Large Residential PV Systems
For residential sites with large PV systems, a StorEdge inverter and a SolarEdge single phase inverter may be installed together.
The StorEdge inverter manages the battery and functions as a PV inverter, and the second inverter is used for production of the
additional PV power. During power outages, the StorEdge inverter provides power to backed-up loads, and the second inverter
remains shut down until the grid is back.
An RS485 Expansion Kit (available from SolarEdge) is installed in the inverter connected to the battery.

► To configure inverter RS485 Communication:
1 Install the RS485 Expansion Kit in the StorEdge inverter.
2 Connect the StorEdge inverter RS485 Expansion port the second inverter’s RS485-1 port using an RS485 twisted pair cable.
Terminate both sides. From the StorEdge inverter:
3 Select Communication  RS485-E Conf  Enable. Press Enter to continue.
4 Select Protocol  Master
5 Select Slave Detect. Verify that the inverter reports the correct number of slaves.
The second inverter does not require communication configuration.
► To configure the system:
1 Configure the meter, battery and backup power of the StorEdge inverter as described in the Basic Configuration on page 8.
2 Configure the second inverter as described in http://www.solaredge.com/files/pdfs/products/inverters/se-single-and-three-
phase-inverter-user-manual-na.pdf.
► To set up Smart Energy Management:
After configuring the meter, battery and backup power, proceed with maximizing self-consumption or charge/discharge profile
programming on StorEdge inverter as described in the Basic Configuration on page 10.
► To verify communication:
Verify communication as described in the Basic Configuration on page 11.
