Battery Input
Two groups of batteries are parallel with DC output of rectifier module
(keep the same polarity) via 63A circuit breaker, and work in FC (floating
charge) or EC (equalized charge) mode. The rated input voltage of the
battery is 48V with a rated volume of 50~500Ah.
Note:
1, By default, the battery group capacity is set to 100AH. If the actual
battery capacity is different, the setting should be changed accordingly
through the background lest the battery management should go wrong.
2These two groups of batteries actually conduct battery management
through a common power off contactor and a shunt. The battery current
tested by the monitoring module is actually the total current of two groups
of batteries. So the battery group number should be set as one group, and
the battery capacity should be set as the sum of two groups of batteries
the during the monitoring module background setting.
