NeLeSo Edge S · Compact Appliance
For sites with up to 25 charge points: underground car parks, commercial yards, retail branches or campsites. Edge S is a compact industrial NPU box – 12–24 V DC, control-cabinet mount – bringing the OCPP server, dynamic load management and AI anomaly detection to where your charge points are.
Use cases
Wherever charging demand exceeds connection capacity – and nobody wants to install a server rack.
Company cars, delivery vans and employee vehicles charge on the same connection as the workshop and sales floor. Edge S measures the operational load and gives the charge points exactly the budget that is currently free – no expensive grid upgrade.
Up to 25 parking spaces with wallboxes on the building's existing supply – shared fairly instead of tripping breakers. The device sits in the meter cabinet, works offline-first and needs no cloud to keep charging.
A real project: 8 chargers, 180 pitches, a restaurant and 60 kW of PV on a 180 kW grid connection. One Edge box in the control cabinet balances the entire site – see the diagram below.
From the field · Load management
The campsite case: Edge S live-measures the load of pitches and restaurant and adjusts the charger budget dynamically – at noon, PV surplus flows into the vehicles; during the evening restaurant peak, charging is throttled; at night, the most capacity is free.
Feature set
The OCPP server runs on the device, not in a data centre. Your wallboxes connect directly on the local network – vendor-independent.
Meters and energy measurement via Modbus RTU/TCP, SunSpec and EEBUS: Edge S knows the site load and continuously distributes the free budget across the charge points.
When your PV system produces a surplus, it flows into the vehicles first – including a forecast of when it pays off to wait for the solar roof.
Internet down? No problem. Edge S keeps regulating autonomously: sessions continue, load management stays active, nothing is lost.
Connecting to a central platform – yours or ours – is optional and can be added at any time, for example for multi-site monitoring or billing.
12–24 V DC, −20…+60 °C, fanless, 2× Ethernet, RS485 and CAN: Edge S sits next to breakers and meters – no server room, no fan.
Honest positioning
Edge S detects anomalies and forecasts loads – but local AI fault diagnostics (RAG over OCPP logs), auto-tuning of charging profiles and the local operator portal remain reserved for Edge L. Configuration happens through the cloud interface or, in reduced form, locally. And if your site grows: your configuration moves to a larger Edge variant via backup – same software base, no fresh start.

FAQ
Yes. Dynamic load management continuously distributes the available power budget across all active charge points – 10 × 22 kW never need to draw full power at the same time. Edge S measures the rest of your site load and uses your grid connection to the full, without ever overloading it.
Your configuration and data move to a larger Edge variant – such as Edge L – via backup. Same software base, same operation: the migration is an afternoon, not a project.
No. Edge S is installed like any standard industrial device: mount it on the DIN rail, connect 24 V DC and the network. The first-boot wizard handles the rest – network, meters and wallbox discovery in under 30 minutes, no Linux skills required.
