Disabling Safedc - SolarEdge Key Bedienungsanleitung

Chapter 2: Using the SolarEdge Key

Disabling SafeDC

When connecting power optimizers directly to a non-SolarEdge
inverter without a Safety and Monitoring Interface, disabling the
SafeDC mode is required in order to reset the string before
connecting to the inverter.
NOTE:
Do not start the process of disabling SafeDC in case of low
battery.
NOTE:
Disable the safeDC for each string individually.
►
To disable the SafeDC mode:
1
If using add-on power optimizers (OPIxxx or PxxxI), make sure
each power optimizer is connected to the PV module, as
described in the SolarEdge Power Optimizers Installation Guide.
2
Connect power optimizers in a string, as described in the
SolarEdge Power Optimizers Installation Guide.
3
Connect a string of power optimizers to the SolarEdge Key (see
Figure 2).
4
Check that the string voltage (Vo xxx.x) is compatible with
the number of optimizers. When power optimizers are in
SafeDC mode, the Vo of each optimizer is 1V dc.
5
Long press SafeDC Disable. The screen displays IndOP and
then N / Y?
6
Short press the right button (Confirm) to continue or the left
button (Esc) to abort;
If you confirmed, the screen displays a backward countdown
and then displays #OP: xx
(xx= number of power optimizers in the string, between 0-30).
