No it's not. Bung it across the mains and it will sync *very* quickly,
probably to the detriment of part of your kit though depending on how far
out you are. B-)

Commercial boxes can be bought that do everything but these small
turbines generate so little power that that expense probably isn't
justified. So you then either have a LV battery supply and distribution
or some seperate mains via an invertor to seperate mains distribution.

Also the control box needs to fail safe. It *must* disconnect your
generated power from the mains when the mains fails but if you are
feeding the mains how does it know that the mains has failed?
