Inline Energy Meter with SolarEdge Energy Net Communications

Emission Compliance

This equipment has been tested and found to comply with the limits applied by the

local regulations.

These limits are designed to provide reasonable protection against harmful interference.

This equipment generates, uses and can radiate radio frequency energy and, if not

installed and used in accordance with the instructions, may cause harmful interference

to radio communications. However, there is no guarantee that interference will not

occur in a particular installation. If this equipment does cause harmful interference to

radio or television reception, which can be determined by turning the equipment off

and on, you are encouraged to try to correct the interference by one or more of the

following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and the receiver.

Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications not expressly approved by the party responsible for

compliance may void the user’s authority to operate the equipment.

CAUTION!

Where EN55011 Class A is deemed applicable, the following requirements apply:

This equipment is not intended for use in residential environments and may

not provide adequate protection to radio reception in such environments.

This equipment should be connected to inverters with a rated power > 20

kVA and is intended to be installed in a large photovoltaic power generating

system by a professional.

This equipment should be physically separated from residential

environments by a distance greater than 30 m, and can be equipped with

additional filtering if necessary.

Inline Energy Meter with SolarEdge Energy Net Communications

Chapter 1: The SolarEdge Inline Energy Meter

with SolarEdge Energy Net Communications

The SolarEdge Inline Energy Meter (also referred to as “the inline meter”) is used to

measure the power and energy of the photovoltaic (PV)system.

The inline meter:

Fits in a standard EUelectrical cabinet

Supports a direct connection of up to 65A per phase, for three phase and single

phase grid connections

Is supplied with integrated current transformers - eliminating the need to install

external CTs

The three phase inline meter (part number: MTR-240-3PC1-D-A-MW) supports both

single-phase and three-phase grid connections.

The single phase inline meter (part number: MTR-240-1PC1-DW-MW) supports single-

phase grids only.



NOTE

This installation guide provides instructions for configuration of the inline meter

using SetApp. To connect the inline meter to display inverters, purchase the

relevant communication board kit from SolarEdge. See

Energy Net Support

page 14 to select the required kit.

SolarEdge Energy Net Wireless Connectivity

The inline meter supports wireless communication with the inverter using the SolarEdge

Energy Net connectivity. To establish communications, the inverter must also support

SolarEdge Energy Net.

Alternatively, serial RS485 connectivity can be implemented.

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 at the site. Consumption power is calculated as

the sum of self-consumption power and import power.

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, and measures the energy/power produced by the PVsystem or site.

External production meter: A meter that is used for production metering of 3rd party

generators, or for AC coupling with non-SolarEdge inverters.

Site production meter: A meter that is installed at a SolarEdge inverter output, and

reads the energy produced by all the inverters at the site.

Site limit: The power level (in kW) that the inverter falls back to once an export limit

event is triggered.

Metering Applications

The SolarEdge inverter reads data from the inline meter, typically using one of the

scenarios illustrated in the figures below:

Production metering, using a meter installed at the output power connection of the

inverter. Production metering functions (inverter production, external production,

site production) are supported in software version 4.14.xx and above.

Export/import metering, using a meter installed at the grid connection point

Consumption metering, using a meter installed at the load consumption point

8 Metering Applications

NOTE

The AC wires connected to the main terminal block of the inline meter can be

swapped - allowing the grid to be connected to

either

the upper terminal

blocks or the lower terminal blocks. For further details, see

Installing the Inline

Meter

on page 17



NOTE

Up to three meters can be connected to a single inverter. Each meter should

perform a different function. Any combination of Energy Net and

Modbus/RS485 communication is supported.
