Battery Over-Current

Charge or discharge current exceeds battery BMS limit.

Common causes

Inverter charge/discharge rate set too highMultiple loads causing high discharge currentBMS fault

What to check

STEP 1

Check inverter charge and discharge current limits. Dyness Powerbox G2: max 100A continuous. Fogstar Drift 16kWh: check Drift spec sheet for model

STEP 2

Reduce charge/discharge rate in Solis app if set above battery rating

Escalate if

Current within spec but fault persists — BMS fault, contact battery manufacturer
