I agree that there are diminishing returns as well as increasing complexities with this sort of stuff.

Maybe for a simpler solution I could use one of my 2 kw aerosharp 93v transformers to drop the 240v feed to 147v into the water heater.

This will make the load around 1.4kw instead of 3.6kw

It will run for longer but maybe catch more excess solar throughout the day.

Any forseeable safety issues with this arrangement? I can't think of any.

Ultimately that might be a better idea instead of attempting to monitor everything.
