The meter is connected to an RS485 port of one of the inverters. If the inverter has a second RS485 port, use this port to connect between the inverters. If the inverter has only one RS485 port, use an RS485 Plug-In (available from SolarEdge) or ZigBee communication between the inverters.
Mount the meter either directly on a flat surface, or on a DIN rail using the DIN-rail clips supplied with the meter. 1. Carefully remove the terminal blocks on both sides of the meter. 2. Use the two mounting holes on both sides of the meter to mark the hole positions.

Configure the meter parameters as follows: Set CT/Phase Loss to <En> (enabled). In the sub-menu, for each CT and phase used by the meter, set the corresponding entry to <En> enabled. Set the CT rating to the value that appears on the CT: CT Rating è<xxxxA>. The default is 5 Amperes.
Contact SolarEdge Support. If the meter is connected at the load connection point or if the meter is used for production metering, check for reversed CTs, swapped CT wires, or CTs not matched with the lines. Disconnect power immediately! Check the line voltages and the meter ratings. The line voltage is out of range (Vac ±20%).
Meter functionality is supported in inverters with CPU versions 4.2.xxx and above. 1. From the SetApp main menu, select Communication, and select the port to which the meter is connected - RS485-1 or RS485-2. 2. Select Protocol è Modbus (Multi-Device) 3. Return to the RS485-x Menu and select Add Modbus Device è Meter.
