The green wire goes directly to your ships main earth ground point. On most boats this is the engine. On many boats a keel boat is not a sufficient earth ground due to encapsulation or barrier coating. The green wire from the wind gen is your safety earthing wire.

Simon is correct. Keelbolts can be part of a lightning ground but not an electrical ground.

Join the green to the black and wire up as normal.

About to put in wind generator where to connect green ground wire?
Am about to install my Air X marine generator on the transom of my Pearson 10M. There are 3 wires on the wind generator - am going to run the positive and negatives to my house battery with a short circuit switch to stop the blades in case of extreme winds etc. Can I just connect the green ground to say a ground on my keelbolts? Was reading that keelbolts are used as grounds but I wonder if that might be a bad idea as it could cause them to corrode faster? Otherwise where would be a good place to connect the green ground wire?
