Maximum number of bypass transfers within 30 minutes. The value ranges from 1
to 3. The default value is 3. When the number of bypass transfers exceeds the
maximum, the UPS keeps running is bypass mode (in ECO mode, the UPS keeps
running in normal mode). The parameter is configurable after the inverter shuts
down.
Do not set the UPS to ECO mode when the system output connects to an isolated transformer.

Output transformer
parameter
If an output transformer is connected, set the parameter to
Enabled
; otherwise, set
it to
Disabled
. The values include
Disabled
and
Enabled
. The default value is
Disabled
. The parameter is configurable after the inverter shuts down.
When you install a transformer on the output side, you are advised to connect the load to the pL terminal
and disable power segment.
−
Generator mode
parameter
The values include
Weak adaptability mode
,
Balance mode
, and
Strong
adaptability mode
. The default value is
Balance mode
. When the mains input
voltage quality is good, select
Weak adaptability mode
; when the quality is
average (for example, the mains input is from a high-performance generator or a
common power grid), select
Balance mode
; when the quality is poor (for example,
the mains input is from a common generator), select
Strong adaptability mode
.
The parameter is configurable after the inverter shuts down.
−
Auto check bus capa.
parameter
Determine whether to automatically check the bus capacitance upon power-on and
generate capacitance failure warnings. The values include
Disabled
and
Enabled
.
The default value is
Enabled
. If the value is
Enabled
, UPS startup takes additional
30–180 seconds. The parameter is configurable after the inverter shuts down.
−
Auto start
parameter
Determine whether to automatically start inverter output after the UPS connects to
the mains. The values include
Disabled
and
Enabled
. The default value is
