I’ve had these two Sol-Ark 12Ks sitting in my powerhouse for three years doing nothing, so I decided to put them to work. In this project, I’m pulling solar power from my mother-in-law’s 15K system nearly a thousand feet away and sending it up to my powerhouse through AC coupling. This setup also lets us run two different battery banks and start building our own microgrid. We’ll go over how the dual 12Ks share energy and how this connection ties two systems together to create a small family microgrid.
