Hey All,
I came up with this solution - It may be entirely crap - please let me know where the problems are!
At one end Chinese brand 1.2kW 12V Vertical wind generator (supposedly) with suitable charge controller. (IE that is 100A max current theoretical!) Given that the whole unit was under $500 - I cant see that charge controller being adequate. Wind Generator Info
At the other End I want to connect this to one of the spare DC input lines of either my Fronius 4.0.1 Or Fronius Gen 24 - 6. The Input specs, the 4.01 requires 80V min, but Gen 24 will accept 65V DC, both up to 1000V. Max Cutoff Amps is 27 on the Fronius, so the trick will be keeping the peak voltage down to around 20A.
So the solution is basically this:
Wind turbine -> charge controller -> Intermediate storage 12V Deep Cycle battery -> DC-DC-boost controller (12V-->80V) -> Current protection -> Fronius DC Input.
The key is the booster converting the 12V DC to 80VDC acceptable to the Fronius input line, the trouble is controlling the input current. I cant see that the fronius would care how the DC is generated - it would normally be PV - but why would it care that it was any 80V input source?
Is this solution even close to viable?
