One of the dreams here at Roy Creek Ranch has been to add Solar powered heating and cooling (HVAC). We’re now producing substantial power from our solar array, and it would be nice to use that power as much as possible. Also, for those times when the grid fails, some heating and cooling will keep us more comfortable and maybe even a little safer in extreme weather.

The “ThunderSky Winston” cells had come from a Segway repair operation and were new. A little looking around the ‘net revealed they were still available from GWL Group. With a capacity of 60 Amp Hours (AH) and nominal voltage of 3.3 volts, they looked useful for building a 12-volt Solar Generator.

In particular, a recent upgrade to the battery and inverter system significantly improved our resilience during … Continue reading →
Upgrading a Solar Power System It was time to upgrade the solar power system installed for the shop almost two years ago. I’ve been happy with original system, but it needed expansion as soon as funding permitted. I also wanted … Continue reading →
With summer on the way, and an end to our rainy season approaching, I am reminded of the dry summer last year and concerns about the water table here at the ranch. Fortunately, our water well performed during the last year’s drought, but a number of our neighbors had trouble with their wells. Some troubles were resolved by a visit from the well-service company and a replacement part of two, but at least one well’s water level was low — resulting in low or no water output.

A quick test showed the expected 240 VAC at the inverter output, and it was time to connect it to the breaker panel in the shop.

The array is about 50 feet from my shop, where the batteries and inverter are located. I planned to use two strands of #6 UF direct-bury cable to conduct the predicted maximum of 36 amperes to the shop.
