The "Grid Defection" movement is here. But for most homeowners, the barrier to entry isn't desire—it's installation.
The Tesla Powerwall 3 is a masterpiece of engineering, but it comes with two fatal flaws: a massive backlog (6-9 month wait times in some regions) and a requirement for professional, permitted installation that can cost as much as the battery itself.
Enter the Modular Challenger
The EcoFlow Delta Pro represents a shift in energy architecture. It decouples the battery from the building. You don't "install" it; you just plug it in.
Quick Verdict
If you own your home forever and have $15k to spend, get the Tesla Powerwall.
If you want immediate backup power that you can take with you if you move (or use in an RV), buy the EcoFlow Delta Pro.
The Math: Cost Per kWh
When you factor in the "hidden" installation costs of hardwired systems, the price gap widens significantly.
- Tesla Powerwall: ~$11,500 installed (13.5 kWh)
- EcoFlow Delta Pro (x2): ~$6,200 (7.2 kWh, expandable to 25kWh)
