[RE-wrenches] Interfacing an Air 403 wind generator

I've grid tied a few battery based turbines now, both the 403 and Bergey XL1.
You can use a very small sealed battery (180 AH @ 24v), so that would take care of the maintenance issue.
Cost on the other hand doesn't make sense, unless they want some emergency backup  capability.
If they don't want backup, give them a trade-in on the AirX equipment towards a GT turbine.
