EcoFlow DELTA 3 Max Plus
The DELTA 3 Max Plus combines a 2,048 Wh battery with 3,000 W AC output and up to 1,000 W solar input. It is the more capable Max model, at the cost of a heavier 22.1 kg lift.
Pre-order listedOur take
Choose the Plus for higher running loads or a larger solar setup, if its 22.1 kg weight suits you. Check the current price and delivery options.
EcoFlow UK listed the standalone Plus at £1,099 and the Max at £1,199 on 2 October 2026. Those are dated observations. Sold-out and preorder notices made ordering availability unclear; check that you can order the exact model and when it will arrive.
The Plus still has the same 2,048 Wh battery. Its higher output lets it supply a larger combined load; it does not give that load longer runtime. Choose it for the equipment or charging setup you need, rather than expecting extra energy from the Plus name.
