Overview
The DELTA Pro 3 is EcoFlow's successor to the original DELTA Pro and the most capable dual-voltage battery in this index behind the Anker F3800. Its official spec block states 4,096 Wh of LFP rated 4,000 cycles to 80% capacity, and 4,000 W total continuous AC output at 120/240 V with an 8,000 W surge. X-Boost is published as a separate 6,000 W figure and is excluded from the continuous rating per this site's policy. The AC receptacle set is unusually complete: four NEMA 5-20R, a NEMA TT-30R for RV shore power, a 240 V NEMA 6-20R, and a 120/240 V NEMA L14-30R. EcoFlow states a 10 ms UPS switchover and confirms full 4,000 W output during pass-through charging. US grid charging is the notable limit — EcoFlow's own support text puts the US model's wall input at 2,000 W.
Variant note: Base standalone DELTA Pro 3. Distinct from the original DELTA Pro and DELTA Pro Ultra (separate indexed or separate products), and from bundles pairing the unit with DP3 Extra Batteries, solar panels, Smart Home Panel 2, or the Smart Generator. The DP3 Extra Battery is an accessory, not a separate indexed entity.
Data note: All values are taken verbatim from the official us.ecoflow.com DELTA Pro 3 product page specification block on 2026-07-29. No user manual URL was located for this model, so officialManualUrl is null and the record is held at medium confidence. SOLAR INPUT — EARLIER APPARENT CONFLICT RESOLVED: this record's solar figure comes from the product's own spec block, 'Solar Charging Input: 2600W total, 2 ports | High-PV Input: 30V-150V, 15A, 1600W Max | Low-PV Input: 11V-60V, 20A, 1000W Max' (1600 + 1000 = 2600). A comparison table on the same page also shows 'Total 5600W ... High-PV Input: 80-450V/15A, 4000W Max', which was initially recorded here as a possible conflict; it has since been confirmed to be the DELTA Pro Ultra's specification appearing in a comparison column, not an alternative figure for the DELTA Pro 3. There is no conflict, and 2,600 W stands. acInputW=2000 comes from EcoFlow's own support text for the US model rather than a spec-table wattage, because the spec row states only amperage ('Charge Only: 100-240V~15A 50/60Hz'); per policy a wattage was not derived from volts x amps. X-Boost 6,000 W is excluded from continuousAcOutputW per policy. numberOfAcOutlets=7 counts 4 x 5-20R + 1 x TT-30R + 1 x 6-20R + 1 x L14-30R. maxExpandableCapacityWh=48000 is the system maximum, stated as 'Up to 48kWh**' with an asterisk; the single-unit ceiling is separately stated as 12 kWh. Dimensions are recorded in the order EcoFlow prints them (410.4 x 341 x 693 mm), which places the largest figure in the height position. The 12V DC output row prints '2.6V 30A, 378W total', where 2.6 V is very likely a typo on EcoFlow's page; no 12 V figure was recorded from it and no car socket was claimed. mpptPresent and outputWaveform are null/unspecified because no official statement was found, not because the features are absent.

Use cases
- Whole-home and 240 V circuit backup at up to 4,000 W continuous
- RV shore power directly via the built-in NEMA TT-30R receptacle
- Split-phase 240 V loads through the NEMA L14-30R outlet
- Job-site tool use with 8,000 W surge headroom and 10 ms UPS switchover
Strengths and weaknesses
Strengths
- 4,000 W continuous at 120/240 V with an 8,000 W surge
- The most complete AC receptacle set in this index: 5-20R, TT-30R, 6-20R and L14-30R
- 4,000 cycles to 80% — the highest published cycle rating of any battery here
- 10 ms UPS switchover, and full 4,000 W output confirmed during pass-through charging
- Built-in TT-30 RV outlet, so a 30 A shore-power cable plugs straight in
Weaknesses
- 51.5 kg — a wheeled unit, not carryable
- US wall charging is limited to 2,000 W by EcoFlow's own support text, modest for a 4,096 Wh pack
- No official 0-100% AC recharge time is published; only an 80%-in-50-minutes partial claim
- 2,600 W solar input is modest next to the DELTA Pro Ultra's 5,600 W, and the low-PV port is capped at 1,000 W
- The 48 kWh expansion ceiling is a multi-unit system maximum, not a single-unit capacity (single unit tops out at 12 kWh)

acInputW | 2000 | Typyically, the grid charging port on the US model only supports AC 120V 2000W charging (Level 1) | Official support page — Quoted exactly, including EcoFlow's 'Typyically' typo. Used because the spec table states only amperage; no wattage was derived from volts x amps. Medium confidence as it is support/FAQ prose rather than a spec row. | medium |

A 5,600 W figure visible in a comparison column on the same page belongs to the DELTA Pro Ultra, verified against that product's own spec block on 2026-07-29 — it is not a competing figure for this model. | high |
