Not really had any experience of renewable energy sources but been asked to install 2 of 3 phase boards for a farm which is having 2 of 11Kw 3 phase wind turbines. 1 phase will eventually supply new house, other to supply existing temporary caravans and barn conversion and the last phase will supply the other new house when the old farmhouse is demolished. Caravan supply will be removed when house built. Customer is concerned about balancing the load. From what I gather what is generated and not used on site will be fed back into the grid. So if the house is off 1 phase, other 2 phases will not be connected as of yet and what they produce is fed back in. Will this unbalanced load effect the turbines or will the electronic controls be able to cope with this. Am I right in the other 2 unconnected phases producing electric will be money for the customer.
