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
- 1.02 → 4.6 kWh: at the same load, the outage covered lasts about four and a half times longer.
- 1,800 → 3,800 W continuous: above 1,800 W the DELTA 3 is not enough; the SuperBase runs bigger loads together.
- 500 → 3,000 W solar input: the SuperBase can take a real array; with the DELTA 3, solar is a top-up.
- 5 → 3 years warranty: the DELTA 3 stays covered longer.
