Item Description Default
Value
Value Range
Number of lead-acid
batteries supported
(The value of this
parameter must be
the same as the
setting of Batteries
in a battery string
on the UPS
monitoring screen.)
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 that the charge
and discharge operating voltage
ranges of the UPS and SmartLi
match each other.
By default, Number of lead-acid
batteries supported is set based on
the single battery voltage (2 V). If
the single battery voltage in the
UPS system is 12 V, convert it to 2 V
before setting this parameter. For
example, if the single battery
voltage is 12 V and the number of
batteries in a battery string is 42,
the value of Number of lead-acid
batteries supported is 252 (42 x
12/2 = 252) in the 7+7/7+0
scenario.

Battery cabinet
quantity
Species the number of battery
cabinets connected in parallel.
Currently, a maximum of 10 lithium
battery cabinets can be connected
in parallel.
1 1~10
Altitude (m) Set this parameter based on the
altitude of the place where the rack
is used.
≤ 1000 ≤ 1000, 1000–2000,
2000–3000, 3000–
4000
Step 7 If the green indicator of one BCU blinks at super short intervals and the red
indicator is steady on, switch on the battery circuit breaker on the battery cabinet
where the indicator blinks at super short intervals. In this case, the green
indicators of all BCUs blink intermittently, and you cannot switch on the battery
circuit breakers on other battery cabinets or start the UPS in cold mode.
Step 8 Wait for about 15s. After the green indicators of other BCUs blink at super short
intervals and the red indicator is steady on, switch on the battery circuit breaker
on each battery cabinet where the green indicator on the BCU blinks at super
short intervals.
