BLUETTI Elite 300 vs EcoFlow DELTA 3
Technical comparison · Home backup
BLUETTI Elite 300 and EcoFlow DELTA 3 set the trade-off in opposite directions within the same home backup category: more power and capacity right away on one side, more years of coverage and room to grow on the other. The difference that matters most is warranty, reversed compared to power and capacity.

The differences that matter
- Maximum solar input: 1200 W vs 500 W → the Elite 300 recharges faster from solar panels.
- Warranty: 2 years vs 5 years → the DELTA 3 carries a longer manufacturer coverage.
- Continuous output: 2400 W vs 1800 W → the Elite 300 runs more appliances together.
- Peak output: 4800 W vs 3600 W → the Elite 300 absorbs higher startup load spikes.
Which one to choose
Choose BLUETTI Elite 300 if…
Choose BLUETTI Elite 300 if you need more capacity right away (3 kWh vs 1 kWh) and don't plan to expand it later. The trade-off is shorter warranty coverage.
Choose EcoFlow DELTA 3 if…
Choose EcoFlow DELTA 3 if you'd rather have a lighter unit (12.5 kg vs 26.3 kg) and want to expand it later up to 5 kWh with a module, with longer warranty. The trade-off is less power available until you expand.
