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.

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.S P Version 3 0 Wireless Home Energy Manager - Step One

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.S P Version 3 0 Wireless Home Energy Manager - Step Two

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.S P Version 3 0 Wireless Home Energy Manager - Step Three

Step Four:

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.S P Version 3 0 Wireless Home Energy Manager - Step 6

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.S P Version 3 0 Wireless Home Energy Manager - Step7

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.

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.S P Version 3 0 Wireless Home Energy Manager - Step9

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)S P Version 3 0 Wireless Home Energy Manager - Step10

Note:
There must be no electrical connection to the Live conductor.S P Version 3 0 Wireless Home Energy Manager - Step11Maintain 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)S P Version 3 0 Wireless Home Energy Manager - Step12

Step Twelve:
Check connectionS P Version 3 0 Wireless Home Energy Manager - Step13

Check the Wireless Energy Manager is connected to the charger.
Status should be ‘Connected’.
Step Thirteen:
Check ConnectionS P Version 3 0 Wireless Home Energy Manager - Step14

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
S P Version 3 0 Wireless Home Energy Manager - Optional Steps
