Perhaps more investment in automated load management is the answer? The technology to make it happen (for example, Raspberry Pi or ESP32) is dirt cheap. Likewise, thermal storage for HVAC is also...

Definitely time for a better soldering iron. Something like the TS-100 will handle 12AWG wires with ease. It uses integrated heater cartridges with better coupling than the older irons that merely...

You use the contactor (a very heavy duty relay) to switch the water heater, then you use a smart plug to switch the contactor. Not having an outlet nearby makes things slightly more complex, really...

Go with good quality (e.g. Kester) 63/37 leaded solder. Lead free is harder to work with so I do not recommend it for a beginner. For the iron, go for the TS100 if you want one that's portable or a...

Interesting new take on a window A/C

About the only features that seem to be missing are heat pump operation and infrared tracking to automatically direct airflow where needed.

I got a lot more parts for the inverter (the inverter module itself, capacitor bank, inductor cores, various control circuit parts) and I'm working on it. It will be a long project for sure, one with...

No, the inverter works by sourcing a current to offset the load current, more like "blending" than "switching". For example, if the load is drawing 10A, the inverter will supply 10A to offset it. (In...

PV inverter from Prius inverter
I'm looking to build a bigger solar power system, with thermal storage. Since going full grid tie is a bit involved, I'm planning to make it "zero export" with limited battery storage instead....

Just build a dual comparator circuit with one output to trigger around 3.15V and another around 3.45V. That will give an easy indication of low and high charge. If you want more accuracy, you'll have...
