Everything below comes from what LG Energy Solution publishes about the JF2 AC LINK (2HR / 4HR): the datasheet, the product page and press releases. Where a figure is not published, the field says so — we do not estimate.
Variants
Energy figures are nominal (beginning of life) as published by the manufacturer. One model, several duration options — the same enclosure with different power ratings.
| Variants | Energy | Power | Duration |
|---|---|---|---|
| JF2 2HR AC LINK — 5.11 MWh / 2.55 MW, 690 Vrms, 0.5 CP | 5.11 MWh | 2.55 MW | 2 h |
| JF2 4HR AC LINK — 5.11 MWh / 1.32 MW (6 × 220 kVA), 690 Vrms, 0.25 CP | 5.11 MWh | 1.32 MW | 4 h |
