Build Your Own Solar Panel Charge Controller

Illuminating an exterior storage shack seemed like a good use for the panel so i set out to build the electronics around this.

Build your own solar panel charge controller.

It s a 555 based simple circui. There are two types of charge controller that meet this need. The first thing the charge controller does is to prevent overcharging. Hello friends today i am back with another project called diy automatic solar charge controller.

Purchase a charge controller and connect the panel to the controller making sure to connect the positive and negative correctly. It s important to use a charge controller as it improves the efficiency of a solar powered system by up to 50 can prevent the batteries from being overcharged and will extend the battery s life when used correctly. Diy automatic solar charge controller. So i saved a large portion by building my own solar system since a commercial solar panel would have cost 400 on up for just the solar panel itself.

When i lived in an apartment there was little use for it but once i moved into a house i started thinking of practical uses for it. In produce your own printed circuits i.

Then run wires from the battery to the charge connector making sure to match the positive and negative poles. It s an automatic switching circuit that used to control the charging of a battery from solar panels or any other source.
