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.
Build your own solar panel charge controller.
Purchase a charge controller and connect the panel to the controller making sure to connect the positive and negative correctly.
Hello friends today i am back with another project called diy automatic solar charge controller.
Current is flowing into the batteries at all times during solar power generation and it s possible for too much power to be shoved into the batteries possibly damaging them and even creating a safety hazard.
Divide the wattage of the solar panel by the voltage of the battery to get the number of amps your charge connector needs to handle.
The first thing the charge controller does is to prevent overcharging.
In the simplest of terms a solar charge controller regulates the power that is transferring from a solar panel to a battery.
Illuminating an exterior storage shack seemed like a good use for the panel so i set out to build the electronics around this.
Construction building your own solar battery charge controller is a relatively straightforward electronics project based on a printed circuit board.
Diy automatic solar charge controller.
In produce your own printed circuits i.
To charge a battery with a solar panel connect a charge connector to the solar panel.
I ve owned a small 5w 12v solar panel for a number of years.
Then run wires from the battery to the charge connector making sure to match the positive and negative poles.
It s a 555 based simple circui.
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.
Run the wires from the terminal block to the charge controller using color coded wire to keep track of the charges.
It s an automatic switching circuit that used to control the charging of a battery from solar panels or any other source.
There are two types of charge controller that meet this need.
