Install Setting
Correct passwords are requested when entering Install Setting. Install Setting for
user and installation technician are different. The password can not be revised.
After confirmation as the general user password, user can set Inverter ID,
Insulation, RCMU, Reconnection Time, Ramp-up Power and AC Conection.
CAUTION
！
Machine and equipment damage may occur.
The following settings can only be adjusted by installers or
engineers. Changing these settings may cause damage to the
inverter.
Insulation: Inverter will meansure the impedance between Array and PE
before connect to grid. If the impedance between Array and PE is lower then
the value that set in Insulation Settings, inverter will stop connecting to grid.
There are 6 modes users can select in Insulation settings: ON, Positive
Ground, Negative Ground, DC1 Only, DC2 Only, or Disable. Installer can
also select different impedance according to the actual situation.
DC Injection: Inverter will shutdown if the DC component in AC current over
the limit.
RCMU: If leakage current between input and output exceeds the limit,
inverter will shutdown immediately.
Reconnction Time: The countdown time before inverter connected to grid.
Ramp-up Power: The rate of increase in output power. (%/min)
AC connection: Users can choose 3P3W or 3P4W system depending on
the site conditions.
