How to Make your Own Portable Solar Power Charger

powertraveller pmexp v2 powermonkey explorerHaving your own portable solar power charger can do wonders. Imagine camping out in the woods and your GPS unit suddenly runs out of energy. What now? With a solar power charger you can recharge your GPS unit back to life without the need of looking for extra batteries or a wall socket.

For this DIY project, you’ll need the following: a 400-Watt inverter, 12-volt deep cycle batteries, 12-volt power receptacle, charge controller, 5-Watt solar panel, 14-gauge red wire, 14-gauge black wire, square wooden box (two feet per side), one-inch screws, a screwdriver, a battery connector, a wire stripper, Ni-Cad batteries, and a Ni-Cad battery charger.

The first step is to place the 12-volt deep cycle battery inside the wooden box. The box will house your DIY portable solar power charger.

Next, attach the charge controller on one of the outside faces of the wooden box.

Then, strip one inch from both ends of the 14-gauge black wire. Do the same with the red wire. Use the wire stripper to do these tasks.

Using a screwdriver, open the positive terminal of the charge controller. Then, attach one end of the red wire to it. Fasten the other end of the red wire to the positive end of the battery connector.

Connect one end of the black wire to the negative terminal of the charge controller. Connect the other end to the negative terminal of the battery.

Now that we have a complete charging circuit, the next step is to connect it to the inverter. You need to attach the negative wire of the inverter to the negative terminal of the battery.

Then, attach the positive wire of the inverter to the positive terminal of the battery.

Once you’ve attached the inverter into the circuit, secure it firmly to one side of the box.

The next step is to fasten the negative wire of the 12-volt power receptacle to the negative terminal of the battery.

Then, attach the positive wire of the 12-volt receptacle to the positive terminal of the battery. Screw the receptacle onto one side of the outside faces of the box. Now, you have a 12-volt power receptacle connected to your charging circuit.

Connect the positive terminal of the solar panel to the positive input connector of the charge controller. Then, connect the negative terminal of the solar panel to the negative input connector of the charge controller.

The last step is to place the Ni-Cad batteries into the Ni-Cad battery charger. Place this in the box. Now, plug in the Ni-Cad battery charger into the power inverter. This completes your very own portable solar power charger. What a great device!
