Recorded conflicts

nominal_energy_kwh (configuration mapping) Review required

H2 = 4030 Wh — official EN ECS4100 datasheet rev 3.22 energy row

H2 = 8060 Wh — DE ECS4100 datasheet 'Nennenergie' row; consistent with 2 modules x 4.03 kWh and with the H2 weight of 74.3 kg

column shift in the EN rev 3.22 energy row (the H2 value printed there equals the per-module 4.03 kWh); the per-module 4.03 kWh already stored in the record is unaffected

peak_current_a Review required

65 (existing record, distributor) — energian.co.uk product page

65 A @30sec — official EN ECS4100 datasheet rev 3.22

65 A (60 s) — Fox ESS ECS manual, 'Peak Discharge (60s) 65 A'

60 A @30sec — DE ECS4100 datasheet 'Spitzenstrom 60A @30sec'

document revision / differing pulse duration definition (30 s vs 60 s)

max_continuous_charge_current_a / max_continuous_discharge_current_a Review required

50 / 50 — Fox ESS ECS series manual, ECS4100 electrical table ('Max Charge/Discharge Current 50/50 A') - matches the value already stored

90 — official EN ECS4100 datasheet rev 3.22 row 'Max Charge/Discharge Current (A) 90'

25 — DE ECS4100 datasheet 'Max. Lade-/Entladestrom (A) 25'

the three documents appear to quote different scopes (per-module vs per-stack) and/or different document revisions; the 90 A figure may be a stack-level rating and the 25 A figure an older/derated revision. Safety-relevant - not resolved.
