Thanks for the reply guys.

Currently we are planning the build but the solar system will be very similar to what we currently have being a 3kw grid tied SMA system. I am using EmonCMS and openenergymonitor CT hardware to monitor power produced and our grid import / export. Im currently using a diverter that measures the grid connection and runs an immersion heater to heat our water in a tank. (some kind of leading or trailing phase power control to "throttle" the resistive load)

Im pretty happy modifying / hacking things to a point. Ideally I could find a common compressor that is 3 phase an can be run with a 1 phase to 3 phase VFD or a "mini split" outdoor heat pump that I could add a heat exchanger to heat water and use the existing inbuilt inverter in the unit and talk to it via the existing controls that would have been attached to the indoor unit?

I dont understand why this is a new problem? Surely in hot environments people have solar installed and want to match the output of AC to the power produced?

Thanks for taking your time and replying to my thread.
