Installing the Inverter
SolarEdge Installation Guide – MAN-01-00002-1.6

The following describes each connector, the wire requirements and gauge of its
associated cable. All the Single Phase Inverter connectors are located at the
bottom of the inverter, as described below:
ON/OFF Switch:
Turning this switch ON starts the operation of the power
optimizers, enables power production and allows the Single Phase Inverter to
begin exporting power to the utility grid. Turning it OFF reduces the power
optimizer voltage to a low safety voltage and inhibits exportation of power.
When this switch is OFF, the inverter control circuitry remains powered up.
LCD Button:
Pressing this button lights up the LCD for 30 seconds. In
addition, you can press this button to access configuration menu options, as
described on page 98.
RS232 Connector:
•
Provides a configuration, control and management connection to a
locally connected PC or laptop, or to an external modem for connection
to the SolarEdge Monitoring Portal. You may refer to the
Creating an
RS232 (UART) Connection
section on page 69 for a description of how
to set up this communication option to the SolarEdge Monitoring server.
You may refer to the
SolarEdge Monitoring Portal User Guide
for more
information about the monitoring capacities.
Other Communication Options (Ethernet (LAN), RS485 or ZigBee):
Three
other types of communication options can be used to connect the inverter to the
SolarEdge Monitoring Portal. They are installed through the three cable glands.
You may refer to the
Chapter 6
,
Setting Up Communication
on page 66
for a
description of how to set up these communication options to the SolarEdge
Monitoring server.
NOTE:
RS485 connection is not available on the SE3000.
AC and DC Conduits:
Conduits must be rainproof if installed outdoors and
size 3/4".
AC and DC Internal Wiring:
Each of the AC wires (Line1, Line2, Neutral
and GND) and DC wires (DC+ and DC-) must be a 75°C or higher copper
wire with a cross-section of AWG10-AWG6 (8-16 mm2).
