Same brand, same 7,200W. The TITAN is built to save on the bill; the DELTA Pro Ultra to ride out the outage.
The EcoFlow TITAN 5000 Plus is a fixed indoor home battery: 5,017.6Wh in one 121.3 lb box, 8,000W of solar, IP20, no wheels, a 10-circuit Smart Home Panel 10 that can couple existing rooftop solar, and up to 30kWh. The EcoFlow DELTA Pro Ultra is an inverter plus a 6,144Wh battery, 70 lb and 111.8 lb on a rolling cart: 5,600W of solar, IP54, charging down to −4°F, a TT-30 and a 12V output, and up to 90kWh with three inverters. EcoFlow itself pitches the TITAN for everyday savings and the Pro Ultra for homes with frequent outages.
Below: every difference with numbers, a 20-second calculator for your own gear, seven modeled situations, and what published reviews found. As of November 1, 2026, no independent review of the TITAN had been published, so every TITAN figure on this page comes from EcoFlow’s US product page.
Same 7,200W at 120V and 240V. The DELTA Pro Ultra stores 1,126Wh more per battery, is IP54, charges down to −4°F, has a TT-30 and 12V and scales to 90kWh. The TITAN 5000 Plus takes 8,000W of solar in one lighter box and couples existing rooftop solar.
- you’ll run more than 5,600W of solar
- you want rooftop solar coupled in
- you want one box indoors
- it lives in a cold garage
- you want more battery per unit
- you need a TT-30 or 12V
The five differences that decide it
Both deliver 7,200W at 120V and 240V, use LFP cells, pair with an EcoFlow home panel, use the EcoFlow app and carry a 5-year warranty. These five gaps decide it.

Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. About 4,265Wh usable on the TITAN 5000 Plus and 5,222Wh on the DELTA Pro Ultra with one battery.
Appliance for appliance, the Pro Ultra lasts 22% longer than the TITAN 5000 Plus.

What each one costs today
The EcoFlow DELTA Pro Ultra (1 battery) costs $500 more than the EcoFlow TITAN 5000 Plus and adds 1,126Wh: that is $0.44 per extra Wh, against $0.74 per Wh for the TITAN 5000 Plus.
Prices refresh daily from EcoFlow US.What the $500 buys: 1,126Wh more battery (6,144Wh vs 5,017.6Wh), charging and running down to −4°F, and an IP54 rating.
The DELTA Pro Ultra holds 1,126Wh more per battery, so compare price per Wh as well as the sticker price. We skip cost per cycle: EcoFlow publishes no cycle rating for the TITAN. For whole-home backup, add the panel and an electrician to either: the Smart Home Panel 10 for the TITAN, the Smart Home Panel 2 for the DELTA Pro Ultra.
Seven modeled situations, worked out
Same formula as the calculator above, with one battery each. The DELTA Pro Ultra carries 1,126Wh more, so it runs about 22% longer on every load; the TITAN answers with solar.
24-hour outage, essentials only
Two days on either, about 10 hours more on the DELTA Pro Ultra. Digital Trends kept a house warm with a 3,100W heat pump on the Pro Ultra and its panel.
Refill from solar, each at its maximum
The TITAN refills in under an hour of strong sun at full input, and with its panel and a CT sensor it can also store surplus from existing rooftop solar.
A garage at 20°F in January
The DELTA Pro Ultra charges and discharges down to −4°F and is IP54. The TITAN won’t charge below 32°F, runs down to 14°F, and EcoFlow places it in a dry, ventilated indoor spot.
A 3-ton central AC
EcoFlow says the TITAN starts a compatible 3-ton AC without a soft starter, with no surge figure published; the DELTA Pro Ultra lists 10,800W of surge. The TITAN can also put up to 5kW on one 120V leg.
An RV or 12V gear
Only the DELTA Pro Ultra has a TT-30 and a 30A 12V output. The TITAN’s outlets are two 5-20R and an L14-50R twist-lock.
Home office through an outage
More than two workdays on both. The DELTA Pro Ultra’s online UPS gives 0ms on three outlets; EcoFlow says the TITAN’s EPS switches within 10ms with gear plugged in directly.
Growing the system later
Both take five extra batteries per unit, about 30kWh. The DELTA Pro Ultra goes further: 90kWh and 21.6kW with three inverters, per EcoFlow.

