Overview
The DELTA Pro Ultra is EcoFlow's whole-home flagship and the largest entity in this index by both capacity and output. Unlike every other battery here it is a two-piece system: a separate inverter head unit (31.7 kg) stacks on one or more battery modules (50.7 kg each, 6,144 Wh). EcoFlow states 7,200 W continuous 'Pure sine' output at 120/240 V with a 10.8 kW surge, and publishes two distinct UPS behaviours — a Backup UPS at under 20 ms and an Online UPS at 0 ms — served by separate labelled outlet groups. Solar input is 5,600 W across a high-voltage 80-450 V port (4,000 W) and a low-voltage 30-150 V port (1,600 W), the widest PV envelope in this index by a wide margin. Expansion runs to 30 kWh on a single inverter and 90 kWh across a system.
Variant note: Base DELTA Pro Ultra (1 x inverter + 1 x battery). Distinct from the DELTA Pro Ultra X, from Starter Kit and Smart Home Panel 2 bundles, and from configurations adding further DPU Batteries or rigid solar panels. The DPU Battery is an expansion module, not a separate indexed entity. Also distinct from the original DELTA Pro and from DELTA Pro 3.
Data note: All values are taken verbatim from the official us.ecoflow.com DELTA Pro Ultra product page specification block on 2026-07-29. No user manual URL was located, so officialManualUrl is null and the record is held at medium confidence. TWO-PIECE PRODUCT: this is the only entity in this index sold as a separate inverter plus battery module. weightKg=82.4 is the sum of the two published net weights ('Inverter Net Weight: 31.7 kg (70 lb)' + 'Battery Net Weight: 50.7 kg (111.8 lb)') because neither component functions alone; this is a derived total and is flagged as such in provenance rather than presented as a published figure. dimensionsMm records the INVERTER only ('Inverter Dimension: 690 x 481 x 214 mm'); the battery module is separately stated as 660 x 455 x 204 mm and a working stack is taller than either figure. Do not read the dimensions as a whole-system footprint. acInputW=1800 follows the same convention as the DELTA Pro record — the US 120 V value — but the only 120 V figure EcoFlow publishes appears incidentally in a fault-code FAQ, so it is recorded at medium confidence; the clean 3,000 W maximum applies only to 240 V charging through the C20 inlet and is preserved in provenance. The 92-minute charge claim is a 6,200 W combined-input figure, not AC-only, so it is stored as a partial claim and acRechargeTimeHours is null. maxExpandableCapacityWh=90000 is the system ceiling; the single-inverter ceiling is separately stated as 30 kWh. rvPortPresent=false: no NEMA TT-30 appears in either outlet group. mpptPresent and carChargingSupported are null because no official statement was found.

Use cases
- Whole-home backup including 240 V circuits at up to 7,200 W continuous
- Sensitive-equipment and production loads needing 0 ms online-UPS switchover
- Very large solar arrays: 5,600 W input across an 80-450 V high-voltage port
- Multi-day off-grid operation scaling to 90 kWh
Strengths and weaknesses
Strengths
- 7,200 W continuous pure sine at 120/240 V — the highest output in this index
- 6,144 Wh per battery module, expandable to 30 kWh on one inverter and 90 kWh system-wide
- Publishes a true 0 ms Online UPS alongside a <20 ms Backup UPS, on separately labelled outlet groups
- 5,600 W solar input with an 80-450 V high-voltage string port — by far the widest PV envelope here
- IP54-rated battery and a -20 °C charging floor, unusual for this class
Weaknesses
- Two-piece system: ~82 kg across a 31.7 kg inverter and a 50.7 kg battery, and neither piece is useful alone
- US 120 V wall charging is modest relative to capacity; the 3,000 W figure requires a 240 V C20 inlet
- No NEMA TT-30 receptacle, so RV shore-power use needs an adapter
- No official 0-100% AC-only recharge time; the 92-minute figure is a 6,200 W combined-input claim
- Effectively an installed appliance rather than portable equipment

Sources and provenance
Every core field below carries the exact claim text it was normalized from, the official source, and the date it was checked. Policy: official manufacturer sources only for core specs; retailer and marketplace pages are never used as canonical sources. See the methodology for the full source hierarchy.
