Ah, yes, I come at it from the boat angle, so I didn’t think of the grid-tie AIO inverter being the cheaper option! It might be less expensive, then, to simply add in a wind charge controller. There’s no issue with running two charge controllers in parallel to the same battery bank. They sense state-of-charge by voltage, so if one is running, the voltage is high and the other backs off. I think that makes the system slightly less effective, but probably not enough to notice.

Pardon if this is a naïve question, but the mention of hooking a turbine straight to the batteries makes me ask, why not just use a hybrid wind/solar charge controller?

Yep, punishment must be part of the deal, even if it costs us 3 times as much. This is how we know that, for conservatives, the cruelty is the point.

Hmm? The text says that a growth-obsessed economy will tip is into ecological disaster, which is true.
