[QUOTE="ProDave, post: 255487, member: 6969"] Experiment step 1 results: I've found the "big" auto transformer I knew I had and hooked it up to my immersion heater. Here's the measurements: Input: 247V @ 2.6A = 642W Output: 110V @ 6.3A = 693W So clearly one of those measurements was inaccurate but it shows my rough calculations of approximately 687W to be close to the mark. The only "problem" is the "big" auto tranny I had turns out to only be rated at 500VA. A short (half hour) test didn't show any problems with the tranny. But today is a dank overcast day and the panels are not generating much. So next sunny day we get when I'm at home, I'll turn the heater on and give it a prolonged test, firstly to see if I can get away with that transformer, and secondly to see if it results in a useful heat input to the hot water tank. I've also registered my interest with RS to get on the waiting list for a Raspberry Pi. (what's the fascination with calling electronic stuff after foods. Did anyone see the Ronnie Corbett sketch about that?) [/QUOTE]
