How it compares

Where it sits among the 12 home batteries listed here (the best gets a full bar, the weakest a fifth, a figure the datasheet doesn't give none). Size isn't scored: the bars are shares and ratios. Cycle counts are measured at different depths and end points by each maker, so read them as a rough guide.

Usable share (depth of discharge) 95 %range 80–100

Cycle life 6000 cyclesrange 5500–6000

Power per kWh (continuous kW ÷ kWh) 1.0 ×range 0.5–1.0

Warranty 10 yearsrange 10–10

Warranty energy per kWh (MWh ÷ kWh) 4.59 range 2.15–4.59
