DIY Charge Controller

A reasonably priced and reliable “Diversion Load” Do-It-Yourself Charge Controller for use with your PMA’s or solar panels.

This circuit can be built for about $12.00!

Controller_Tmplt_07G2E has hired a team of electronic professionals to design a Do-It-Yourself charge controller. The nice thing about this is we were able to specify all the
features we wanted and make sure the plans were full of good information that you could use to build your own controller. Let me tell you a bit about our plans and the features we have put into our control circuit.


First of all we requested that the DIY plans would result in a savings of money. The components for the circuit itself come out to under $20. If you decide to add in all the fancy Diodes and Dummy Loads it will raise the cost but you can do that in stages.
Second… We requested that it be fairly simple but hard enough to be a fun project for the true Do-It-Yourselfer! And they did! Its a pretty simple circuit, but does take some skill with a soldering iron and basic electronics knowledge.
Thirdly (is that a word?) we wanted it to be upgradeable. Sometimes you just want to get up and running and
don’t always have the money to buy all the fancy stuff. Our plans will show you how to build your controlling circuit in stages.
And last but not least we wanted it to be safe. There are several safety circuits and measures designed into our DIY charge controller.


We are very proud of this circuit and hope you all have fun building this DIY charge controller! Not long ago I was in your shoes… I was looking for information about wind & solar power. I struggled to find all the info I needed. I spent money on several DIY products trying to get answers. And there are several good ones out there however, they ALL fall short with the simplest information. So I have made sure to include details about everything, so you are not left hanging and searching Google for an answer to say… the pin out to a
relay, or ever what a relay is?


 Our DIY Charge Controller plans will include:

Full detailed schematic of the charging circuit.
Circuit board layout.
Complete parts list and locations on the net to purchase those parts.
Information on how to build your charging system in steps.
Full color pictures of the process.
Diagrams and information on some of the more technical aspects.
