EN Plus

Homeowners and PV owners

Charge at home on your own terms — off-peak, from your solar roof, and inside your contracted power.

Who

Who this is for

Private EV owners with a garage or driveway, increasingly with rooftop PV and a home energy system. They buy once, expect it to work for a decade, and want the installer to be in and out in a morning.

Problem

What gets in the way

  • A 7–22 kW wallbox can trip the main breaker if it ignores the rest of the house.
  • Solar surplus goes back to the grid at a poor tariff instead of into the car.
  • Public charging is expensive and unpredictable; night tariffs are not.
  • Consumer IoT devices are a security liability unless certified.

Solution

How EN Plus solves it

  • Single-charger load balancing: the wallbox limits its own current when household consumption approaches the contracted limit.
  • PV Green Mode starts charging when surplus exceeds 6 A; Mix Mode tops up with grid power below that threshold.
  • Scheduled charging windows in the app for low tariffs; device authorisation for family and friends.
  • Caro and Alvis are certified to ETSI EN 303 645 for consumer IoT security (UK standard).

Benefits

What you gain

Lower cost per kWh

Night-tariff scheduling and PV self-consumption, managed automatically from the app.

No panel upgrade

Dynamic load balancing keeps the home inside its contracted power without a new supply.

Designed for the wall

Caro Series won the Red Dot Award 2023. Three enclosure colours, cable or socket versions.

Two-year warranty

Standard across the EU & UK range, with 24/7 online support.

Business case

Why the numbers work

  • Home charging replaces the most expensive public kWh with the cheapest domestic kWh.
  • PV-coupled charging turns exported surplus into driven kilometres.
  • Installer-friendly back plates and pole-mount options reduce installation time and cost.

Implementation

How it is rolled out

  1. 1Choose cable or socket, 1-phase 7 kW or 3-phase 11/22 kW depending on the supply.
  2. 2Installer mounts the back plate, wires the supply and the CT clamp for load balancing.
  3. 3Pair with the app over Bluetooth/Wi-Fi; set schedules and PV mode.
  4. 4Optional: connect to the cloud platform for remote diagnostics.
