very inspiring. The biggest disadvantage of wind power is it is not consistent. This is also problem for heat storage discussed here. Using surplus power to heat water is a good solution. I suppose the water quantity should also be controlled automatically. Water can evaperate. If the water drop to ...

looks like fansinating. But the website does not provide rated power. 7.4kw at 14m/s, 4.2KW at 11m/s is a too ambiguous. Probably desigened for 6KW. If so, 14m/s as cut-out speed is too lower, meaning more energy unable to be absorbed if wind is good. Not very suitable for Scotland areas. And the pr...

thks very much. I think I should contact my DNO first now. My targeted inverter seems to be equipped with all necessary functions.

Make a try now.

Thanks Janco2, is your wind boy 6000A 's G83 certificated is issued by SMA itself? That's too expensive for me. And the turbine i am planning to buy is already equipped with a griedtied inverter. But not sure if its G83 certificate is acceptable. We have a grid connected 6kW wind turbine. To enable ...

Thanks alot. Adam2,

Do you mean that G83 certificate is ok for self declcared? If so, there is risk.

Ofcourse, I'd like to buy a SMA inverter, sth like that. But that's too expensive, nearly half of the turbine cost, not economical.

I plan to install a 5kw wind turbine for grid connection. I heard that the inverter needs to comply with G83/1 regulation. The seller shows me one. But I found it is issued by the manufacturer on its own. Is this ok? I suppose it should be tested by a third party, some certified body, right? Come by...
