Proven Wind Turbine

[jason121]

Does anyone know anything about these wind turbines. I have one which is off grid and would like to attach it to a on grid inverter, would there be an issue in doing this

The company went bust and the assets were purchased by Kingspan renewables in 2011. It now trades as Kingspan Wind. They could be a good place to start.

It depends which model of Proven it is. Some of the old off-grid models were only 48V so it will be difficult to find a matching grid-tie inverter. The 2.5kW and 6kW grid-tie versions generate a fluctuating 200-600V wild 3-phase AC (varying with blade rpm) so need a rectifier before feeding DC to a grid-tie inverter.

I have the 6kW grid-tie version.

These are 2.5kw, one of them he is selling the other one, he wants to grid tied.

You will need to find out what its output voltage level is. Is it charging batteries or connected to an electric heating system?

 

[jason121]

charging batteries at the moment

It is possible to have the generator core changed to a grid tie (nom 300V wild AC) version. As above, then rectifier, then Windy Boy inverter to grid tie. Certainly worth speaking to Kingspan Wind about this to see if they will carry this out on a Proven machine.

I have the manual WT2500. 3Phase output @ 30v 90amp (60A/ph) for 24v system and 60v max 45amp (30a/ph) for 48v. Any ideas
