Chapter 1: Introducing the
SolarEdge Key
The SolarEdge Key is a service tool that is used to enable power
optimizers to work with non-SolarEdge inverters without installing
any additional hardware. In order to work with non-SolarEdge
inverters, power optimizers must support IndOP™ (Independent
Optimization); the part number of the power optimizer should start
with OPI, OPJ, OPxxx-LVJ or PxxxI.
All power optimizers provided by SolarEdge have the SafeDC™
feature enabled: When connected to a PV module, these power
optimizers output a safe voltage of 1VDC until they are paired either
with a SolarEdge inverter, or with the SolarEdge Safety & Monitoring
Interface (SMI), and until power production has started. Refer to
SolarEdge Power Optimizers Installation Guide for more details.
When connecting PV strings with power optimizers directly to a non-
SolarEdge inverter without a Safety and Monitoring Interface, SafeDC
must be disabled before connecting the string to the inverter.
The SolarEdge Key is used to configure power optimizers to one of
the following modes of operation:
SafeDC™: When the power optimizer is connected to a PV
module, its output voltage is limited to a safe voltage of 1V DC
until the optimizer is connected and paired with SolarEdge
inverter or with SMI. When the SolarEdge inverter/SMI are
operating, the power optimizer’s output voltage raises above
1V DC and the optimizer provides power. When the SolarEdge
Inverter / SMI are turned off, the power optimizer’s output
voltage is back to a safe voltage of 1V DC.
SafeDC Disabled: When the power optimizer is connected to a
PV module, its output voltage is limited to the open circuit
voltage (Voc) of the connected PV module.

into the battery compartment and close the cover.
4Press the ON/OFF button ( ) to turn the SolarEdge Key ON. If
LOW BAT appears, replace batteries.
5Press the ON/OFF button to turn the SolarEdge Key OFF. The
message End appears on the LCD and then the SolarEdge Key
turns OFF.

1Connect the string cables to the two connectors at the bottom
of the SolarEdge Key (see Figure 1).
2Press the ON/OFF button. The string voltage appears on the
LCD screen:
V o X X X . X

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:
1If 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.
2Connect power optimizers in a string, as described in the
SolarEdge Power Optimizers Installation Guide.
3Connect a string of power optimizers to the SolarEdge Key (see
Figure 2).
4Check 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.
5Long press SafeDC Disable. The screen displays IndOP and
then N / Y?
6Short 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).

Chapter 2: Using the SolarEdge Key
SolarEdge Key User Guide MAN-01-00131-1.2

English
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!
7Disconnect the string cables and connect them to the inverter.
8Perform 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:
1If 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.
2Connect power optimizers in a string, as described in the
SolarEdge Power Optimizers Installation Guide.
3Connect a string of power optimizers to the SolarEdge Key (see
Figure 2).

4Long press SafeDC Enable. The screen displays SafeDC and
then N / Y?
5Short 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 strings, between 0-30).
6After 5 seconds, the string output voltage Vo is displayed
(xxx.x).
The SafeDC mode is now active and the voltage of each power
optimizer is 1V. The string voltage equals the number of power
optimizers (less than 30V). When connecting to inverters with
SMI, perform the Commissioning steps as described in the
SolarEdge SMI Installation Guide, available on the SolarEdge
website at
http://www.solaredge.com/files/pdfs/products/inverters/guid
es/se_installation_guide_safety_monitoring.pdf.
All the power optimizers must be logically paired to the SMI.
The power optimizers do not start producing power until they
are paired with an SMI.
