The inverter I installed in 2020 was limited to 6000 watts output, not enough to reach the minimum specification for Level II charging, 7500 watts. Also, it had some problems starting with the charging loads. I often had to start the charge at lower rate and adjust the rate upwards to something like 5000 watts. Workable, but something better would be nice.

Continue reading →After we bought the Hyundai Ioniq5 electric vehicle, we needed a charging system at the ranch. A recommendation from a friend and my own research led to the Emporia Classic EV Charger.
Continue reading →I’ve made about 20 posts regarding my adventures in Solar Energy. They all lead to a Solar-powered “Gas Station” for an Electric Vehicle (EV). As prices for solar equipment have come down, the idea is within reach on my budget.

The Lithium Iron Phosphate (LiFePo) cells I was using had been in storage for a while and though new, would need a some maintenance. There would be 64 of them, arranged in 16 sets of four cells.
Continue reading →After building a wooden enclosure for the Lithium Ion Solar Battery, it was time to think about copper bus bars to connect all those cells together. This requires a little math, since the bus bars have to be big enough to handle current demand, but not too big — copper is expensive!
Continue reading →The first step in building a really big lithium ion solar battery is the enclosure. At a minimum, it will hold 64 of the LiFePo4 cells and support their weight; about 325 lbs. It also occurred to me having some mobility would be nice.
Continue reading →The next upgrade for our Solar Power System was a Really Big Lithium Ion Battery (RBB). When we first installed the system in 2020, I didn’t have a cost-effective solution for Lithium Ion (LiFePo4 chemistry). That came later with the acquisition of a lot of LiFePo4 cells. Since then, I’ve built two small batteries to get used to the technology; one as a portable solar generator, and a slightly larger one to power the ham shack. With those under my belt, it’s time to tackle a 48-volt battery to replace the existing lead acid batteries.
Continue reading →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.
Continue reading →Just before disassembling the Thomas Transistor organ to create a VPO, I tried turning it on for one last listen. I wanted to sample a few of the basic sounds for later use building a sample set or synthesizer patches. It hadn’t been used for quite some time, though I had no reason to suspect it wouldn’t work. Within a second or two of powering the organ, there was a loud pop, followed by a very loud hum. Time to get it on the bench!