| Field | Normalized value | Raw claim | Source | Confidence |
|---|---|---|---|---|
batteryCapacityWh | 6144 | Capacity: 6144Wh, 102.4V⎓60A | Official spec page — Capacity of one battery module; the inverter head unit stores no energy. | high |
continuousAcOutputW | 7200 | AC Continuous Output: 7200W | Official spec page — Corroborated by the AC Output row: 'Discharging: Pure sine, 7200W total, 120V/240V~ 60Hz'. X-Fusion marketing language was not used as a separate boost figure. | high |
surgeAcOutputW | 10800 | AC Surge Output: 10.8kW | Official spec page — 10.8 kW normalized to 10,800 W. | high |
outputWaveform | pure_sine_wave | AC Output: Discharging: Pure sine, 7200W total, 120V/240V~ 60Hz | Official spec page — Explicit 'Pure sine' wording in the AC Output spec row — direct waveform evidence, not inferred from 'safe for electronics' language. | high |
numberOfAcOutlets | 6 | AC Output Socket (Backup UPS): 2 x 120V, 20A Max per port | 1 x 120V/240V, 30A Max / AC Output Socket (Online UPS): 2 x 120V, 20A Max per port | 1 x 120V, 30A Max | Official spec page — Two adjacent spec rows joined with ' / '; (2+1) + (2+1) = 6 across the Backup UPS and Online UPS groups. | high |
batteryChemistry | lifepo4 | Battery Chemistry: LFP | Official spec page | high |
acInputW | 1800 | There is a 274 fault code when using a 780W/5700W dryer and charging at 1800W/120V | Official support page — The US 120 V value is recorded per the convention used for the DELTA Pro record, but EcoFlow states it only incidentally inside a fault-code FAQ rather than in a spec row — hence medium confidence. The spec row itself gives amperage only ('Charging: 100-120V~15A; 200-240V~12.5A'), and no wattage was derived from volts x amps. Separately stated: 'When using the C20 outlet and charging at 240V, the maximum charging input is 3000W'. | medium |
solarInputW | 5600 | Solar Charging Input: Total 5600W, 2 ports | High-PV Input: 80-450V/15A, 4000W Max | Low-PV Input: 30-150V/15A, 1600W Max | Official spec page — 4,000 + 1,600 = 5,600, consistent with the stated total. This spec also appears in a comparison column on the DELTA Pro 3 page, where it describes this product rather than the DELTA Pro 3. | high |
weightKg | 82.4 | Inverter Net Weight: 31.7 kg (70 lb) / Battery Net Weight: 50.7 kg (111.8 lb) | Official spec page — DERIVED TOTAL, not a published figure: 31.7 + 50.7 = 82.4 kg for the minimum working configuration of one inverter plus one battery. Both component weights are quoted exactly. EcoFlow publishes no combined figure. | medium |
dimensionsMm | {"l":690,"w":481,"h":214} | Inverter Dimension: 690 x 481 x 214 mm (27.2 x 18.9 x 8.4 in.) | Official spec page — INVERTER ONLY. The battery module is separately stated as 'Battery Dimension: 660 × 455 × 204 mm (26 × 18 × 8 in.)'. A working stack is taller than either component, and no whole-system dimension is published. | medium |
cycleLifeRating | 3500 | Battery Cycle Life: 80% capacity after 3,500 cycles | Official spec page — Threshold explicitly stated, so cycleLifeThresholdPercent=80. | high |
upsEpsMode | ups | UPS: Backup UPS <20 ms; Online UPS 0 ms | Official spec page — Two distinct UPS behaviours are published and mapped to separately labelled outlet groups. Recorded as 'ups'; the 0 ms online mode is the stronger of the two and applies only to the Online UPS sockets. | high |
passThroughCharging | supported | Bypass: 100-120V~30A total, 50Hz/60Hz | Official spec page — A rated bypass mode in the AC Output row establishes pass-through operation. | high |
maxExpandableCapacityWh | 90000 | Expanable Capacity(System*): 90kWh (15 x DPU Battery) | Official spec page — Quoted exactly, including EcoFlow's 'Expanable' typo and asterisk. System ceiling across multiple inverters; the single-inverter row states 'Expanable Capacity (Single Unit): 30kWh (5 x DPU Battery)'. | medium |
rvPortPresent | false | AC Output Socket (Backup UPS): 2 x 120V, 20A Max per port | 1 x 120V/240V, 30A Max / AC Output Socket (Online UPS): 2 x 120V, 20A Max per port | 1 x 120V, 30A Max | Official spec page — Negative finding from the complete outlet list: no NEMA TT-30 receptacle is published, unlike the DELTA Pro and DELTA Pro 3. | high |
appControl | true | Connection: Bluetooth & Wi-Fi & 4G | Official spec page — 4G connectivity is unique to this model within the index. | high |
