The differences that matter
Manufacturer-declared values. - Capacity and weight, 1 vs 2 kWh and 11.5 vs 20.3 kg → half the energy, but 8.8 kg less to carry. - Noise, 50 vs 25 dB → the gap decides where the unit can stay switched on. - Mains charging, 1.2 vs 2.3 kW → both take about an hour to fill, but the second fills a battery twice the size. - Warranty and expansion, 5 years vs 3, expandable only on the first → the first can grow and is covered two years longer.
Which one to choose
Choose BLUETTI Elite 100 V2 if…
you move the unit often and want to start small, adding batteries when needed. From panels, at 1000 W of input, the kilowatt-hour refills in about an hour of full sun, and the warranty runs five years. The unit runs at a declared 50 dB, though.
Choose EcoFlow DELTA 3 Max if…
the unit sits in a lived-in room and you want 2 kWh on board, with loads up to 2400 W. It cannot be expanded, from panels at 500 W a full refill takes about four hours of full sun, and it weighs more.