Practical consequence: the DELTA Pro Ultra has the outlets of a station, four 20A outlets, a TT-30, an L14-30, a 6-20R, USB and 12V. The TITAN 5000 Plus has two 20A outlets and an L14-50R twist-lock, and feeds the rest of the house through its panel.
08 · NoiseNoise: TITAN 5000 Plus vs Pro Ultra
EcoFlow rates both as quiet, at different loads: the EcoFlow TITAN 5000 Plus under 39dB at 5,000W, at 1 m, and the EcoFlow DELTA Pro Ultra (1 battery) fanless, at 0dB, under 2,000W for up to 30 minutes. Yahoo Tech never heard the Pro Ultra’s fan during whole-home outage tests.
Brand figures. No independent dB measurement exists for either.Every figure we found, with its source
What reviewers heard: Never heard a fan during whole-home outage tests (Yahoo Tech); silent running under a 2,000W load (Trusted Reviews, UK unit); very quiet after a month (SlashGear).
Measured by a tester Brand figure
- Both usually live in a garage or utility room; the noise ratings matter most if yours sits next to a bedroom wall.
Cold and heat: TITAN 5000 Plus vs Pro Ultra
The EcoFlow DELTA Pro Ultra (1 battery) is rated for garages and covered outdoor spots: IP54, charging and running down to −4°F. The EcoFlow TITAN 5000 Plus stops charging at freezing, runs down to 14°F and is IP20, for a dry, ventilated indoor spot.
Figures from the EcoFlow US TITAN 5000 Plus and DELTA Pro Ultra pages.- Put the TITAN in a dry, ventilated indoor spot and charge it above 32°F.
- For a garage or covered outdoor spot, the DELTA Pro Ultra is the one: IP54, and it charges down to −4°F.
App, UPS and smart features
Same app, different strengths. The EcoFlow TITAN 5000 Plus couples existing rooftop solar and has a storm mode; the EcoFlow DELTA Pro Ultra (1 battery) adds 4G, generator auto start and a 0ms online UPS on three outlets.
Both pair with an EcoFlow home panel and schedule charging by rates.Does it work with existing rooftop solar? With the Smart Home Panel 10 and a CT sensor, the EcoFlow TITAN 5000 Plus stores surplus from an existing grid-tied solar system. We found no such feature listed for the EcoFlow DELTA Pro Ultra.
Can it start a generator by itself? The EcoFlow DELTA Pro Ultra can start and stop a generator on its own; EcoFlow lists generator charging for the EcoFlow TITAN 5000 Plus through its AC cable, but no auto start.
Does it work as a UPS? EcoFlow says the EcoFlow TITAN 5000 Plus’s EPS switches within 10ms with appliances plugged in directly, and within 20ms through the Smart Home Panel 10; its spec table leaves the field blank. The EcoFlow DELTA Pro Ultra switches in under 20ms, and its online UPS covers three outlets at 0ms.
Does it connect to a home panel? The EcoFlow TITAN 5000 Plus pairs with the Smart Home Panel 10, 10 circuits; EcoFlow lists 12 smart circuits for the EcoFlow DELTA Pro Ultra with the Smart Home Panel 2. SlashGear found the Pro Ultra took about four seconds to take over house circuits through the panel unless EPS mode was on.
Can it charge off-peak? Both follow time-of-use rates in the EcoFlow app; EcoFlow lists habit learning and 3-day solar forecasting on the EcoFlow TITAN 5000 Plus as a subscription feature.
Can you add a battery later? The EcoFlow TITAN 5000 Plus takes up to five TITAN 5kWh Battery, 30kWh; the EcoFlow DELTA Pro Ultra up to five 6,144Wh batteries per inverter, 30.7kWh, and 90kWh with three inverters.
How does the app connect? Both use the EcoFlow app; the EcoFlow DELTA Pro Ultra adds 4G.
Warranty and support
Both carry 5 years with no registration condition stated. EcoFlow covers the EcoFlow TITAN 5000 Plus main unit, its extra batteries and the Smart Home Panel 10 for 5 years each, and the EcoFlow DELTA Pro Ultra (1 battery)‘s inverter and battery for 5 years each.
Same brand, same term.Subject to each brand’s warranty terms and eligibility.
EcoFlow rates the DELTA Pro Ultra at 3,500 cycles to 80%. EcoFlow US doesn’t publish a cycle rating for the TITAN 5000 Plus.

What reviewers report
We have not lab-tested these two units. As of November 1, 2026, no independent review of the TITAN had been published, so every TITAN figure on this page comes from EcoFlow’s US product page. The DELTA Pro Ultra side draws on five published tests. Each point gives the source, author and date; UK and EU units are flagged, since their charge times and outlets differ from US units.
