of the 70 watt solar panel kit

Dust and dirt can some times cover the surface of  solar panels. Remove it, it can decrease efficiency.

Now you can clean using a soft brush. Remove the remaining dust and dirt with a damp cloth.
