− Max. time parameter
Set the maximum discharge time. When the discharge time reaches the value, the
UPS powers off. The value ranges from 0Hour to 24Hour. The default value is
16Hour. If you set the value to 0Hour, the discharge time is not limited. The
parameter is configurable in non-battery mode or non-battery ECO mode.
 If you expect the battery discharge time to be greater than 24 hours, set Max. time to 0 hour.
Otherwise, the system may power off.
 If you set Max. time to 0 hour, the battery string may remain in the small-current discharge state
according to the proportion of the battery capacity to the load power, which affects the battery
lifecycle.
EOD mode parameter
−
Determine the power backup time. The values include Backup time first (ensures
system running and has a long backup time,
values), Batt. protect first (protects batteries and extends the battery lifespan,
Table 4-6 shows the EOD setting values), and Balanced mode
EOD setting values). The default value is Backup time first. The parameter is
configurable in non-battery mode or non-battery ECO mode. EOD is short for end
of discharge.
