Recorded conflicts

environment temperature ranges Review required

charge 0 to 45 C; discharge -20 to 50 C; storage -20 to 50 C — EG4 manual 1.0.2 p.39-41

charge 0 to 50 C; discharge -20 to 55 C; storage 0 to 45 C — EG4 spec sheet VER 1.2.1

Document revision; all three ranges were restated between manual 1.0.2 and spec sheet VER 1.2.1.

physical dimensions Review required

880 x 566 x 232 mm (H x W x D) — EG4 manual 1.0.2 p.40, '34.6 in. x 22.3 in. x 9.1 in. (88.0 cm x 56.6 cm x 23.2 cm)'

916 x 566 x 232 mm — EG4 spec sheet VER 1.2.1, '36.1 x 22.3 x 9.1 in. (916 x 566 x 232 mm)'

Document revision - the height figure changed by 36 mm between manual 1.0.2 and spec sheet 1.2.1 (probably with/without the mounting bracket or the lifting lip).

nominal_voltage_v Review required

48 — existing ANMA record

51.2 — EG4 manual 1.0.2 p.39 and spec sheet VER 1.2.1, both 'Nominal Voltage 51.2V'

48 V is the nominal system class; EG4 prints 51.2 V (16S LFP) as the nominal pack voltage.

max_continuous_charge_current_a Review required

100 A default; 140 A / 200 A available via firmware update — EG4 manual 1.0.2 p.39-40 ('100/140/200A (Max. continuous)')

140 A max. continuous — EG4 spec sheet VER 1.2.1 (fetched 2026-09-02)

Document revision / firmware-dependent rating; the newer spec sheet publishes a single 140 A figure.

max_continuous_discharge_current_a Review required

200 A max. continuous — EG4 spec sheet 1.0.1 (the record's existing source_url) and manual 1.0.2 p.39

140 A max. continuous (200 A for 30 minutes maximum) — EG4 spec sheet VER 1.2.1 (fetched 2026-09-02) and the official product page 'max continuous discharge of 140A'

Document revision: EG4 restated the 200 A figure as a 30-minute rating and lowered the continuous rating to 140 A between spec-sheet revisions 1.0.1 and 1.2.1.
