The Eco Harmony EV Charger Product Finder is a free, interactive web application designed for UK-based electricians, EV charger installers and homeowners. It serves two core purposes: (1) helping users find the correct BS 7671 compliant electrical protection products for any EV charger installation, and (2) providing detailed feature-by-feature comparisons of Simpson & Partners EV chargers against leading competitor brands across Home, Holiday and Business product series.
This tool is designed for multiple audiences:
The product finder follows a decision tree based on three key inputs:
Based on these inputs, the tool recommends the exact consumer unit or protection board needed, with full product details, links to purchase, and detailed reasons explaining why each product was recommended.
The most important factor is whether the EV charger has built-in PME protection. Under BS 7671 (the IET Wiring Regulations), EV charger installations on PME (TN-C-S) supplies require PEN fault detection to protect against dangerous voltages if the combined PEN conductor breaks.
Chargers WITH built-in PME protection (no external PEN fault device needed): Simpson & Partners Home Series (all variants), Simpson & Partners Holiday Series, Simpson & Partners Business Series, MyEnergi Zappi v2, MyEnergi Zappi GLO, Ohme Home Pro, Ohme ePod, Hypervolt Home 3, Hypervolt Home 3 Pro, Easee One, Easee Charge, Pod Point Solo 3, Pod Point Solo 3S, Zaptec Go, Zaptec Pro, EO Mini Pro 3, EO Genius, Project EV Apex, Project EV Pro Earth, Indra Smart Pro, Indra Smart Lux, Sync EV, EVEC 7.4kW, NexBlue Edge, Aurora Seren, SolarEdge Home EV Charger.
Chargers WITHOUT built-in PME protection (external PEN Fault Detection Board required): Tesla Wall Connector Gen 3, Wallbox Pulsar Plus, Wallbox Pulsar Max, Wallbox Commander 2, Sevadis MaxiCharger.

Users who don't know which charger they want can use the built-in Charger Advisor. It asks three questions: (1) Do you have a wall to mount the charger on? (wall mount vs freestanding), (2) Do you want a tethered cable or socket outlet?, (3) What power supply does the property have? (single phase vs three phase). Based on answers, it recommends the appropriate Simpson & Partners charger — either the Home Series Wall Mount or the Freestanding Home Series — in the correct phase and cable configuration. Both include built-in PME protection.
The tool includes an interactive charger comparison feature that compares Simpson & Partners chargers against competitor brands across three product series (Home, Holiday, Business) and six feature categories:

The multi-charger wizard handles commercial and multi-bay installations with 2-6 EV chargers. It recommends dedicated protection boards with individual RCBO protection per circuit (required by BS 7671), surge protection, and for three-phase installations, a TPN Distribution Board with 4P 125A main switch as the central distribution point. The tool warns when single-phase supplies may be insufficient for 3+ chargers and recommends a DNO supply upgrade to three phase.
For OEMs and custom charge point builders, the tool recommends one of four EVSE controllers: EPC 1.0 (entry-level, tethered, IEC 61851), EPC 2.0 Lite (socket + RFID + RS-485), EPC 2.0 Plus (4G/Wi-Fi/Ethernet + OCPP 1.6J + energy metering), or EPC 3.0 Smart (OCPP 2.0.1 + ISO 15118 Plug & Charge + dual-socket + advanced energy management). Selection is based on outlet type, connectivity needs and deployment scale.
