Coefficient Setting

Users can set the following parameters according their needs.
7.2.6.3

Installation Settings

A password is required to enter the Installation Setting. These settings are
different for end customers and installers. The password once set, cannot be
reset. Once a the correct password has been entered, access to configure the
Inverter ID, Insulation, RCMU, Reconnection Time, Ramp-up Power and AC
Connection will be granted.
CAUTION !
The following settings can only be adjusted by installers or
engineers. Changing these settings may result in damage to the
inverter and other equipment.
 Insulation: Inverter will measure the impedance between the Array and PE
before connecting to grid. If the impedance is lower than the value that is 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, and Disable. After an analysis has
been made for the site, the impedance should be set to best suit the
environment of the installation.
 DC Injection: Inverter will shutdown if the DC component in the AC current
is over the limit.
 RCMU: If there is a leakage current between the input and output which
exceeds the limit, inverter will shutdown immediately.
 Reconnction Time: The time before the inverter connects to grid.
 Ramp-up Power: The rate of increase in the output power. (%/min)
