Sometimes, two or more rectifiers/inverters/charge controllers are deployed on a site for operational reasons. Therefore, Galooli allows the integration of two or more rectifiers into a single Galooli Elara gateway. As the Elara gateway only has one ethernet port, a ethernet switch can be used to accomplish the mission.

Required Equipment:
Computer
RS485 To USB Converter & two 0.5mm thick communication cables. The length of the cables is determined by the distance between the RS485 to the USB converter and the computer
Screwdriver (Slotted & Phillips)
SIM Card
SD Card
Elara Gateway
Power cables for the Elara gateway - two cables with a thickness of 0.5mm. The length of the cables is determined by the distance between the power supply and the Elara gateway
Power source for the Elara gateway - 12-60v
Elara Power & Connectivity
The full installation and configuration of the Elara gateway should be completed as described in the following documentation before moving on to the next step. Elara Installation and Configuration
CISCO Ethernet Switch Power
Power the CISCO Ethernet Switch as described in the following documentation before moving on to the next step. Ethernet Switch
Connection Between the Elara and CISCO Switch
With a straight ethernet cable, connect the Elara gateway ethernet port to port 1 of the CISCO ethernet switch. Connect rectifier device 1 and rectifier device 2 modules to ports 2 and 3 of the CISCO switch.
Elara Configuration
Open the Power Center.
For the first rectifierdevice, in the “Configuration” tab click on “Add SNMP ETH Device”. Choose the first rectifier' s device name and model. Ensure that all parameters are correct especially the “Device IP” and apply the changes.

The IP addresses in the images below are only examples. |
...
For the second rectifierdevice, you should perform the same action as you did in the first rectifierdevice, but the "Device IP" should be different, but within the same range.
...
Click on “Write Configuration” and “Reset”.
Ensure that the Elara gateway is connected to the computer.
Select the "Configuration" tab, click on "Group:_Device", and then double click one of the rows appearing under "Group:_Device". Set the "Network Gateway" and the "Elara IP" in the Elara configuration window so that they will be in the same range as the two rectifiers. Apply the changes.
As a result, both rectifiers and the Elara must be within the same range.Click on “Write Configuration” and “Reset”.

Device Configuration
Rectifier 1: Login to rectifier 1, ensure the device IP and gate way are set to Enter the internal configuration wizard for device 1 and 2 and ensure that both the IP address of the device and the Elara gateway are set to the same network range as in the Power Center. As an example:
Device 1 - 192.168.100.100 and 192.168.100.1Rectifier 2: Login to rectifier 2, ensure the device IP and gateway are set to
Device 2 - 192.168.100.102 and
Elara Gateway - 192.168.100.1101
Once all of the steps have been completed, the rectifiers devices should be able to communicate with the Elara gateway.
