Kyran Lacey, our NAPIT-certified electrician, recently completed a comprehensive EV charger upgrade for a homeowner in High Wycombe's HP13 5EL postcode. We replaced an older EV charger with a new Myenergi Zappi V2.1 7.4kW untethered charger, significantly improving the property's electrical infrastructure and charging capabilities.

Why Did This High Wycombe Homeowner Need an EV Charger Upgrade?

The existing installation was five years old and no longer met current electrical safety standards. Our site survey revealed critical gaps in the original setup, including inadequate consumer unit protection and limited charging capacity. We recommended a complete upgrade to ensure safe, efficient electric vehicle charging.

What Does a Zappi Installation in High Wycombe Involve?

Our installation process included replacing the existing consumer unit with a dedicated four-way EV consumer unit. We installed a 40 amp RCBO, 100 amp mains cut-out, and a surge protection device. These upgrades provide enhanced electrical safety and future-proofing for potential three-phase property transitions.

How Does the New Zappi Charger Improve Home Charging?

The Myenergi Zappi V2.1 offers significant improvements over the previous charger. It supports up to 22kW charging (when connected to a three-phase supply), includes advanced wireless connectivity, and integrates with the homeowner's local Wi-Fi network. We also connected the charger to a Harvey wireless CT device for enhanced monitoring.
