Source: lg.com (verified 2026-08-01) · corroborated by saveonenergy.com. LG's official 'Home 5/8' spec sheet PDF (Resi_LGEUS_Home 8 Spec_0524) was downloaded and read directly: Home 8 total battery capacity 15.8 kWh with 14.4 kWh usable, rated AC power (discharging) 7.5 kVA continuous with 9.0 kVA max for 10 seconds, round-trip efficiency >90%, cylindrical Li-ion battery packs (chemistry given only as 'Cylindrical Li-ion' on the datasheet — many third-party reviews describe it as NMC but that specific term is not on LG's own sheet, so the datasheet's literal wording is used), 10-year warranty (70% capacity at 10 years), modular up to 4 units for 57.6 kWh, and a Smart Energy Box-rated backup transfer time of <100 ms (used as 100). Installed unit (PCS+Battery) weighs 163 kg / 359 lb. No consumer hardware price is published; SaveOnEnergy's independent review corroborates the 14.4 kWh capacity and cites $10,000-$12,000 installed. releaseDate left null — the spec sheet is dated 05/2024 but that is a document revision date, not a confirmed product launch year.
