Some people may not know what off-the-grid or off-grid means, so here it is --- The term off-the-grid or off-grid refers to living in a self-sufficient manner without reliance on one or more public utilities.

Off-grid living is no longer a one room log cabin in the woods. It's energy independency. You don't have to rely on utility companies, you create your own power. Today, there are more than 180,000 off-grid homes in the US.

Off-Grid Power {Inverter}…

40 degrees - 9:47 am - light wind and rain...

"power center"
The inverter system, sometimes called the “power center”, is the most important part of the off-grid power system.  The power center contains all the gear that converts DC electricity produced by solar panels, wind turbines, hydro systems or generators into useable 120 or 240 volt AC power and directs it into the home.

The combo of inverter(s), charge controller(s) and safety components is responsible for running our off-grid power system.  That simple reason is why we have been doing so much research on inverters.  We want to find the best “power center” that fits our budget and needs.

After several months of research we finally decided to go with the MS-PAE Series Inverter/Chargers made by Magnum Energy.  Magnum Energy, based in the state of Washington, has been blazing a new trail through the off-grid industry since 2003.  Their products rival the leading competitors as far as quality with a more user-friendly interface, simple design and a better price.

Magnum MS-4448PAE
We are looking at the MS-PAE, which is a pure sinewave inverter designed specifically for the most demanding renewable energy applications.  The unique design of the MS-AE Series provides two 120VAC output lines that are 180 degree out-of-phase with each other, so that the combination of the L1 and L2 lines total 240VAC and the voltage between either L1 and L2 and neutral is 120VAC, eliminating the need to purchase two units and stack them together to get 240 volts.

Now that we have done our research, watched a chunk of money go bye-bye as we placed the order, it is now time to wait in anticipation for the big heavy box to arrive in the mail!  Thank goodness for free shipping; otherwise we would have been taking a little road trip to central Oregon to pick it up.
