Enabling Safedc - SolarEdge Key Bedienungsanleitung

After 5 seconds, the string output voltage Vo is displayed
(xxx.x). The SafeDC mode is now disabled and the voltage of
each power optimizer equals the voltage of the module.
WARNING!
The DC cables carry a high voltage and the power
optimizers no longer output a safe 1V output.
PROCEED WITH CARE!
7
Disconnect the string cables and connect them to the inverter.
8
Perform the commissioning steps of the inverter as described
in its manual. When connecting to inverters without SMI,
pairing is not required.

Enabling SafeDC

When connecting power optimizers directly to a SolarEdge inverter
or to a Safety and Monitoring Interface, SafeDC should be enabled to
ensure that all power optimizers are set to a 1V DC output voltage
before connecting to SolarEdge inverter or SMI.
NOTE:
Enable the safeDC for each string individually.
►
To enable SafeDC:
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).
