MyEnergi Zappi Glo Installed in Seer Green

We recently installed a MyEnergi Zappi Glo EV charger at a home in Seer Green, HP9 2XU. The homeowner's existing charger had failed after five years of reliable service, and they wanted a replacement that would work seamlessly with solar panels they're planning to install next year. One of our NAPIT-certified electricians handled the full replacement, including repositioning the cable entry and upgrading the electrical infrastructure to support smart charging. The customer was delighted with how quickly we commissioned the system and showed them how to use the app to monitor their charging in real time.

Why did this Seer Green homeowner choose the MyEnergi Zappi Glo?

The customer already understood the benefits of home EV charging — they'd been using their old charger for five years. When it started failing, they didn't want just any replacement. They chose the Zappi Glo specifically because they're planning to install solar panels in the coming months and wanted a charger that would integrate perfectly with their new solar system.

The Zappi Glo is designed to work with solar generation and battery storage. This means next summer, when their solar panels are producing excess energy, the charger can automatically draw that free power to charge their car. It's a genuine investment in reducing their energy bills and their carbon footprint. The customer understood this from the start — they weren't just replacing a broken charger, they were future-proofing their home energy ecosystem.

What made this installation different from a standard charger swap?

On the surface, this looked straightforward. The cable run was only 3.5 metres from the garage to the charger location on the outside garage wall. The incoming supply and fuse board were both in the garage, so there was no need for long cable runs or complex routing through the house.

But the old charger had to come out first, and that revealed a challenge. The original installation had used a rear entry cable that came out much lower on the wall than we needed for the new Zappi Glo. The old setup had fed the cable into a Whizz box, then run it up to the charger — a messy arrangement that wouldn't work with our new installation.

We repositioned the rear entry point higher up the wall to suit the new charger's location. This meant drilling a new hole and making good the old one. It sounds simple, but it's the kind of detail that separates a tidy, professional installation from a botched job.

Many Chilterns properties — especially older Victorian and Edwardian homes in Seer Green — require careful cable route planning from the fuse board to the garage or driveway. We assess all of this during the free in-person site survey before any work is agreed.

How did we handle the electrical infrastructure?

The customer had a 100 amp fuse, which was perfect for EV charging. However, we needed a safe way to isolate the charger supply without cutting off their smart meter. This is where the Henley blocks came in.

We fitted a double pole isolator using Henley blocks before connecting the new EV charger. This gave us a dedicated isolation point for the charger circuit, separate from the main supply. We arranged this with their energy provider before we arrived on site — this is standard practice and ensures everything is done safely and to regulations.

Once the isolation was in place, we ran the 3.5 metre cable through the garage wall to the new dedicated EV consumer unit. The power came from the Henley blocks, giving the customer a clean, safe electrical setup that's ready for future upgrades like solar panels or battery storage.

What happened during commissioning?

Once the Zappi Glo was installed and wired in, we commissioned the system and showed the customer how to use the app. This is where the real value of a smart charger becomes clear.

We demonstrated how the app lets you monitor exactly how much power you're drawing from the grid in real time. To show them how it works, we turned on the kettle and watched the app display the kilowatts being pulled from the supply. Then we switched it off and showed them the drop. It's a simple demonstration, but it helps homeowners understand exactly what their charger is doing and how they can use it to manage their energy.

The customer was impressed by how quickly we got everything up and running, and they were grateful that we took the time to explain the app properly. They now understand how to use it to monitor their charging, and they're ready to integrate it with their solar panels when those are installed next year.

If you're thinking about solar panel installation, a smart charger like the Zappi Glo is the perfect partner. You can also combine it with battery storage to store excess solar energy and charge your car from your own power.

How long did the installation take?

This was a standard domestic EV charger installation, so it took 2-4 hours from start to finish. The short cable run, straightforward garage location, and pre-arranged electrical work with the energy provider meant there were no delays or complications. We arrived, removed the old charger, repositioned the cable entry, installed the new Zappi Glo, and commissioned it all in one visit.

The speed wasn't about rushing — it was about planning. Because we'd done a proper site survey beforehand and arranged everything with the energy provider, we knew exactly what we were doing when we arrived. No surprises, no callbacks, no half-finished jobs.

What's next for this Seer Green home?

The customer is now ready for their solar panel installation. When those panels go in, the Zappi Glo will automatically detect excess solar generation and can charge the car for free during the day. If they add battery storage later, they'll have even more flexibility — they can store solar energy and use it to charge overnight or during peak rate periods.

This is what future-proofing really means. The customer didn't just replace a broken charger. They installed a smart system that will work with their home's energy for years to come.
