BTW, Klunker, 20K BTU/hr for a 2800 sq ft house is pretty impressive. Is that your expected peak load?  How cold does it get in your area?

At any rate, you must have an incredibly well sealed and insulated house.

yes, thats peak load.
8" neopor sip walls with and an additional 1" of foam on the outside.
So what about R35-38 walls and R60 ceiling, R24 on basement walls and under basement floor.
Triple pane Fiberglas windows R5.5.
we get about a week or two of subzero weather usually during the winter, I'd say the ave. temps in Jan . are around 10-20 deg F.

The system I posted about back on April, 17 of 2016 is at my sugarhouse. I now have added another system at my home. There I am completely isolated from the grid (the solar, not the home). I put in 1710 watts of panels (6@285W each). The power enters the home thru a basement wall. In there I have an MPPT charge controller, an 3524 Outback inverter and the energy is stored in a 24V Rolls battery bank at 683 AH. I started back in June, but didn't finish in time. When I started NY State had not yet adopted the 2014 NEC. I thought I was finished on Oct. 18, 2016. However I then discovered that NY had adopted the 2014 NEC effective 10/3/16. As such, my final inspectiohn then required me to conform to the new code, specifically relating to "Rapid Shut Down" requirements. A good idea, but one that cost me $2500 additional. All solar systems, both grid tied (they had to since the 2011 NEC) and off grid required a "rapid Shut down" feature. In case of any emergency, fire or other, first responders must have a single point shutdown control to shut off all power in the system, it must break power from the panels, and the charge controller, the inverter and the battery bank. Those controls are far pricier that the simple shut off switch required under previous NEC codes (but are much safer for firemen and other first responders). In my situation I needed 4 points that shut down the entire system, one at the location of my electric grid meter, one within 10' of the solar panels, one within 10' of where the power enters the home and 1 near the panel board where the charge controller, inverter and close to where the battery bank is.

Darrell,

PM me if you are interested. I recently went to a Solar presentation there in town put on by individuals. A few people doing it and a few of us just starting research. Really good folks in your neighborhood. I'm in K-Falls & Chiloquin so we're close.

If I can help get you to people who might be able to help that have a good handshake.
