Wie wir das erstellt haben
13 notable home battery backup systems selected as the 2026 buyer comparison set. All 12 seeds from the brief were verified; one was corrected: EcoFlow 'PowerOcean' is an EU/UK-market product line (homebattery.ecoflow.com/eu) that is not sold in the US — the current US-market EcoFlow home-battery product is 'OCEAN Pro' (energy.ecoflow.com/us), so the entry was replaced with EcoFlow OCEAN Pro and the correction is noted in its provenance. HomeGrid Stack'd Series (a Signature Solar / Lithion house brand) was added as a 13th product representing the modular, budget-oriented segment of the market. This category is dominated by installer-sold, quote-priced hardware: SolarEdge, Generac, Panasonic, LG, FranklinWH, Enphase and HomeGrid publish no consumer MSRP (sold exclusively through certified dealer/installer networks; wholesale distributor pages are frequently login-gated), so priceUsd is null for those with only third-party installed-cost estimates recorded in priceNote per the null-over-guess rule. Only Tesla (hardware price consistently and independently cited by multiple solar-industry reviewers since Tesla's own site is quote/app-only), Savant (MSRP stated in its 2023 trade-press launch coverage) and sonnen (a real distributor sale-price listing) carry a priceUsd. Specs were pulled from manufacturer datasheets/spec sheets wherever fetchable (Tesla, Enphase, FranklinWH, LG, Generac, Bluetti, Savant, sonnen, Anker, EcoFlow, HomeGrid official pages/PDFs) with manufacturer or reputable secondary sources (EnergySage, SolarReviews, trade press) as corroboration; several primary datasheet PDFs (Tesla, SolarEdge) returned HTTP 403 to automated fetch and were corroborated instead via secondary sources that quote the same official figures. 'usable_capacity_kwh', 'continuous_power_kw' and 'priceUsd' all describe the smallest/entry hardware configuration a US buyer can purchase for each modular system, not its maximum expandable size (max expansion is noted in each product's provenance). 'continuous_power_kw' is the sustained AC output rating (off-grid/backup mode where the two differ); 'peak_power_kw' is the manufacturer's short-duration surge rating (typically 3-10s) at that same base configuration, derived from published max-start-current figures where a manufacturer did not label a figure 'peak' outright (shown in provenance). round_trip_efficiency is a plain percentage number. accessedAt 2026-08-01 on all entries.
