Thanks Alan, seems I am trying to do the impossible! the reason for keeping it small was two fold, 1:- I just wanted to send a small amount of single phase surplus power from my battery into the existing house single phase electrical system and, at 24/7 operation this would release in the order of 360 kW per year
2:- I had in mind to use a constant natural water supply, by adding a tiny hydro system of similar size and type, again supplying electricity to the house.
From what you have said, it seems that this is simply not possible to do with a single phase motor and so the project unfortunately stops here, not a happy chappy, but thanks for explaining
Best regards Robert
