
Device Type is used to select the specific port configuration. The following devices are supported:

SolarEdge (default for RS485-1): Used when connecting to SolarEdge devices, such as: inverters,
SMIs or other gateways. By default, all SolarEdge devices are pre-configured as slaves on the
RS485-1 port.

Inv. Reader : Used for connecting to a non-SolarEdge inverter, in order to read its data and send
it to the monitoring portal. For a list of supported Non-SolarEdge inverters, refer to
http://www.solaredge.com/articles/se-supported-devices .

Revenue Meter : Used when connecting to an external revenue grade meter, in order to read
the meter data and send it to the monitoring portal. For a list of supported meters, refer to
http://www.solaredge.com/articles/se-supported-devices .

Non-SE Logger : Used when connecting to an external non-SolarEdge logger. The logger can
read SolarEdge inverters data for Non-SolarEdge monitoring purposes.

None (default for RS485-2)

Protocol:

When selecting a SolarEdge device, the following protocols appear under the Protocol option:

Slave (default)

Master

When selecting Device Type <Inv. Reader>, the Device Type <field> changes to
Device Type
<INV>

When selecting Device type <Non-SE Logger>, the Device Type <field> changes to
Device Type
<LGR> and the following protocol appears under the Protocol option:
SunSpec (default)

When selecting Device type <Revenue Meter>, the Device Type <field> changes to
Device Type
<MTR>
NOTE:
For other supported protocols, refer to http://www.solaredge.com/articles/se-supported-devices .

Slave Detect: Is used to initiate automatic detection of the slave SMIs connected to this master SMI.
The number next to the option is the number of SMIs that have been detected.
Creating an RS485 Bus Connection
The first and the last devices in the chain must be terminated. Do not terminate devices along the bus. Use
uses a four-wire twisted-pairs cable for the connection.
►
To connect the RS485 communication bus:
1
Open the SMI cover, as described in Appendix D: Opening and Closing the SMI Cover on page 51.
2
Remove the seal from one of the openings in communication gland #2 and insert the wire through
the opening.
