Two sets, one bus: the basic set (charge controller with DC-leakage sensor) and the smart set (plus a site controller, wired RS485 to a WiFi controller or wireless Matter over Thread). CE, from stock, open protocol.

- [Edge EV Charger controller (EVSE-C-3x32A)](https://edgetech.eu/electronics/evse-c-3x32a.md), € 125 excl. VAT: AC charge controller board for one Mode 3 charge point, up to 3×32 A (22 kW), with integrated relay drive, per-phase current and voltage metering, and Modbus RTU control. The board inside most EdgeTech-based chargers since 2021.
- [DC-leakage sensor (EVSE-X-DCD)](https://edgetech.eu/electronics/evse-x-dcd.md): The 6 mA DC-to-PE leakage sensor that is part of every EdgeTech charger and every electronics set. Separate hardware, not a separate product: it lets a Type A RCD be used upstream instead of a Type B (IEC 62752).
- [Edge Load Balancer (EVSE-SC-01)](https://edgetech.eu/electronics/evse-sc-01.md), € 145 excl. VAT: First-generation site controller. Measures the main connection with three CT clamps and dynamically limits up to 4 Edge charge controllers over Modbus so the site never exceeds its main fuse. WiFi to the EdgeTech platform and the MyCharger app.
- [Edge Smart Load Balancer (EVSE-SC-02)](https://edgetech.eu/electronics/evse-sc-02.md), € 145 excl. VAT: Current-generation site controller. Reads the DSMR/ESMR 5 smart meter through its P1 port, so it needs no clamps, sees import and export per phase, and dynamically limits up to 10 Edge charge controllers. Solar-surplus charging, WiFi, MyCharger app.
- [Matter over Thread set (MATTER-SET)](https://edgetech.eu/electronics/matter-set.md): The wireless smart set: our charge controller with a Thread module, a P1 meter reader on the smart meter, a Matter controller that runs the load balancing, and an optional SG-Ready module for a heat pump. All Matter 1.4 over Thread. Not CSA-certified; certification on the customer's request.
- [GridShield controller and receiver (GS-C-01 / GS-R-02)](https://edgetech.eu/electronics/gridshield.md), € 370 excl. VAT: ElaadNL-compliant GridShield over LoRa point-to-point: one hardware, two roles, sold as two products. The controller measures the main connection and sends the reduce signal; the receiver limits chargers over RS485 and other loads with two relays. Tested against ElaadNL's implementation in both directions. For neighbourhood congestion and for buildings, car parks and sites without a data cable.
- [ISO 15118 communication module (PLC-15118)](https://edgetech.eu/electronics/iso15118-module.md): An add-on for the smart charger: HomePlug GreenPHY on the control pilot for ISO 15118 digital communication with the vehicle. With 15118-20 vehicles it shows the state of charge while charging on AC and identifies the vehicle for authorisation. Expensive, on request; V2G under investigation.
- [NFC card reader (NFC-RDR)](https://edgetech.eu/electronics/nfc-reader.md): An optional card reader for the charger. Two modes: a Dutch laadpas over OCPP for public and semi-public charging with roaming billing, or any NFC card as a local lock and unlock with a whitelist managed by the owner.
