Chapter 1: Introduction
Terminology
The following terms are used in this document:
Export: The power injected to the grid.
Import: The power purchased from the grid.
Export/Import meter: A meter that is installed at the grid
connection point and measures the energy/power
exported/imported to/from the grid.
Consumption: The power consumed by the site.
Consumption meter: A meter that is installed at the load
consumption point and measures the energy/power
consumed by the site.
Self-consumption: The PVpower consumed by the site
and not fed into the grid.
Production: The power produced by the PV system.
Production meter: A meter that is installed at the inverter
output or site AC connection, or in the inverter (a built-in
revenue grade meter), and measures the energy/power
produced by the PVsystem or site.

Three-phase grid configuration types:
Wye: In a Wye ("Y") configuration, all three phases are
connected at a single neutral point. Wye systems utilize
five wires - three hot, one neutral and one ground.
Delta: In a Delta configuration, the three phases are
connected in a triangle. Delta systems utilize four wires -
three hot and one ground.

The SolarEdge Revenue Grade Energy
Meter with Modbus Connection
The SolarEdge Revenue Grade Energy Meter with Modbus
Connection (also referred to as “the meter”) enables measuring
the power and energy of the photovoltaic (PV)system.
The following meter models are available:
SolarEdge Meter Model Grid Type
SE-RGMTR-3D-208V-A Delta
SE-RGMTR-3Y-208V-A Wye
SE-RGMTR-3Y-480V-A Wye
The meter is used by the inverter for the following applications:
Production metering
Consumption monitoring
Export limitation
Smart Energy on-grid applications
The meter requires three Current Transformers (CTs). The CTs
are available from SolarEdge.
The SolarEdge inverter or the Commercial Gateway (CCG) reads
the exported/imported power from a meter installed at the grid
connection point or reads the consumption from a meter
installed at the load consumption point.

Meter Connection Options
In a single inverter system, the meter is connected directly to
the inverter.

Chapter 1: Introduction13

Figure 5: Single-inverter connection
In a multiple inverter system, two options are available:
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.
The meter is connected to one of the RS485 ports of a CCG.
The CCG’s second RS485 port can be used to create an
RS485 bus for communication between the inverters. This
option is illustrated in Figure 6 .

Installation Guidelines
AC wire specifications: 1.3 to 2.0 mm diameter / 16 to 12 AWG
stranded wire, 600 V, type THHN, MTW, or THWN.
RS485 wiring specifications:
Cable type: Min. 3-wire shielded twisted pair (a 4-wire
cable may be used)
Wire cross-section area: 0.2- 1 mm²/ 24-18 AWG (a CAT5
cable may be used)
NOTE
If using a cable longer than 10 m/33 ft in areas where
there is a risk of induced voltage surges by lightning,
it is recommend to use external surge protection
devices. For details refer to External Lightning
Protection on page 68. If grounded metal conduit are
used for routing the communication wires, there is no
need for a lightning protection device.
The meter is considered “permanently connected
equipment” and requires a disconnect means (circuit
breaker, switch, or disconnect) and overcurrent protection
(fuse or circuit breaker).
