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 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 shielded Ethernet cable (Cat5/5E STP)

may be used)

Wire cross-section area: 0.2-1 mm²/ 24-18 AWG (a CAT5 cable may be used)

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 may require an RS485 Expansion Kit (available

form SolarEdge; Refer to

kit_installation_guide.pdf).

To connect the meter to the inverter:

1. Remove the seal from one of the openings in communication gland at the bottom of the inverter and

insert the RS485 wires from the meter through the opening.

2. Pull out the R S485 connector located on the communication board.
