[RE-wrenches] Xantrex XW system stability

[Kevin Pegg]

Hi Jay, 

That's a good idea. No reason why the CC's need to be tied to the inverters, so could segment the system. 

The solar is visually impressive, but functionally near useless as there's just not much sun up at the north pole. An engineer who has never successfully deployed solar designed it like that.

Hi Kevin

Given how that system works, could you install the CC's on their own?

Ie use a seperate scp to keep track of data?
