Multiple tubines make up my system and they seem to function erratically. Why?
Check your wire sizes to be sure they are at least as big as those specified in your AIR-X marine manual (bigger is always better, but more expensive.) Be sure all of your wire connections are very solid, have no gaps, have no corrosion, and no crimp terminals are used. If your turbines are at various distances from the batteries, make sure turbines with longer wire runs have bigger wires. There will be some variation at what voltage turbines will enter into regulation based on the relative wind to which each turbine is exposed. Small differences in line loss can be significant in strong winds.
