EcoFlow DELTA Pro Ultra
EcoFlow's modular whole-home flagship: a 7200W inverter head that stacks up to 15 batteries for 90kWh, or triples to 21.6kW output. Price shown is the inverter + one 6.1kWh battery; the Smart Home Panel 2 (roughly $1,500-1,900 more plus electrician) is what unlocks the automatic 10-circuit backup owners actually buy this for. Owner sentiment is mostly awe at capability with recurring gripes about the ecosystem tax - every accessory is proprietary and priced accordingly. Fan noise under heavy charge or load is louder than the marketing suggests, and at 164 lbs assembled you position it once and leave it. The 120A LRA rating starts most 3-ton air conditioners, which smaller stations simply cannot do. People cross-shop it against a Powerwall 3 install; the Ultra wins on no-permit portability, loses on per-kWh cost at scale.
Specifications
Highlights
Pros
- ✓7200W/240V single stack runs nearly any household load including central AC (120A LRA)
- ✓Scales from 6kWh to 90kWh - buy capacity only as you need it
- ✓Smart Home Panel 2 gives true automatic whole-panel backup
- ✓5.6kW solar input per inverter is generator-replacement territory
- ✓Owners report seamless outage transitions with SHP2 - lights barely flicker
- ✓No permits or utility interconnection needed unlike installed batteries
Cons
- ✗Ecosystem lock-in: SHP2, cables, and batteries are all pricey proprietary add-ons
- ✗Fan noise under load is prominent - not a bedroom device
- ✗164 lbs for inverter + one battery; genuinely two-person
- ✗Idle/standby consumption meaningfully drains stored energy over multi-day outages
- ✗At full build-out, cost per kWh exceeds an installed home battery

EcoFlow DELTA Pro 3
The single most-recommended whole-home-capable unit that still rolls on wheels. What sells it: 4000W with real 120/240V split-phase from one box, so it backfeeds a transfer switch and runs a well pump or mini-split without pairing two units. Owners consistently praise how quiet it stays at partial load (30dB claimed) and the 10ms UPS. The recurring complaint thread is idle drain - leaving AC output on burns tens of watts, so a 4kWh charge quietly evaporates over days if you use it as a dumb UPS without tweaking settings. It is 113 lbs; the wheels and handle work on pavement, not stairs. A few owners report warranty friction outside the mainland US, and early-firmware horror stories still circulate on Reddit, so update before first use. Street price has fallen from $3,699 to low-$2,000s, which changed the calculus versus F3800 Plus.

EcoFlow DELTA 3 Max Plus
The 2025-2026 refresh of EcoFlow's mid-size class and a current 'best for home backup' pick in several tested roundups. You get 2kWh and a 3000W inverter - enough to run a microwave and fridge simultaneously - at a price that undercuts the old Delta 2 Max's launch by hundreds. Owners like the practical stuff: 0-80% in about 68 minutes, X-Boost handling 3800W resistive loads, and expansion to 10kWh if backup needs grow. The dual side handles make the 49-lb carry manageable for one person. Quirks from owner threads mirror the rest of the Delta 3 line: fan spins up audibly during fast charging, idle drain means you shouldn't store it with AC output enabled, and the app occasionally loses Wi-Fi pairing until you power-cycle. Solid pick if 1kWh feels tight but 4kWh-class weight and price feel excessive.

EcoFlow DELTA 3 Plus
The default answer when someone asks r/portablepowerstations for a 1kWh backup unit. The killer feature owners rave about is the 10ms UPS switchover - people literally run NAS boxes, routers, and CPAP machines off it full-time and never notice an outage. It charges 0-100% in 56 minutes, which sounds like marketing until you watch it happen. Real-world quirks: the 30dB quiet claim only holds at idle - fast AC charging spins the fan up noticeably, so owners set a slower charge rate in the app at night. The app requires an EcoFlow account, which annoys the privacy crowd. X-Boost lets it fudge 2200W resistive loads (space heaters, kettles), but induction motors still trip it. Expansion to ~5kWh via extra batteries is handy, though the add-on packs cost almost as much as the unit on sale.
