NOTE
● The number of batteries is 0 by default and needs to be set based on site
requirements. Batteries have no neutral wire, and an odd number of batteries
are supported.
● When the UPS works in normal mode, if the actual load rate exceeds the
threshold that could trigger battery derating, an output overload alarm is
generated.
1108 A (480 V, forty 12 V batteries in standard configuration)
1327 A. It is the EOD current of forty 12 V batteries in standard
configuration, that is, two hundred and forty 2 V battery cells (1.67 V/
cell).
If a utility power outage occurs, batteries can start the UPS to supply
power to loads.
The maximum charge power is 15% of power of a single module, and
the charge current is limited to 30 A.
● Lead-acid battery: Battery string sharing is supported in a parallel
system. No battery is shared by default.
● SmartLi 2.0: Battery string sharing is supported in a parallel system.
No battery is shared by default.
● SmartLi 3.0: Battery string sharing is not supported.
