You are sorted Mike

What sort of daily kwh are you getting from the turbine.

Split the DB to run the stove, geyser (if not solar) and other heavy users directly from the grid. Then get a 3KW infini or rebranded infini for between about 12K and 17K IIRC. It is a true hybrid which can normally supply 3KW and can combine the grid to supply loads of more than 6KW for extended periods, like when the vacuum cleaner, hair dryer and a few other items are used simultaneously. Add up to 4500W of PV panels and a decent battery bank, e.g. 8 x Trojan T105-REs and you have a reasonably cheap set-up which should work seamlessly once configured correctly.
