− Recovery delay time parameter
Delay time that the UPS takes in transferring from battery mode to normal mode
when the mains recovers. The value ranges from 0S to 900S. The default value is
5S. The parameter is configurable after the inverter shuts down.
If Recovery delay time is set to 0S, the actual recovery delay time is 1 second.
− Max. BPS transfers parameter
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.
− 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 must 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.
