Hi Mex,
I hope the tooth fairy will ease your pain.
I find that switching is fast enough on the Sola Basic that voltage jumps up before the air conditioner compressor motor makes a sound and before the fan has even started to turn. I was pleasantly surprised that was the case.
Obviously, the Sola cannot deal with millisecond voltage excursions, which is why I want to do some surge suppression.

3. A weak point in stepped MEXICAN autoformer voltage control, is it takes time for the device to switch from one step to the next. Sudden line surges can raise (or lower) voltage by the percentage of boost (or sag) built into the transformer switching system. The switching has to have hysterisis to prevent stitching chattering.
