The monitoring module can do battery test, and record 10 sets of test data
(accessible only through the host). The battery test has to be started
manually, then monitoring module will control the rectifier output voltage,
make it lower than the battery voltage, and the battery discharge will
begin. Monitoring module will stop the test if the battery voltage reaches
the ‘Battery test voltage’, or the discharge time reaches ‘Battery test time’,
or the battery capacity reaches ‘Test End Cap’. Afterwards, it will restore
the rectifier output voltage to the normal FC voltage, begin the battery
charge and switch the system to battery auto-management. Meanwhile
the test start time/voltage and end time/voltage and battery remaining
capacity will be recorded. The records can be queried through the host.
During the battery test, if abnormalities occur, the monitoring module will
stop the battery test automatically

When the parameter ‘Scheduled Test’ is set to ‘Y’, the monitoring module
will test the battery according to the 4 sets of test time. You can set at
most 12 sets of test time through the host

If the battery have not discharged within the ‘ShortTest Cycle’, the
monitoring module will start a short test, whose operation time is set by
the parameter ‘ShortTest Duration’. By the end of the test, if the difference
in the discharge currents of batteries is bigger than the ‘Alarm Current’,
the battery discharge imbalance alarm will be raised. This alarm will
automatically end after 5min of delay. Also you can end it by confirming it

The stable test is conducted with constant battery current, whose value is
set through the parameter ‘StableTest Current’. If the parameter
‘StableTest Enable’ is set to ‘Y’, and the test will be started once the
battery satisfies the test condition

The ‘Ambient Temp’ and ‘Battery Temp’ refer to the
measurement of the ambient or battery temperature sensor at
the local power system. ‘None’ means there is no measurement
input. You should set this parameter according to the actual
situation. The temperature measurement data will be displayed
in the system operation information screen
