The energy manager allows the home 7 charger to monitor the energy usage of your home and adjust its charging rate so as to prevent your power supply from tripping.
This feature is known as load management or load balancing.
You will also need an energy manager if you want to have the solar monitor installed alongside your EV charging point.
The wired energy manager requires an extra cable feeding from your home charger to your power supply, which might look unsightly if they are both a long way from each other.
The wireless energy manager however does the same job as the wired energy manager but wirelessly using a radio signal.
If your home EV charging point is less than 10 metres away from your property's power supply, then we recommend going with the wired energy manager as it's cheaper and easier to hide the cable route.
