Planning help – integrating EcoFlow DPU + Smart Home Panel 2 with existing Tesla Solar (SDG&E NEM2)

Hey folks,
I’ve just picked up the EcoFlow Delta Pro Ultra (12 kWh) with the Smart Home Panel 2, and I’m now planning the integration with my existing 10 kW Tesla Solar (grid-tied, SDG&E, NEM2, TOU plan).

My goal setup is:

  • Daytime: Solar → power home loads → charge DPU → export remaining to grid for NEM credit
  • Evening (peak TOU): Run home from battery
  • Night (off-peak): Pull from grid if needed
  • Morning: Solar recharges battery again

I haven’t installed anything yet — I’m still in the planning and design phase. Before I start wiring or commissioning, I’d love to hear from those who’ve already done this or something similar:

🔹 How did you wire your SHP2 with an existing grid-tied solar inverter?
🔹 Did you keep your inverter grid-tied for NEM or reroute through EcoFlow?
🔹 Any issues with backfeed detection, neutral isolation, or CT placement?
🔹 What’s your software configuration (EcoFlow app modes, TOU scheduling, priority setup)?
🔹 Any practical lessons or “wish I’d known this before installing” advice?

I’m aiming for a clean setup that:

  • Keeps Tesla solar + NEM2 credits intact
  • Avoids any grid-backfeed errors
  • Maximizes self-consumption and TOU savings

If anyone’s willing to share photos, wiring diagrams, or screenshots, that’d be hugely appreciated.
Trying to get this right the first time before calling in an electrician.

Thanks in advance — this group has been a great resource for real-world setups.
