Our Electrical System

Tiny Tack House solar panels

Hey everyone, Chris here. We frequently get questions about the electrical system of the Tiny Tack House, so I have decided to do a post about it :)

I would like to begin by recommending the same thing Dee Williams says in all of her workshops..."If you don't know the code, don't do the work". This is especially important with something that can be potentially deadly like power!  We worked with Whidbey Sun and Wind to assist with the planning and ordering of our equipment. I had an electrician verify my work to ensure I connected everything correctly.

The equipment we chose to install is as follows:

• 4x AUO Solar - 255 watt PV modules
• Outback FLEXPower ONE-2
• 4x Full River DC260 12V Sealed AGM Batteries and Cables
• SunWize T-4X8D Battery Closure (aka “the cooler”)
• Unirac SolarMount rack system

​Inverter box and battery box

This is pretty much how our system is set up

​We built a box on the tongue of the trailer...be careful not to build too far out as it may affect your turning radius! On the right side of the house, you can see the battery box.

​OutBack Power FP1-2

​Breaker Box to Inverter

​We can hook up to either a 15 Amp (standard extension cord) or 30 Amp (RV) hookup

​Each of these 4 sealed lead acid batteries weigh 172 pounds!
