Hi! I am new to this and interested in getting a solar-windsystem running, while we've already got a solar panel installed (320W) on a 12V battery system. I'd love to add a 400W wind turbine. As I might wanna upgrade the system later on to a 24V battery system when it's getting bigger, the gib question now is if we should go with a 12V or 24V 400W wind turbine.
In both cases, this MPPT controller would be able to feed a 12V battery, wouldn't it?
And if we'd upgrade later, would it feed a 24V battery?
