Off the power grid

Here is a little video of how Doug maintains a power system at his cabin. It shows the solar panels and how they track the sun then on the generator house or bomb shelter however you look at it. In the generator house you will see a bank of 16 deep cycle marine batteries that get charged by the sun and/or one of the 4 generators he has. He currently has a 3000 watt power inverter to convert the 12 to 13.5 volts from the batteries into 120 volt power for all the appliances. That inverter isn't quite powerful enough to power some larger power tools so one of the generators still gets used pretty often. And in the winter months he may run one of the generators up to 10 hours a day to maintain power in the cabin when the sun is to low in the sky. The generator house took Doug years to construct as you will see in the video he built it with 18 inch thick walls to keep out the 50 below chill in the winter. One of the projects we will work on this summer is installing a wind turbine on the roof of his cabin to supplement the solar/generator power. There usually isn't much wind here but on the rare days when the wind does pick up it will be a great addition.

  1. 50 below, eh? Is your little cabin inhabitable in the winter?

  2. Hey Jared it's Jason M. Thank you so much for posting so many times on your blog. I have been following it and look forward to every new one. I have tried a few times to send texts, but I imagine your phone is no longer necessary. The latest video of the power grid is so cool. I can't believe how self sustained Doug's place is. Must be very cool to be able to stay there and work for him. I am very jealous of your adventures in Alaska so please keep the posts coming. Wish I could visit you. Did you mention you purchased "extra" bear protection? I know that was an old post. Stay safe. Mezzie
