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 inverter connected to the battery (SolarEdge inverter in Figure 17: Backup Power Only

- Large residential PV systems).

2 Connect SolarEdge inverter RS485-1 port to SolarEdge standard inverter RS485-1 port using an RS485 twisted pair cable.

Terminate both sides.

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.

6 SolarEdge standard Inverter does not require communication configuration.

► To configure the system:

1 Configure the StorEdge inverter battery and backup power as described in the Basic Configuration page 20.

2 Configure the second SolarEdge inverter as described in http://www.solaredge.com/files/pdfs/products/inverters/se-single-

and-three-phase-inverter-user-manual-na.pdf.
