RW Spring Series Battery

BatteryFault

Also applies to:RW-L2.5ARW-L5.1RW-L10.2RW-F16SE-F5SE-F5 PlusSE-F5 ProSE-F12+7

What it means

Discharge over current — Discharge current exceeded the battery's over-current protection limit and discharging was interrupted.

Cause: Load or inverter demand exceeded the battery's rated discharge current, or a surge (e.g. motor/compressor start) tripped the protection.

How to fix it

Reduce the connected load or the inverter's discharge-current limit.
After the BMS recovers, confirm the steady load is within the battery's rating.

GB-A HV Battery

BatteryFault

Also applies to:GB-A

What it means

ALARM_ID_DSG_LOW_TEMP_LEV_2 — The discharge temperature is too low.

Cause: Cell temperature is below the minimum discharging temperature - the battery environment is colder than the rated discharge window.

How to fix it

Warm the installation space and wait for the cells to return to the operating temperature range.
