Description
Specifies the SmartLi connection scenario.
Application scenario
Currently, the UPS and EHU scenarios are
supported.
When the SmartLi is connected to the UPS
without communication, the UPS manages
the SmartLi based on the lead-acid battery
logic. You need to set the number of lead-
acid batteries supported for the UPS on
the SmartLi monitoring screen to ensure

battery voltage is 12 V and the number of
batteries in a battery string is 42, the value

steady on, switch on the battery circuit breaker on the battery cabinet.
The preceding procedure applies to the single-cabinet scenario. For the multi-cabinet

•
If battery modules will be stored for a long time after power-off, remove the BCU to
reduce battery discharge. This prevents battery modules from being overdischarged due
to storage at low SOC.

If battery modules are stored without being fully charged, charge them according to the
