Hey everyone! I'm in the process of putting up a DIY 10kw solar array with an 8kw Sol-ark inverter and 20kwh of battery storage. The batteries are primarily for use of peak shaving, and our grid is reliable (99.95%). However, I would love to keep power going in the house during grid downtime...

Hi everyone! I still kind of feel new to the solar industry despite doing tons and tons of research over the years and am getting close to pulling the trigger on a system, new or used is still unknown. I'm wondering while I'm researching different inverters for future growth: if I get 2...

Hey everyone! I've been playing with the idea of going solar for the past few years off and on, and now that I'm going to move to an area where solar is allowed I'm excited to take the plunge soon! That being said, I feel like I've "configured" so many systems in my free time that I'm confusing...
