I bet you’ve seen a lot of those solar kits and products out there, there’s a bunch of them. Of course, I believe that Power4Patriots is the best possible system for really breaking the shackles of the power company and truly becoming independent.
The reason I believe that is that none of those other kits actually tell you how to wire the system together (plus not one of those guys actually live with off the grid, or even on solar, like I do). In fact they seem to gloss right over the most important part of the system: how to tie it all together.
That’s why you have me. In this video my friend and fellow off-grid patriot Kriss walks you through how he completely wired his system together: solar panel array, disconnects, batteries, charge controller, inverter and backup generator. He ties it all together.

Its critically important to understand how all this goes together. A lot of people struggle with why we wire things in series and parallel. The theory is simple: wiring things in parallel keeps voltage constant, but adds amperage; wiring things in series keeps amperage constant but adds voltage.
Often times in wiring solar power systems we need to keep the voltage constant: say when going from the 24V battery bank to the 24V inverter. So we can wire things in parallel to keep this voltage constant.
Other times we want to add up voltage. We do this often with the solar array itself, also with wiring a solar panel together with solar cells. Higher voltage travels through wiring more efficiently, losing less voltage along the way (given that the size of the wire is sufficient). So often times we will wire solar panels, and solar cells, in series to get that voltage as high as possible.
After we do this we often have to knock that voltage down so that we can wire it to a 24 or 48-volt battery bank. We can do this with a special charge controller called an MPPT controller. This will allow us to have a 100V solar panel array, and 24-volt battery bank.
I hope this is helpful in understanding how we put these systems together. Stay tuned for more on solar panel systems.
