Technical comparison · Home backup
Two LFP home batteries at different scales: 1.5 kWh that moves from room to room, and 4.6 kWh that stays where it is put. The choice depends on how long an outage has to be covered and how much you need to move the unit. Capacities and power figures are manufacturer-declared.

Most capable Flat-sized (3–8 kWh)
Highest technical score among the 6 sheets in the Home backup category (flat-sized tier): 84/100.
How we assign awards →The differences that matter
- 1.5 → 4.6 kWh: at the same load, the outage covered lasts about three times longer.
- 1,800 → 3,800 W continuous: above 1,800 W the DELTA 3 1500 is out of its range; the SuperBase runs bigger loads together.
- 500 → 3,000 W solar input: the SuperBase can take a real array; on the other unit, solar is a top-up.
- 5 → 3 years warranty: the DELTA 3 1500 stays covered longer.
Which one to choose
Choose EcoFlow DELTA 3 1500 if…
you need a battery you can carry around: 21 × 40 × 28 cm, IP54, four mains outlets. You can start at 1.5 kWh and expand later up to 5.5 kWh. You accept less reserve for the same outage and slower solar charging.
Choose Zendure SuperBase V 4600 if…
you want one unit for the whole home, with six mains outlets and 5,000 W of peak output for start-up surges. It charges from the grid at up to 4.608 kW and is declared for 6,000 cycles. The trade-off is 55 kg: it gets placed once and stays there, and its declared warranty is shorter.
