Kevmo, I am thinking of installing solar. Although I am a degreed (two!) electrical engineer, I want to seek your expertise.
For the storage batteries, I want something with a high power density, right? I should not be concerned with amp-hours, right?
I tell ya what. Don’t worry about power density. When you put in your batteries & solar, the wires to & from them can be as thin as a hair, according to your understanding.
