Verifying The Connection - SolarEdge SE3000H-US Installation Manual

To connect to the monitoring platform:
1. Designate a single inverter as the connection point between the RS485 bus and the SolarEdge
monitoring platform. This inverter will serve as the master inverter.
2. Connect the master to the SolarEdge monitoring platform via the LAN or ZigBee communication
option.
To configure the RS485 communication bus:
All inverters are configured by default as slaves. If r econfiguration is required:
1. Make sure the ON/OFF switch is OFF.
2. Turn ON the AC to the inverter by turning ON the circuit breaker on the main distribution panel.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the inverter cover is removed.
AVERTISSEMENT!
RISQUE D'ÉLECTROCUTION, ne touchez pas les fils non isolés lorsque le couvercle de l'onduleur est
retiré.
3. Use the internal buttons to configure the connection (slightly touch the black square buttons). To set
the inverter designated as master, select the following in the LCD menus:
Communication è Server è LAN, Z igBee, or CDMA
l
RS485-1 Conf. è Device Type è SolarEdge
l
RS485-1 Conf. è Protocol è Master
l
RS485-1 Conf. è Slave Detect
l
The system starts automatic detection of the s lave inverters connected to the master inverter. The
inverter should report the correct number of slaves. If it does not, verify the connections and
terminations.
4. Verify the connection of the master to the m onitoring platform, as described in the next section.

Verifying the Connection

After connecting and configuring a communication option, perform the following steps to check that
the connection to the monitoring server has been successfully established.
1. Close the inverter cover: Attach the inverter cover and secure it by tightening the screws with a
torque of 3.0 N*m/ 2.2 lb.*ft. For proper sealing, first tighten the corner screws and then the two
central screws.
2. If not already ON - Turn ON the AC to the inverter by turning ON the circuit breaker on the main
distribution panel and turning on the Safety Switch.
3. Wait for the inverter to connect to the SolarEdge monitoring platform. This may take up to two
minutes.
A status screen similar to the following appears on the LCD panel:

S_OK: Indicates that the connection to the SolarEdge monitoring platform is successful. If S_OK is not
displayed, refer to Troubleshooting Communication on page 62.
