10.4.1
rS485 Bus Communication
Here you can set the baud rate of the gateway for the RS485 communication. The
value should match the one of the inverter(s). The baud rate "19200" is set by default.
NOTICE
Please note, that the RS485 cable lengths is depending on the baud rate.
lengths should not exceed 1200 m if baud rate is 19200 (default value).
10.4.1.1 Wireless rS485 Modem
If you are using a RS485 wireless modem, please check the box.
10.4.2
delta database Connection
Every few seconds, the gateway is retrieving data from the SOLIVIA solar inverters. The
gateway stores these data and sends the average values to the database. Here you
can define the intervals in minutes of how often the average values and parameters are
sent to the database. By default, 15 minutes is set.
10.4.3
Force rS485 Bus Scan
The gateway does not know the number and addresses of connected inverters in
advance. It is assumed that each inverter connected to the bus already has its unique
address in the range [1, 254]. Address 0 is not allowed and 255 is the value used for
broadcasts.
NOTICE
Please check the SOLIVIA inverter user manual for instructions on how to select the
inverter ID.
Usually the list of inverters gets only longer. Every inverter that was once detected by
the gateway will remain in this list. By pressing the "Start" button the list will be can-
celled and the RS485 bus will be scanned for connected inverters.
The gateway is designed to connect to a maximum of 32 devices.
10.4.3.1 List of Connected SOLIVIA Solar Inverters
At power-up, start-up and each day at about noon the gateway scans the RS485 bus
for all connected SOLIVIA solar inverters.
•
Start from address 1 up to address 254. Address 0 is invalid and address 255 is
the broadcast address.
During the usual operation the gateway collects only the data of the inverters in the
inverter list. If a new inverter is connected at e.g. 2:00 pm, this inverter will only be re-
cognized after a new scan (latest the next day at about noon).
