Sigenergy SigenStor: 2024 vs 2026 generation — what changed

Sigenergy's CEC register listings span two distinct hardware generations under the same "Sigen Energy Storage System" series. Both remain CEC-active and individually resolvable — this page lists what actually changed between them, sourced from CEC approval dates and per-module capacity fingerprints, not marketing copy.

2024 generation

CEC approval window: Jan 2024 – Dec 2025
Per-module usable capacity: 5.38 kWh, 8.06 kWh

2026 generation

Current

CEC approval window: Jan 2026 – ongoing
Per-module usable capacity: 6.02 kWh, 9.04 kWh, 11.4 kWh

What this means for a listing

Every configuration from both generations stays browsable and individually resolvable to its own spec page — nothing is hidden, only sorted.
Current-generation configurations are listed first on the series page and in catalogue browsing; earlier-generation configurations carry an "Earlier generation" label rather than being removed.
The two generations don't share an exact nominal-capacity configuration, so there's no clean one-to-one "this exact size was replaced by that exact size" mapping — compare the full configuration list on the series page instead.
