4.2.4.5 Bypass Settings

Issue 02 (2022-12-30)
Description
This parameter can be
adjusted based on site
requirements. If the output
frequency track rate is slow,
the inverter frequency is
different from the bypass
frequency when the bypass
frequency changes. If the
output is overloaded or the
inverter is faulty, an
interruption (less than 20
ms) occurs when the UPS
transfers from normal mode
to bypass mode. If the output
frequency track rate is fast,
the inverter frequency may
be unstable.
The UPS transfers to battery
mode when the mains is
abnormal. When batteries
reach the end of discharge
(EOD) threshold and the
bypass is unavailable, the
UPS powers off. After the
mains recovers, the UPS will
automatically restart if EOD
restart is set to Enable.
If this parameter is set to
Disable, you need to
manually rectify the fault
and then start the UPS, or
you can set this parameter to
Enable.
If EOD restart is set to
Enable, the UPS starts
working after the time set for
EOD restart delay when the
input recovers from a power
failure upon battery EOD.
