To our knowledge, Living Energy Farm in the only community anywhere powered by a DC microgrid. Nintey percent of our electricity use is with daylight drive motors that run when the sun is out. We store energy in many forms other than electricity. Our DC Microgrid is cheaper than convetional off-grid design, dramatically more durable, and failproof. Our DC Microgrid is a layered, multilinear system (that's why it's failproof). There are a few photos here. The daylight drive equipment is also part of our DC Microgrid. (See separate photo gallery.)
We use computers as much as we want.
Our lights NEVER go out.
Each panel is a separate system.
