The differences that matter
- 3.014 kWh vs 1.536 kWh → a 1000 W load lasts about three hours against an hour and a half.
- 1200 W vs 500 W solar input → with full sun a full recharge takes about two and a half hours against three.
- IP20 vs IP54 → the first should not be left where water can splash or dust can get in.
- 2 years vs 5 years of warranty → the EcoFlow can grow up to 5.5 kWh and stays covered longer.
Which one to choose
Choose BLUETTI Elite 300 if…
you want to start with more than 3 kWh in a single unit, where a 1000 W load lasts about three hours, with up to 2400 W continuous and 1200 W of panels. It has to stay indoors (IP20), has two mains outlets and a two-year warranty.
Choose EcoFlow DELTA 3 1500 if…
you plan to start with 1.5 kWh and grow to 5.5 kWh with add-on modules, or to use it in a room with dust or damp (IP54). You stop at 1800 W and 500 W of panels, and a 1000 W load lasts about an hour and a half; in return it has four mains outlets and a five-year warranty.
