Its calm, and translucent cloudy. Nice for taking a break from work.
I just thought pushing up a cup for awhile would be ticklish. Its been so rainy and cold here.
A postscript denoting the progress made concerning water... I installed the 2500W inverter with an earth ground and the 1/2HP Myers 2NFL51-12 pump. The pump causes the inverter to trip just before starting and running normally on 10 amps. I also used a starting capacitor wired across the inductive pump load. Thus I am in process locating and pricing a similar pump that yeilds lower capacity (about 5 GPM.) Doing significantly less work the motor should require less power to start. I have found a couple pumps on Ebay in 500 dollar range that are optimal 1/3 HP 5GPM pumps. They will run on just 7 AMP after starting. Its like a conspiracy prevents my buying a low capacity pump to run on a low-cost inverter.
Its time to ground the stove and gas lines for safety against lightning. With the new inverter I find that the microwave is working much better, cooking potatoes in the same time as it did in my last house. With the cheaper 750W inverter the microwave was noticeably less efficient, barely cooking food. The new inverter is also quieter since it does not require a fan except when providing near full capacity power.
I like to work on these problems looking for the low-cost solution. In the case of the off-grid water well, its possible to do it more expensively with advertised solutions that cost allot more than $225 for the inverter and $400 for the pump. Until recently we were seeing 5Kw gas generators at nearly $1000. I might be able to market a power backup solution for $3,000 that would include the 800W Wind Generator, 1.5Kw Gas Generator, Battery Chargers, batteries, 4" deep well water pump, 2500W modified sinewave Inverter. Retail on this package is $1895. Add a charger and 400W of solar panels to total $4000 retail. Installation would be 1,000 roughly to net something for profit. With dealer costs the profit could be better, adding something like $1500. My low-power solution does not address refrigeration issues which can vary depending on preferences. Personally I find it practical to eliminate refrigeration and isolate the rest of the solution that does not require continuous power. Finally I imaginge I could be looking at refrigeration in the basement with a super-insulated container and AC powered unit. A an alarm might signal when temperature is too high and power is absent. The unit could cool during daily charging periods and idle much more than a common refrigerator. Size, materials and ambient room temperature all contribute to energy efficiency.
Adding electricity to the remote cabin is not horribly expensive without the need to run a standard refrigerator. I have seen a 300W full-size model. Price has driven the full-size feature into the design. Paying 1000 dollars for a half-size unit is seen as impractical compared to similar prices for full size. With styrofoam I would think its possible to improve a cheap small size model to make it keep things cool for 150W daily (12 18W sessions would run a 150W compressor just 8 minutes and 20 seconds. Does it sound possible? I think so. This energy level fits into my present realm. 150W daily compares to 1000W or more on standard models. High efficiency models might use 350W.) I'm trying it on a low budget a-step-at-a-time.
