I am after some technical advice only please regarding an inverter to be connected with a 3KW wind turbine.
A free Power-One PVI-3.6-OUTD-UK which is a photovoltaic Grid Tied Inverter (out door) is available to me.
Please advise if that can be used to be connect the 3KW wind turbine (obviously after external rectifier , converting AC to DC)
This will be installed at a farm which also has grid connection. Please ignore any insurance or payment from grid rules etc.
I have looked at the current available models to see the input and output difference between PV and Wind models but can't figure out much difference.

Thanks

Novice, the hardware of ABB/Power-One's solar and wind inverters is identical. However, the firmware (software inside) is very different. Solar panels are a current source (you can vary the Voltage over a wide range, even short-circuit them, and they'll deliver just about the same current). A wind turbine is a Voltage source.

Doing MPPT (maximum power point tracking) for solar is completely different from the way it is done for wind; Solar PV inverters simply sweep the Voltage range looking for maximum power, wind inverters have a table (MPPT table) that they use for looking up what load (output power) to put on the turbine for a giving input Voltage.

Using a solar inverter for wind is bound to end in disappointment. You need a wind inverter.
