Small inverters

[stephen]

Will the new inverters (currently under test) take 3 phase same as the windy boy or will they be energised with 24/48v wind turbine and step up to 240v.
I ask question as we have a small Lister CS pumping away and wondered if this too could be connected to the system. I am happy to change the alternator or strip the head from another wind turbine and spin that through the lister if i can get the speeds matched.
Is the new invertor G83 complient or does it just match the phase of the incoming power and Isolates itself if grid power goes down.

Thanks in advance

Stephen.

Good news - the sample small dutch grid-tie inverters should be arriving in the next week or so! At the moment it is not G83-compliant (it has only just been produced) - but we are hoping to get it certified once we have tested it thoroughly.

As far as I know they take a rectified DC input, so you could use an ac or dc source. You might need to use some smoothing capacitors if you use a standard alternator if the frequency is low (wind turbines tend to be quite high frequency due to the number of poles in the alternator, so ripple voltage on rectified output tends to be quite low).

The lister CS is a great machine. I have a CS-6, which I am hopefully going to grid-connect during the autumn. I am planning to make it even easier, by using a wind turbine alternator to provide the input power to the grid-connect inverter (see one of the other topics on our forum - CHP-diesel generators)

Thanks Ivan,
I intend to do the same as your small lister CHP its only a small modification.
I have sent an order to Naviton and asked to be put on the waiting list for possibly 2 invertors.

Thanks again
