
Set Battery capacity after repeated confirmation. An incorrect setting reduces the
charging power.

When a battery string is shared, the battery capacity of each UPS is the total capacity of
battery strings; when no battery string is shared, the battery capacity of each UPS is the
battery capacity of the single UPS.

A high or low charging power tends to shorten the battery lifespan, or even damages
batteries. To seek help about how to determine the battery capacity, contact Huawei
technical support.

Number of cells refers to the number of 2 V cells in a single battery string connected to
the UPS, and the number of cells must be a multiple of 12 (for example, 180 and 192). For
example, if 36 batteries (150 Ah, 12 V) are connected in series to form a battery string, and
two of such battery strings are connected in parallel and then to the UPS, set Number of
cells to 216 (36 x 6) and Battery capacity to 300 Ah (150 Ah + 150 Ah). If 192 batteries
(300 Ah, 2 V) are connected in series to form a battery string, and two of such battery
strings connected in parallel and then to the UPS, set Number of cells to 192 (192 x 1) and
Battery capacity to 600 Ah (300 Ah + 300 Ah). It affects the charge voltage and discharge
time. An incorrect setting will cause a high or low charge voltage, which greatly shortens
the battery lifespan. In addition, the UPS may shut down before the batteries are fully
discharged, which may lead to a data backup fault.
Step 3 If no exception alarm is reported on the monitoring page after you specify settings on the
Settings Wizard screen, perform subsequent steps. If exception alarms are reported on the
monitoring page, clear all the alarms.
Tap System Info > Settings > Dry contacts. Set the dry contacts that are used to Enabled and the dry
contacts that are not used to Disabled.
Step 4 Check that the bypass input is normal and the system has transferred to bypass mode. You can
confirm this by viewing the system running diagram on the LCD.
Step 5 Start the inverter.
