1.5.6 Charger Module
Figure 11 shows the charger module.
Figure 11 Appearance of the charger module
In AC mains mode, the charger module charges the system battery modules or external battery
cabinet. Each charger module is rated to deliver 10A charging current. The charger module has an
independent control function and maintains real-time communication with the system and the
battery modules to ensure stable charging and fault protection.
The charger module may be added or replaced on-line with no interruption or danger to the user,
connected battery system or connected equipment.
1.5.7 External Battery Cabinet (EBC)
The external battery cabinet is divided into nine rows: the upper seven rows are for use with the
intelligent battery modules, and the lower two are used for overcurrent protection for each battery
cabinet. For normal operation, two battery modules must be inserted in the same row of the frame to
create a complete string. The battery module strings work in parallel to provide longer backup time
for the UPS. A SolaHD S5KC can be configured with, at most, four external battery cabinets.
An external battery cabinet is shown in Figure 12.
