I know this was posted a while ago, but I would be very interested in what you learned. There is also the
Aerovironment USPC-5000 (and smaller USPC-2000)
but it looks like it costs in the range of $5500! I have not found any competing products, but it looks like it is some specialized kind of VFD (voltage frequency drive, ac drive). I have no experience with these devices, but understand that they rectify ac->dc and then use pwm (pulse width modulation) to convert the dc back to ac at varying frequencies. I want to combine the output from a number of wind turbines (each 4m rotors) to power a large (5kw) standard water pump. Is it possible to access the dc (bus?) in the vfd directly?
I would very much appreciate hearing what you discovered.
