Source: media.sonnengroup.com (verified 2026-08-01) · corroborated by sonnenusa.com. A sonnen 'Tech Specs' PDF (media.sonnengroup.com) was downloaded and read directly, titled 'sonnenCore' rather than explicitly 'sonnenCore+'; it lists a 10 kWh usable capacity option, 4.8 kW nominal (grid-tied) power rating, 5 kWh usable per battery module, LFP ('cobalt-free') chemistry, >85% round-trip efficiency (Grid<>Battery), a 10-year/10,000-cycle system warranty, and 348 lb weight; its off-grid specifications table gives a max 100ms surge rating of 36A/8.64 kVA (used here as peak_power_kw). Because sonnen's current sonnencoreplus product page (sonnenusa.com) independently confirms the same 10 kWh and 20 kWh capacity options, LFP chemistry, and identical 10-year/10,000-cycle warranty language, the two products are treated as sharing this hardware platform — but this should be read as a plausible inference, not an independently re-confirmed sonnenCore+-specific datasheet. Stackable up to 3 units / 60 kWh per the official product page. No confirmed backup-transfer-time-in-ms figure was found. releaseDate left null (sonnenCore+ succeeded the original sonnenCore around 2023-2024 but no single confirmed launch date was found).
