4. Connection, Power-up and local configuration
Device Connection: 1. Connect the DelREMO to RS485 MODBUS to which inverter and Energy meters are
connected. 2. Connect the sensors to the analog input port. 3. Connect the Ethernet cable from device to a local router [after configuration 2G
connection can be used]. 4. Power ON the device with the provided power adaptor.
Device configuration: 5. After DelREMO device boots up, configure the device for DHCP. 6. Note down the IP address displayed on the device screen.
Local portal Configuration: 7. From a PC/laptop in the same network open the web browser with the IP address
displayed on device. 8. Login with the admin username and password. 9. Configure inverters – see DelREMO 2V0 user manual for more details. 10. Configure Energy meters connected to MODBUS. 11. Configure time and interval. 12. Set the offset for connected sensors. 13. Set communication interface type - Ethernet / GSM. 14. Set the server URL and port number. 15. Restart the DelREMO device.
MODBUS Address scheme 1. If there is no energy meter, DelREMO can be connected with maximum 60 inverters. 2. Inverter id (1 to 30) should connect to RS485 Port1 and id (31-60) to RS485 Port2. 3. Maximum 5 supported Energy meter can be connected with DelREMO starting with device
id 41 to 45. Supported Energy meters: Table 2:
Make Model
Schneider EM6400
Schneider EM6400NG
Secure meters Elite440
4. Energy meters should be connected to RS485 Port2 only.

5. Data format Connection to DelREMO device is a TC/IP connection over internet. Data packets are part of the http post method over the TCP IP. Below is the structure of the post method http://ipaddress/log.csv?<MAC ID><data set> ipaddress – IP address of the server configured where data to be http posted. Log.csv – file name / format MAC ID – MAC ID of the device sending the http post data <data set> - one of the data set listed in this section. Following are individual data packets that will be sent by the DelREMO device during any of the post method transmission. All the data group is a different http post and are NOT combined together. Each of the parameter is a comma separated value, so the delimiter is ‘,’.

7. PC software tool for debugging. Hercules_3-2-8(TCP Server): This software is useful to check the connectivity and packet format sent by the client to server.
1. Open the software on the same system whose URL/ip address is configures as
server in the DelREMO. 2. Select TCP Server and provide the same port number as set in DelREMO. 3. Click Listen to start the server. Now you can view the Data packet posted by
DelREMO.
8. Trouble shooting
Page 20
DelREMO 2C0 Standalone Solar remote monitoring device SIG.
Unilog (UDP listener): This software is to view the UDP messages from the Delremo to Specified system. This software will work only if DelREMO and the System is in same local network.
1. Open the software, go to windows and click on “new window” to open another window. 2. On the right side top select “UDP Port”. 3. In “Server Port Settings” give the port number (default 1024), then connect to listen all
the UDP logs. 4. In the DelREMO local portal go to configuration -> ports -> DIP (Debug ip). Configure it
with the same IP where the Unilog software is running. Restart the DelREMO.
