Dual Zappi EV Charger
Installation in Barton Seagrave
Project Overview
This project involved installing two Zappi EV chargers at a residential property in Barton Seagrave. The household had two electric vehicles and needed both to be able to charge at home reliably. The challenge with dual EV charger installations is not just running two cables — it is making sure the property's electrical supply can comfortably support both chargers operating without overloading the supply.
Zappi chargers were chosen for this installation. Zappi is a popular choice for households that want smart charging control and compatibility with solar and home energy systems.
What the Client Needed
Two EV chargers — one per vehicle — installed in a practical external location with a clean finish. The client also wanted confidence that running both chargers simultaneously would not cause problems with the property's supply. That concern is entirely reasonable and something that should be assessed before any dual EV charger installation goes ahead.
Electrical Work Completed
Both Zappi units were installed and connected to dedicated circuits, with appropriate cable routes run from the consumer unit to the external installation point. The installation included all required protection to meet current wiring regulations for EV charging.
Load management was configured as part of the installation. This allows the two chargers to communicate and share the available supply capacity between them. Rather than both chargers drawing at full rate simultaneously — which could exceed the available supply — load management means the combined draw is kept within safe limits. In practice, this means both vehicles can still charge overnight; the charge rate adjusts automatically depending on what else is drawing from the supply at the time.
The external installation was kept tidy, with cable routes and containment chosen to give a neat result on the building.
Why Load Management Matters
It is worth understanding why load management is relevant for dual EV charger installs. A standard domestic supply has a finite capacity. A single EV charger drawing at full rate can use a significant portion of that. Two chargers doing the same simultaneously can push a supply into problems — nuisance tripping, supply issues or simply overloading the incoming fuse.
Load management removes that risk. The chargers are aware of each other and of other demand on the supply, and they adjust their draw accordingly. The homeowner gets two working chargers without having to upgrade their supply or worry about which vehicle to charge on a given evening.
Any household considering a dual EV charger installation should have the supply assessed first. Installing two chargers without that assessment is a false economy.

Testing, Safety and Handover
Both chargers were tested after installation, with all circuits verified for correct operation, protection and earthing. An Electrical Installation Certificate was issued on completion. The client was shown how both chargers operate and how the load management behaves when both vehicles are connected.
