Introduction
2.1
Features
The EM048063P3S and EM048126P3S series battery modules have the following fea-
tures:
Built-in battery management system (BMS)
: A battery module’s BMS monitors its
operation and prevents the battery from operating outside design limitations.
When a battery module enters an abnormal state, the BMS issues an alert and
restricts or disables the battery’s operation.
Hot-swap capability
: Faulty battery modules can be replaced while the ESS remains
in operation.
NOTE
This feature is not supported with the residential models.
Scalability
: An ESS can comprise up to 10 units connected in parallel. Battery mod-
ules can be arranged not only layer upon layer but also side by side.
Power saving
: When a battery voltage drops below the specified limit, it turns off.
The battery module wakes up when a voltage higher than or equal to 33 V is
applied.
