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.
