Allan,
I'm trying to do the same as you (but in NW Scotland) and have bought the following kit:
Navitron 750W high head turbine
REUK 600V bridge rectifier
SMA Windy Boy grid tie inverter
As Ivan says the DC out of the rectifier isn't smooth enough so you need a smoothing capacitor between the rectifier and the Windy Boy.
According to the reading that I've done an electrolytic capacitor rated at least 400V and 1200 microFarads will do the job for me. You might need more Farads as you are generating 1kW (see
http://www.kpsec.freeuk.com/powersup.htm#bridgerectifier - scroll down for the 'Smoothing' bit).
You might have to consider going for the 1700W inverter.
The 1100W model recommends a maximum generator output of 800W for 5000 hours/year. I hope to be generating 750W for 70% of the year, which is 6000 hours.
The 1700W model is 1240W for 5000 hrs/yr, which is probably more suitable for your 1kW machine.
Ivan,
You talk about 'a bank of capacitors' - can you explain why more than one and how we should be sizing them (or it)?
Cheers,
Malcolm
