Verifying the Connection

After connecting and configuring a communication option, perform the following
steps to check that the connection to the Monitoring platform has been successfully
established.
1. If the Synergy Manager cover is not closed, close it: Attach the cover and secure it
by tightening the screws with a torque of . For proper sealing, first tighten the
corner screws and then the two central screws.
2. Commission the inverter as describe in "Activating, Commissioning and Configuring
the System" on page 43.
3. Access SetApp and select Status from the Configuring screen.
4. In the Summary section, under Server Comm., make sure S_OK is displayed
together with the selected communication option.
5. Scroll down to the Communication section and check that the communication
options are as required.

Alternative Power Source
Energy-generation systems (such as PV inverters) connected to the grid may consist of
different types of energy generating sources.
In some cases, when grid power is disconnected, PV inverters operate in parallel with
other voltage sources, such as generators.
When inverters operate concurrently with generators, they may be subjected to voltage
and frequency fluctuations that exceed trips, which are preset according to regional
grid connection requirements. To support simultaneous operation of the inverter and a
generator, the inverter extends its Voltage and frequency operating range once it
receives a Power Reduction Interface (PRI) signal indicating that grid power is
unavailable ("Alternative Power Source mode"). When the grid power is restored, the
inverter automatically reverts to its default country setting, which includes the original
Voltage and frequency operating range.
Figure 36 , shows an Example of Alternative Power Source System.
