We’re planning a system that ties together
- 15.99 kW Enphase IQ8+ array
- Two EG4 14.3 kWh batteries
- Whole-home generator
- Either EG4 12000XP + GridBOSS (we already have a 12000XP in stock)
- OR EG4 FlexBOSS + GridBOSS
Goals:
- Enphase as primary daytime source
- Charge EG4 batteries from excess PV
- Keep grid export close to zero
- Integrate generator for extended outages
Question: For this kind of setup, would you recommend sticking with the 12000XP + GridBOSS, or going with FlexBOSS + GridBOSS (or something else entirely)?
We’d love to hear from anyone who has installed similar systems — especially around Enphase re-sync in backup mode, generator wiring, and overall ease of install. Any advice, lessons learned, or recommendations would be awesome
