	1 - off 15 kW wind turbine 120 meters from the 3 - off 6kW inverters ( cable 16mm ) distance between inverters and the transformer on the pole is 35meters, existing cable 25mm is this cable ok

	Turbine voltage. Inverters 1Ph, 3Ph, voltage, give us a clue. Rule 75 __________________ The reports of my death are greatly exaggerated.

	Proposed installation of a 15kW / 300 V single phase wind turbine. Turbine located 130 meters from Grid Connect Controller, Inverters ( 3-off WB 6000 ) 240V etc, cable size 16mm Distance from Inverters to pole mounted 15kVA transformer is 35 meters, existing cable 25mm

	Hi there, having looked at your specification and can see the WB 6000a grid connected inverter has a nominal operating voltage of 275 Volts dc to operate, as this unit has an input range of 246 to 600 volts. This would not allow your system to be as efficient as it could be. You may require more inverters of a lower operating voltage to match you turbines 300 volt maximum output. If you check these details are correct i will endeavour to do your calcs using British Standard Calculations, ie volt drops designed for calculating in metres and not feet.
