Chapter 2: Meter Installation

The StorEdge solution requires connecting a meter f or S mart Energy Management applications, such as
export limitation and maximizing self-consumption.
The meter type (single or three phase) and number of current transformers (CTs) should be selected per
the grid connection and energy management application rather than according to the inverter model.
The C Ts are supplied with 2m twisted pair wires for connecting the CTs.
To install the SolarEdge meter, refer to to the installation guide supplied with it:
http://www.solaredge.com/files/pdfs/solaredge-meter-installation-guide.pdf.
The meter is connected to the inverter using RS485.
RS485 wiring specifications:
Cable type: Min. 3-wire shielded twisted pair (a 4-wire cable may be used)
l
Wire cross-section area: 0.2-1 mm²/ 24-18 AWG (a CAT5 cable may be used)
l
NOTE
The inverter RS485 bus should be connected to the battery (via the StorEdge interface) and meter.
Connecting multiple inverters (or an external logger) with RS485 master-slave connection requires an
RS485 Expansion Kit (available form SolarEdge Refer to
http://www.solaredge.com/files/pdfs/RS485_expansion_kit_installation_guide.pdf).
To connect the meter to the inverter:
1. Remove the seal from one of the openings in communication gland #2 at the bottom of the inverter
and insert the RS485 wires from the meter through the opening.
2. Pull out the 9-pin RS485 connector located on the communication board.
