Home EV Wallbox - Loading Balancing Setup Guide
Introduction
The loading balancing has been designed with ease of installation in mind. Its lightning-fast reaction time to overload
currents coupled with the fact that EV charging station records the power and energy from the CT-Meter means you
will improve on the safety of your installation while gaining insights into the energy usage of the property.
How it works
The Hypervolt works using a wired CT sensor which the installer must clip over the main incoming power feed into
the property. Please refer to the wiring diagram < Load Balancing Wiring Diagram >

Your property will have a maximum allowed total power consumption that can be configured inside your EV charging
station. Once installed and configured, the charger monitors this consumption in real-time. In the event that charging
would cause you to exceed the pre-set limit, we will then reduce the EV charging rate in order to protect your electrical
wiring and avoid blowing the fuse in your meter whilst continuing to charge your vehicle.
Wiring and Setting Up
CAUTION: make sure the EV Charging station is switched off and isolated from the mains before proceeding.
According to the Load Balancing Wiring Diagram, first pass the CT through the live wire of the main power line, then
connect the CT wire to the access terminal of the electric meter, and then connect the electric meter and the charging
pile together through the RS485 communication line.
Remember not to connect the direction of the RS485. On the contrary, the last meter needs to be connected to a
220VAC (± 20%) power supply.
APP Setting Up
Set your maximum overload current through the APP according to the fuse capacity of your household's total
incoming line (The current set by the APP is less than the actual main input fuse current)
