Connecting to a datalogger via RS485

If you need to wire dry contacts, digital inputs
or RS485, it is recommended to do this in a dry
environment and before you hang the inverter
onto the wall.
Reasons for this are:
►
You will have to remove the covers from the
connection ports. Water could leak into the
inverter.
►
The terminal blocks inside are not easily
accessible.

RS485 is used to connect the inverters of the PV plant via a data-
logger to a monitoring system.
For connecting RS485, terminals 3/4 or 5/6 are used. It does not
matter which pair of terminals you use. The second pair you only
need when you connect multiple inverters via RS485.
If you want to use SOLIVIA Monitor, the Internet based monitor-
ing from Delta, you will also need a SOLIVIA M1 G2 Gateway.
Default baud rate is 19200 which can be changed on the inverter
(see chapter “Setting the baud rate”, p. 19).
