RESU 10H Prime, the smallest listed size

Waiting past 31 Dec 2026 costs $440

Both RESU Prime sizes earn close to the full rate per kilowatt-hour, and the 16H gives up the full rate on just 2 kWh. Pick between them on the evening load you need to cover, not on the rebate.

How the RESU Prime sizes land on the taper

The RESU 10H Prime is listed at 9.87 kWh nominal and 9.6 usable, so all of it earns the full factor. The 16H Prime, at 16 kWh usable, crosses 14 kWh, and its last 2 kWh earn 60%.

Per kilowatt-hour that leaves the two within about 5% of each other: the 16H's taper loss is small.

Listing BAT-534 ends on 12 June 2027. LG's older RESU10 (8.8 kWh usable), RESU12 (11.7 kWh) and RESU6.5 (5.9 kWh) are still listed under separate certificates.

Other LG batteries on the list

LG has five entries on the list across three families, and the gap between label and usable differs between them: about 3% for the RESU Prime, about 10% for the older RESU models.

Before you sign for a RESU Prime

  • Check the quote says RESU 10H Prime or RESU 16H Prime. The older RESU10 is listed at 8.8 kWh usable, well below the 10H Prime's 9.6.
  • Both Prime models list nominal capacity slightly above usable (9.87 and 16.45 kWh); the certificates use 9.6 and 16.
