Single/Parallel
Set the UPS running mode. The value can be
Single
(default) or
Parallel
.
Output voltage level (V)
Set the system output voltage level. The value can be 380 V, 400 V (default), or 415 V. If
Output voltage level
is 380 V or 400 V, the default upper limit of bypass voltage is 15%
and the default lower limit of bypass voltage is 20%. If
Output voltage level
is 415 V,
the default upper limit of bypass voltage is 10% and the default lower limit of bypass
voltage is 20%. The parameter is configurable after the inverter shuts down.
Output frequency (Hz)
Set the system output frequency level. The value can be 50 Hz (default) or 60 Hz.
Battery capacity (Ah)
Battery string capacity. The value range is 5–3000 Ah, 150 Ah by default.
Number of cells
Set the number of cells. Each 12 V battery consists of six cells. The value range is 180 –
276, 192 by default.
A cell consists of electrodes and electrolytes, which is the basic unit for the battery. Each cell has a
nominal voltage of 2 V. A battery is a unit consisting of single or multiple cells in a shell. Each
battery has a nominal voltage of 2 V or 12 V. The number of cells must be a multiple of 12 (for
example, 180 and 192).
