Alarm Name Alarm Description Action to Correct
Power Split Equalize
In Power Split mode, “System A” starts equalize
charging with the “System B”.
--
Power Split Battery Test
In Power Split mode, “System A” starts the test with the
“System B”.
--
Discharge Current Imbalance Battery distribution current imbalance alarm.
The currents from two groups of batteries are not
equal. Check the batteries.
Abnormal Battery Current
The equalize charging current exceeds the alarm
setting.
Check the alarm setting.
Temperature Compensation Active Battery charge temperature compensation is active. --
Battery Current Limit Active Battery is in current limit. --
Bad Battery Battery test fails. Check the batteries.
Battery Discharge Battery is discharging.
A battery test is active (the discharge test will stop
automatically). There is a mains failure (check that it is
not caused by open AC input circuit breaker). The
system load is higher than rectifier capacity, causing
the batteries to discharge (install additional rectifiers).
Battery Test Fail Battery test fails. Check the batteries.
Comp Temp High2
Compensation temperature sensor sensing
temperature higher than high temperature threshold 2.
Check why temperature is high or low. Comp Temp High1
Compensation temperature sensor sensing
temperature higher than high temperature threshold 1.
Comp Temp Low
Compensation temperature sensor sensing
temperature lower than low temperature threshold.
Compensation Sensor Fault Temperature Compensation temperature sensor failure. Replace temperature sensor.
System Temp1 High 2
Temperature sensor #1 sensing temperature higher
than high temperature threshold 2.
Check why temperature is high or low. System Temp1 High 1
Temperature sensor #1 sensing temperature higher
than high temperature threshold 1.
System Temp1 Low
Temperature sensor #1 sensing temperature lower than
low temperature threshold.
System Temp2 High 2
Temperature sensor #2 sensing temperature higher
than high temperature threshold 2.
Check why temperature is high or low. System Temp2 High 1
Temperature sensor #2 sensing temperature higher
than high temperature threshold 1.
System Temp2 Low
Temperature sensor #2 sensing temperature lower
than low temperature threshold.
System Temp3 High 2
Temperature sensor #3 sensing temperature higher
than high temperature threshold 2.
Check why temperature is high or low. System Temp3 High 1
Temperature sensor #3 sensing temperature higher
than high temperature threshold 1.
System Temp3 Low
Temperature sensor #3 sensing temperature lower
than low temperature threshold.
IB2-1 Temp1 High 2
Temperature sensor #1 (connected to IB2-1 board and
set as Battery) sensing temperature higher than high
temperature threshold 2.
Check why temperature is high or low. IB2-1 Temp1 High 1
Temperature sensor #1 (connected to IB2-1 board and
set as Battery) sensing temperature higher than high
temperature threshold 1.
IB2-1 Temp1 Low
Temperature sensor #1 (connected to IB2-1 board and
set as Battery) sensing temperature lower than low
temperature threshold.
