Скачать или смотреть Energy Builds: 4K-SF Home, Solar Panels Go Live (EG4 FlexBOSS21) – Part 2

In Part 2 of this Energy Builds project, we move to the roof and bring the system to life. We install the solar array on a 4,000-square-foot home using IronRidge racking, Tigo optimizers, and 430W bifacial panels, then commission the system and watch it start producing real power.

This video covers the full rooftop workflow: layout, mounting, rail install, optimizer placement, panel wiring, PV disconnects, and final commissioning into the EG4 FlexBOSS21 and EG4 GridBOSS system. If you’re trying to understand how a modern DIY solar install actually comes together (from roof to inverter) this is the step-by-step process.

👉 If you haven’t watched Part 1 yet, start there first. That’s where we cover the inverter, batteries, GridBOSS, and system planning.
