SolarEdge Inverters - SunSpec Logging - Technical Note
The Commercial Gateway should report the correct number of Follower inverters. If it does not,
verify the connections and terminations.
3.
Use RS485-2 to connect the Commercial Gateway to the non-SolarEdge monitoring device.
Configure the RS485-2 bus settings as follows,
using the device display
:
Communication RS485-2 Conf Protocol SunSpec (Non-SE Logger)
The Commercial Gateway device ID is irrelevant for communications, but needs to be set to a
different ID than the one set for the inverters.
Communication RS485-2 Conf Device ID [use one of the higher IDs (e.g. 247) to make sure it
is out of scope]
The default baud rate is 115200 bps. If a different baud rate is required, select: Communication
RS485-2 Conf Baud Rate
4.
Make sure the device ID of the non-SolarEdge monitoring device is different from all other
device IDs configured in the inverters and gateways.
5.
Connect the Commercial Gateway to router via the Ethernet interface and configure the
following settings
using the device display
:
Communication Server LAN
Communication LAN Conf Set DHCP [Select Enable for DHCP or Disable for static IP
configuration]
For Static DHCP setting, configure as follows:
Communication LAN Conf Set IP [Set inverters’ IP]
Communication LAN Conf Set Mask [Set inverters’ subnet mask]
Communication LAN Conf Set Gateway [Set inverters’ gateway]
Communication LAN Conf Set DNS [Set inverters’ DNS]
6.
If the router is connected to the server, select Commissioning Status and verify that
“S_OK” is displayed on the Status page.
MODBUS over TCP Support
MODBUS/TCP uses the Ethernet media in physical layers to carry the MODBUS message
handling structure and can support a large number of devices in one network; it is easier to
integrate into the Local Area Network (LAN) of a company, so it is the choice of more and more
customers.
Here, it is used for remote 3rd party monitoring and control. MODBUS TCP is agnostic of the
server connection. It works only over LAN. When configured, MODBUS TCP does not initiate a
connection - the server waits for a client to connect. Only one connection is supported.
NOTE
The MODBUS TCP function is disabled by default. When enabled, it supports TCP port 1502 by
default. Port number can be reconfigured.
