A warning state is triggered when a condition, such as voltage or temperature,
is beyond its design limitations.
The battery pack’s BMS periodically reports its operational state to the inverter.
There are two abnormal states:
Warning
: When the battery pack is likely to become faulty, it goes into warn-
ing state. When a warning is reported, the inverter shows the warning
message on its display but takes no action about it.
Fault
: When the battery pack falls outside prescribed limits, it goes into fault
state. When a fault is reported, the inverter immediately stops its opera-
tion and shows the fault message on the display.
The possible warning or fault messages are as follows:
• Battery Over Voltage
• Battery Under Voltage
• Battery Over Temperature
• Battery Under Temperature
• Battery Discharge Over Current
• Battery Charge Over Current
