EcoFlow DELTA 3 Plus: 1,024 Wh, 1,000 W Solar
EcoFlow DELTA 3 Plus: 1,024 Wh LiFePO4, 1,800 W continuous, 3,600 W surge, two 500 W solar inputs. How it differs from the DELTA 3.
Which version: Not the DELTA 3 (same 1024 Wh and 1800 W, 100W USB-C, one 500W solar input) or the DELTA 3 Classic (not expandable); also not the DELTA 3 Max Plus (2048 Wh, 3000 W).

The DELTA 3 Plus is the version of EcoFlow's 1,024 Wh DELTA 3 with faster USB ports and a second solar input. It shares its battery and its 1,800 W / 3,600 W output with the DELTA 3, but adds two 140 W USB-C ports (100 W on the DELTA 3), 36 W USB-A and two 500 W solar inputs for 1,000 W in total (one 500 W input on the DELTA 3). The DELTA 3 Classic drops expansion and the car outlet. The DELTA 3 Max Plus is a different, 2,048 Wh unit.
The numbers that decide backup use
Six outlets share 1,800 W continuous with 3,600 W surge. That starts the top-freezer refrigerator (1,200 W), the 1/2 HP sump pump (2,150 W) and the gas furnace blower (257 W running, 1,600 W start). X-Boost is a boost mode, not a continuous rating.
Using the 0.85 factor explained on the methodology page, 1,024 Wh × 0.85 ÷ 47 W gives about 18.5 hours for the top-freezer refrigerator at its yearly-average draw, or 3.4 hours for the furnace blower at 257 W.
EcoFlow rates the battery for 4,000 cycles to 80+ % capacity. Jackery's 4,000 cycles are counted to 70 %, so read the threshold, not just the count (how makers define cycle life).
Charging, UPS and gaps
At 1,500 W AC input EcoFlow quotes 0–100 % in 56 minutes; UPS switch-over is under 10 ms. Expansion reaches 5 kWh through DELTA 3, DELTA 2, DELTA 2 Max or DELTA Pro 3 extra batteries. No operating temperature range is printed. The unit weighs 27.6 lb.

Frequently asked questions
Is the DELTA 3 Plus worth it over the DELTA 3 for backup?
The battery and AC output are the same (1,024 Wh, 1,800 W). The Plus adds faster USB-C (140 W per port) and a second 500 W solar input. If you recharge from solar during an outage, the second input is the practical difference.
Can it run a furnace blower?
On the published numbers, yes: the gas furnace blower in our database needs 257 W running and 1,600 W to start. At 257 W, 1,024 Wh × 0.85 ÷ 257 W gives about 3.4 hours of blower run time.
Does it work as a UPS?
EcoFlow lists a UPS switch-over under 10 ms.
How loud is it?
EcoFlow gives under 30 dB at 600 W and under 40 dB at 1,200 W.
