Making a portable solar power generator is a great way to provide yourself a reliable energy back-up in the event of a power outage. While a small generator can’t provide power for an entire house, it can provide enough power to operate lights and a few small appliances through much of the night. Then you will at least not be relying solely on candle power to see in your home during a power outage. Also you will have a green source of energy. This will allow you as you can afford to do so to build up the scale of it to eventually power your entire home.
To construct a portable solar generator you will need a few things to begin the project. The first of these is a battery box with exposed positive and negative battery posts. The next thing you will need is a deep cycle battery. After this you need a 400 watt inverter, a DC power outlet, a 15 watt solar panel, and a 7 amp charge controller. As the last things you will need to have on hand about 5 feet of red and black wire along with some pliers and some battery clamps. Once you have these materials together you can begin to successfully assemble your portable solar generator to provide you with an energy back-up.
The first step is to place the deep cycle battery into the battery box. Then use the red wire and battery clamps to connect the positive post of the battery to the positive output post on the battery box. Then use the pliers to clamp down on the battery clamps and ensure that they are secure on the positive posts of the battery and the battery box. Then use the black wire and the battery clamps to connect the negative post of the battery to the negative output post on the battery box. Now use the pliers to clamp down and secure the battery clamps on the negative posts of the battery and battery box. With this done the battery is now fitted for the solar generator to store energy.
Now as the second step, you will need to connect the positive and negative output wires of the 7 amp charge controller to the positive and negative posts on the battery box. This is to make sure that the charge controller is in line from the solar panel to prevent an overcharge of the battery. Next hook the positive and negative wires coming from the 15 watt solar panel into the positive and negative input points on the 7 amp charge controller. This secures the solar panel to the generator and prepares it to be used to generate power.
Now as the third and final step, you must connect the positive and negative wires of the DC power outlet to the positive and negative posts on the battery box. This is needed to provide a 12 volt power outlet for the solar generator. Following this connect the positive and negative wires coming from the 400 watt inverter to the positive and negative posts of the battery box. This secures the inverter to the generator and allows AC powered devices such as household lamps and small radios to be powered by the generator. At this point the construction of the solar generator is complete and it just needs to be charged with energy in order to be used.
In order to charge the generator, place the solar panel in an area where it can receive direct sunlight for about 4 to 8 hours. Allow the solar panel to sit in the sun for this length of time. As it does this it will provide an energy charge to the battery which the battery will store for later use. This generator with this set up provides enough energy on an 8 hour charge to provide power for 2 LED lights, a small fan and a laptop computer to be charged and operated for about 9 hours. Also you can use the generator to power a small electric hotplate for about 1 hour. While this is a limited source of energy in the event of a power outage it can provide a valuable source of green back-up energy that will still allow you to have some electricity where you otherwise wouldn’t.
