Dogtown Farms basic 2 panel 2 battery 12 volt off grid solar installation powering aquaponics



Check out our sustainable, 100% organic backyard farm in South St. Louis City, Missouri. Dogtown Farms. https://www.facebook.com/DogtownFarm/?fref=ts

In this video I show how to install and connect a basic, 2 solar panel and 2 battery, 12 volt, off grid solar system with 2500 watt inverter.

There are a million different methods and sizes of solar installations, but I feel this is an excellent “beginner” setup that has worked well for us so far. We are able to run the aquaponics 400 gallon per hour water pump, as well as the small aerator for the 250 gallon pond.

2x 158 watt solar panels, 12 volt.

Pair of solar Mc4 Connectors/combiners

These “combine” the two positive cables coming off the 2 solar panels into ONE WIRE.

Everything simply snaps together.

15 foot solar extension cables to run from the ” MC4 branch connectors/combiners” to the solar charge controller

You strip the ends of the solar extension wire, and inser them into the “solar” inputs on the charge controller.

Of course everything on the charge controller is secured with little flat head screws.

These 10 AWG cables connect the output of the charge controller, which is labeled “battery”…to the LEAD 12 volt battery.

Of course all connections to the batteries are made using loops and galvanized steel nuts, bolts, and washers available at any hardware store.

Shorter 10 AWG cables to connect the LEAD battery to the SECOND BATTERY.

The inverter

————————————————-

Simply turn on the inverter, let it power up and tell you what voltage it’s running at, and then plug in a standard three prong cable to one of the outputs of the inverter. You simply run whatever device you need to run off that extension cable (assuming that there is enough charge in your batteries and the inverter is sized appropriately to the device.)
