Safety
Read this first
Follow the instructions in this manual. These instructions are key to the installation and maintenance of the SG
Ready Relay. To ensure the safe installation and operation of the SG Ready Relay, note the following safety
symbols that appear throughout this document to indicate dangerous conditions and important safety
instructions.
DANGER:
This indicates a hazardous situation, which if not avoided, will result in death
or serious injury.
WARNING:
This indicates a situation where failure to follow instructions may be a safety
hazard or cause equipment malfunction. Use extreme caution and follow
instructions carefully.
NOTE:
This indicates information that is very important for optimal system operation.
Follow instructions closely.
Safety instructions
DANGER:
Risk of electrocution!
Do not attempt to repair the SG Ready Relay. It contains no user-serviceable
parts. Tampering with or dismantling the SG Ready Relay will void the
warranty. If the equipment fails, contact Enphase Customer Support
(enphase.com/support) for assistance or replacement equipment.
DANGER : Risk
of electric shock
Do not use SG Ready Relay in a manner not specified by the manufacturer.
Doing so may cause death or injury to persons, or damage to equipment.
All sources to equipment being serviced must be disconnected external to
the device. In particular, the storage system may energize conductors, so
storage circuits must ALWAYS be isolated via circuit breaker or disconnected
before working on any portion of the system.
Be aware that installation of this equipment includes risk of electric shock.
DANGER : Risk
of electric shock. Risk
of fire
Only use electrical system components approved for wet
locations.
Only qualified personnel should troubleshoot, install, or add parts to the
SG
Ready Relay
.
Ensure that all wiring is correct and that none of the wires are pinched or
damaged.
Do not work alone. Someone should be in the range of your voice or close
enough to come to your aid when you work with or near electrical
equipment. Remove rings, bracelets, necklaces, watches etc. when working
with batteries, photovoltaic
modules, or other electrical equipment.

WARNING:
Before installing or using the
SG Ready Relay , read all instructions and
cautionary markings in the technical description and on the components.
NOTES:
Using unapproved attachments or accessories could result in
damage or
injury.

Preface
Scope of this document
This document provides the necessary information to configure and setup the supported heat pump for use
with the IQ Energy Router+ and the Enphase Energy System (EES).
For further information regarding the installation of the IQ Energy Router+ package, please review the Quick
Install Guide available in the Enphase documentation center.
This document has been developed after obtaining permission from Glen Dimplex. Observe the safety
instructions from Glen Dimplex with respect to installation, operation, and maintenance from the heat pump
and its equipment which you can find in References at the end of this document. The information from Glen
Dimplex might change and hence, when in doubt, contact Glen Dimplex.

Optimizing the heat pump using the SG Ready interface
Connect the Enphase IQ Energy Router to a supported heat pump using the SG Ready interface. Once
configured, the IQ Energy Router can optimize the operation of the heat pump to increase the self-
consumption of solar energy and lower the use of energy from the public electricity grid.
NOTE:The SG Ready signal is purely a recommendation to start the heat pump. The Enphase IQ
Energy Router can never force the heat pump system to turn ON or OFF. The comfort level of the
user is always safeguarded, and the correct operation of the heat pump system is ensured.
Performing the prerequisite checks
Perform the following prerequisite checks before proceeding with the wiring and configuration of the heat
pump equipment and SG Ready Relay:
•Follow the Enphase Energy System installation and commissioning instructions in the Enphase
Installer App.
•Activate the Enphase IQ Energy Router and configure it such that it can detect and connect to the
other components such as SG Ready Relay or Energy Meter referred to in this documentation.

Hardware requirements
Install the following hardware before you proceed with this document:
•Enphase hardware
oIQ Gateway
oIQ Battery
oIQ Microinverters
•Enphase Energy System hardware (hard copy guides provided in the box)
oIQ Energy Router
oEnergy Meter
oSG Ready Relay
•Heat pump system
oSupported Dimplex heat pump system
NOTE: Install and connect the SG Ready Relay and Energy Meter to the same LAN of the customer.
Connecting the heat pump and the SG Ready Relay
DANGER: Electric shock. Do not touch live components as it can lead to dangerous injuries due to
electrical current. Please disconnect the whole system before working on it with a separate fuse or
via the main fuse, check that no voltage is present afterwards and secure against switching on again.
There is a risk that some components still carry voltage after the main voltage has been switched off.
To set up the SG Ready functionality, it is needed to connect the SG Ready Relay with the heat pump indoor
unit or controller of the heat pump via wires. Depending on the heat pump indoor unit or controller the cable
connection might be different.

2. The SG Ready signal is transferred from the SG Ready Relay to the two digital inputs of the heat pump
manager. You can find the heat pump manager on the top of the heat pump (refer to the following
figure).
Source: Dimplex
3. The usable connectors on the heat pump manager are:
•Digital inputs N1-J5/ID1 & N1-J5/ID2
•X3/G
4. Connect the wires from the SG Ready Relay with the digital inputs N1-J5/ID1 & N1-J5/ID2 and X3/G.
The colors of the wires are not relevant.

5. After the wiring is completed, close the heat pump unit by placing the metal cladding back on and
securing it.
Power on
After performing all the steps above, you can apply power by closing the breaker for the heat pump, the Energy
Meter, and the SG Ready Relay, and then proceed to the configuration step below.
Configuring the heat pump system controller
After the installation is done, the SG Ready function must be activated and configured on the heat pump
system controller.
Depending on the system controller of the heat pump, the activation and configuration of the SG Ready
function can be different.
1. Go to the display of your heat pump.

7. Select “Smart-Grid”
8. Click the icon to go back to the home page.
Validating the configuration
To check if the SG Ready functionality is wired and configured correctly, perform a final test by following the
steps:
1. Go to the SG Ready Relay and press the “Select” button (refer to the figure) multiple times until LED 2
is flashing.
Source: SG Ready Relay
2. When LED 2 is flashing press and hold “OK” for one second.
3. Now the SG Ready operating state “3” should be enabled.
4. Go to your heat pump manager and enter the extended installation level by pressing the MENU and
ENTER buttons simultaneously for five seconds.
5. Go to “Inputs”.
6. Check if “thermostat hot water” is showing “Contact closed”.
7. Check if “thermostat swimming pool” is showing “Contact open”.
8. Then go back by clicking the ESC button.
9. To end the test, click on the SG Ready Relay again the “Select” button, select LED 2, and click “OK”
for 1 second. Now the LED 2 should glow red.
10. The test and commissioning were successful.
