EVSE-SC-02 Shipped
Edge Smart Load Balancer
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.
In short
The site controller EdgeTech ships today. Plug it into the P1 port of the smart meter and it knows, every second, what the whole installation draws or exports on each phase. From that it gives each charge controller a current limit, once per second, over RS485.
Because it reads the meter instead of clamps, it sees the direction of current. That makes solar-surplus charging work: the car is charged from what the roof produces, and the grid limit is respected at the same time.

Key facts
| Specification | Value |
|---|---|
| Charge points | Up to 10 EVSE-C-3x32A on one RS485 bus (8 recommended for sites with many simultaneous sessions) |
| Site measurement | P1 port of a DSMR 5.0 / ESMR 5.0 smart meter (Netherlands, Belgium); per-phase import and export power, per-phase voltage and current |
| Load balancing | Per-second current limit per charge point; site limit, solar mode and 1P/3P per socket configurable; minimum 6 A per car, start threshold 8 A |
| Solar charging | Surplus mode charges only on export; solar-assist mode tops up from the grid. Uses meter export values, not clamps. |
| Fieldbus | Modbus RTU master, RS485, 19200 8N1 (switches fresh charge controllers from 9600 automatically) |
| Bus cable | 3 × 0.75 mm² multi-core (stranded). No solid-core cable and no raw Ethernet cable in the terminals; Ethernet only with RJ45 connectors (adapter board on request) |
| Connectivity | WiFi IEEE 802.11 b/g/n, 2.4 GHz only; MQTT over TLS with a per-device pre-shared key |
| Module | WiFi module (2.4 GHz) |
| Supply | From the P1 port (meter must supply ≥ 250 mA) or 5 V via micro-USB |
| Dimensions | 88 × 90 × 25 mm, mounted next to the meter, not inside the distribution board |
| Setup | WiFi credentials via the Mode pinhole (hold 3 s) and the MyCharger app; restart by unplugging the RJ12 for 3 s |
| CE | EU declaration of conformity on request |
| Made in | Europe |
