I can't claim to be living "remotely", although anybody who drives from Calgary to my acreage in the country thinks I do. This step makes my barn "off grid" power.
Having located the new barn on the best spot, it was obvious that giving it electrical power from the utility would mean a Lonnnng trench and run of wire. The utility pole is 300 feet away, and the wire would have to go around the house if it connected to the utility service directly. The alternative, tying it into the house, would require an electrical modification in the house - where there are no available circuits in the panel.
Well I never intended for my hobby to provide this kind of solution, but frankly it has just paid for itself. Every penny. Around Calgary, these days, contractor's rates for digging a 300 ft trench and putting in a 50 Amp service to that barn would run me about 8-10,000 dollars. I haven't yet spent 6, between the tower, inverter, wiring, and controls.
I buried the wire from my battery shed to the barn on labour day weekend (I think americans call it something else and in the UK they don't even get a bank holiday early in september). It took me a fair bit of time to sort out the wiring business with the inverter because the cables and amperages are so large. It's a Xantrex 4024, requiring OO cables and an appropriately sized fuse.
With the wire laid in, and the inverter finally mounted in the shed, I just needed to go to the electrical wholesaler's store and pick up standard boxes, breakers and wire. Ahh familiar territory. And here's the result:
