Build your full EcoFlow system
Vendor-locked configuration — only components EcoFlow themselves sells as compatible. We don't suggest cross-brand mixes that the manufacturer doesn't bless.

Why we don't suggest cross-brand mixing: connecting an EcoFlow battery to a different-brand unit isn't supported by either manufacturer's warranty, and the BMS protocols don't speak to each other. We only configure within a single brand's blessed ecosystem. If you want to mix brands, that's an intentional DIY choice — and you'll want a different tool than this one.

RV note: The DELTA 2 Max has a native TT-30R outlet — a standard 30A RV plugs in directly, no L14-30 adapter needed. For 50A RVs you'd add a TT-30 → 14-50 adapter (~$35) but you'll only get 120V on each leg, not split 240V.

Skip if: you'll use the DELTA 2 Max with extension cords or unplug-and-plug into appliances directly. Add if: you want a hardwired path to a transfer-switched 120V subpanel covering specific circuits (furnace, lights, refrigerator).
