In the float charging status, all rectifiers output voltage
according to the setting value of ‘Float charging voltage’
The setting value of ‘Boost
charging voltage’ must be
higher than that of ‘Float
charging voltage’

The monitoring module detects the charging current of the battery. If the charging
current is higher than the setting value of the ‘current limit point’, the monitoring
module will send current limit control command to limit the charging current of the
battery.

The monitoring detects the charging current of the battery. If the charging current is
higher than the setting value of the ‘over current point’, the monitoring module will
generate alarm o battery charging over current

enabled
If selecting ‘Enabled’, after the time in which the power system has been in the float
charging status reaches that set in the ‘Timing boost charging period’, the monitoring
module will control the power system to conduct timing boost charging. The battery
charging voltage is setting value of ‘charging voltage’ and the charging time is setting
value of ‘Timing boost charging duration’

When the battery capacity reduces to the setting value of ‘Boost charging conversion
capacity’, or when the charging current reaches the setting value of ‘Boost charging
conversion current’, the monitoring module switches the system to the boost charging.
The battery charging voltage is the setting value of ‘Boost charging voltage’

When the system is in the boost charging status, if the charging current is as low as
the setting value of ‘Constant boost charging current’, the system will automatically
transfer to the boost charging after the time set in the ‘Constant boost charging time’.
The battery charging voltage is the setting value of ‘Float charging voltage’
