- Not sold at any store we monitor today, so not in our ranking.
- No store we follow has this model in stock today.

## Our score

- Score 2.9 out of 10
- Owners’ ratings, 30%: none yet at the stores that ship to the United States, so this part is left out and the score is the features part alone.
- Features, 70%: 2.9, 26.195714285714285 of the 90 points for the maker’s facts, and the other 10 points counted at the market’s average share of 32%.
- Price does not count, so a discount never lifts a model. A home battery is ranked only when its kind is known and its maker states the usable capacity, the round-trip efficiency on the AC side, the standby draw and the warranty. A battery module is not ranked.
