Energy Manager
Version 3.0
Introduction
The Wireless Energy Manager is a clever little device that enables S&P
chargers to home load balance and solar charge without using a wire connected
current transformer.
The Wireless Energy Manager uses high performance LoRa wireless technology to
deliver excellent signal penetration and range.
In normal operation the Wireless Energy Manager requires no power source. The
energy harvested from the measurement CT is used to charge an internal long-
life battery.
NOTE: When the Wireless Energy Manager is connected to a S&P charger it
operates with a DNO fail safe function.
Safety Disclaimer
This equipment should only be installed by a qualified electrician with an
understanding of the electrical and building regulations.
The installer and/or designer is responsible for the installation in its
entirety, any internal protection provided by the manufacturer must be
confirmed through commissioning and testing of the equipment installed.
Particular environments and locations may have an effect on internal
protection and the reliability of the equipment.
The installation instructions should be followed closely to ensure correct
installation and commissioning, failure to follow these instructions could
result in damage to the Wireless Energy Manager, existing installation or
supplier’s equipment.
Measurement Disclaimer
The wireless energy manager balances the electric vehicle (EV) charging load
and the home’s electrical load. It measures more accurately and responsively
when the home has high electrical demand.
This may cause some differences between the home energy consumption reading
and the smart meter reading.
For more accurate home energy consumption reports in the app, use the wireless
energy manager in powered long-range mode.
Installation Location
The S&P Wireless Energy Manager is to be installed internally or within an enclosure/weatherproof space.
Safety Notice
This equipment should be installed, repaired and maintained only by a
qualified person. S&P take no responsibility for any consequences arising out
of the use of this documentation.
A qualified person is one who has skills and knowledge related to the
construction, installation and operation of electrical equipment and who has
received the appropriate safety training to recognize and avoid the hazards
involved.
All applicable local, regional and national regulations must be followed when
installing, repairing and maintaining this equipment.
Read this guide carefully and examine the equipment to become familiar with
its operation.
List of Parts
- Wireless measurement and transmission module
- Wall mount bracket
- CT clamp x 1 (SINGLE-PHASE MANAGER)
- CT clamp x 3 (3-PHASE MANAGER)
- Live current direction antenna wire
- Installation guide
- USB-C Cable for charging
Compatibility
The Wireless Energy Manager – is compatible only with S&P chargers.
The unit has been pre-calibrated in the factory and does not require on site
calibration.
Warning: Only use the provided CT which has no burden resistor. Use of
a standard CT will damage the unit.
Range
The unit uses a high performance LoRa transmission technology.
Standard Mode
The transmission range from the Home Energy Manager to the charger in standard
mode is up to approximately 50m when penetrating some physical obstructions.
Long Range Mode
The transmission range from the Home energy manager to the charger in long
range mode is up to approximately 85m when penetrating some physical
obstructions.
This mode is only supported when using an external USB-C power supply.
Getting Ready
Ensure the EV charger is installed in the desired location before attempting
to pair.
Also check the latest firmware is installed on the charger before commencing
with the pair process.
Now you are ready to pair it with Home Energy Manager.
Note:
Be ready to pair the unit to the EV charger within the next 5 minutes. If the
Home Energy Manager is powered on for an extended period without harvesting,
the battery will run flat.
Step Two:
Hold the Wireless Energy Manager within 10m of the charger you want to pair it
to.
Step Three:
Open the S&P app, Click the top left three ☰ lines, then tap Installation
Menu. Select the charger you wish to pair with (should you have more than
one), select Installation Menu then select Smart Home Devices.
Step Four:
The unit will remain in pairing mode for 2 minutes.
Step Five:
Check screens for the pair process.
The Wireless Energy Manager will appear in the Wireless Devices menu. Select
‘Add’.
The Wireless Energy Manager will appear as ‘Connected’.
Step Six:
Move the paired Wireless Energy Manager to within 1m of the consumer unit.
Step Seven:
Terminate Wires: for Single-phase go to Step Seven (a) for Three-phase go to
Step Nine
Warning:
Only use the provided CT which has no burden resistor. Use of a standard CT
will damage the unit.
Step Seven (a):
Strip and terminate the antenna cable and attach alongside the live/Line
conductor.
Connect USB cable to a power supply.
Long Range Mode automatically activates as soon as the external USB-C power is
detected.
Step Eight:
Fit 1 x CT clamp around L1.
Wiring example (single-phase)
Step Nine:
3-Phase termination
Warning: Only use the provided CT which has no burden resistor. Use of a
standard CT will damage the unit.
USB-C connection for Long Range Mode only.
Connect USB cable to a mains mobile phone charger.
Long Range Mode automatically activates as soon as the external USB-C power is
detected.
Step Ten:
Fit the CT Clamps x 3 around L1, L2, L3 Wiring example (3-phase)
Note:
There must be no electrical connection to the Live conductor. Maintain
appropriate clearances from any connection to the live or neutral and check
that the insulation is undamaged.
This is an example of a typical Energy Manager antenna installation.
- The antenna wire must run alongside the live wire as shown. It can be held with Ty-wraps or tape.
- It can be on either the input side or the output side of the meter, whichever is more convenient.
- The length is not critical, but the longer the better.
- This example shows the minimum length.
- It must be attached to the Live/Line wire, not the Neutral. Do not run the remainder of the antenna wire alongside any other conductor, as this will weaken the signal.
- Do not leave any remainder wire as hanging coil. Keep wrapping around or carefully shorten it.
Step Eleven:
Wall mounting (optional)
Step Twelve:
Check connection
Check the Wireless Energy Manager is connected to the charger.
Status should be ‘Connected’.
Step Thirteen:
Check Connection
Check the Wireless Energy Manager is reading the right way.
When the home is not exporting to the grid, you should see a positive Power
Test reading.
When the home is exporting to the grid, you should see a negative Power Test
Reading. Handy Note:
If the readings are incorrect, simply select the Reverse Reading button to
flip the readings (no need to rewire the CT).
Optional Steps
Setup Home Load Balancing
- Select the Home Load Balancing setup option.
- Set the home fuse rating.
- Set the failsafe fuse rating.
How to get to test mode
To check the system or carry out regular maintenance, you may wish to put the
Wireless Energy Manager into test mode.
Press the PAIR button for more than 2 seconds to put the already paired
Wireless Energy Manager into test mode.
In test mode, you should see the Wireless energy Manager transmit test
messages every 10 seconds.
The Wireless Energy Manager will remain in test mode for 2 minutes.
All done!
