800
Wallboxes on one instance
One operator runs 800 wallboxes through a single Edge V instance – routing, load management and monitoring on one device inside their own infrastructure.
NeLeSo Edge · Appliance family
The OCPP server that lives on your site.
OCPP server, load management and monitoring as a ready-to-run device on site – from the low-cost LTE entry box to an AI appliance. Offline-first, vendor-independent, with full data sovereignty. Field-proven: from 8 charge points at a campsite to 800 wallboxes on a single instance.
Four variants
One software base. Four form factors.
All variants share the same proven software stack – you simply choose where it runs: in the low-cost LTE entry box, on your own virtualization, on the DIN rail or on an AI appliance.
Edge Go · Entry box
The low-cost entry – without AI.
Compact gateway box with built-in LTE for up to 10 charge points: OCPP server and dynamic load management, offline-first – even where there is no network on site.

From the field · Load management
A 180 kW connection. 180 pitches. 8 chargers. One box.
A real project: a campsite with a 180 kW medium-voltage grid connection and 60 kW of peak PV power. The NeLeSo Edge box measures the live load of pitches and restaurant and gives the charge points exactly the budget the site can spare, second by second – more at noon with PV surplus, less during the evening restaurant peak, the most at night.
- A dynamic budget instead of a rigid reserve – no grid upgrade needed
- PV surplus flows into the vehicles first
- If the connection drops, the box keeps balancing on its own
Proven at scale
In production – not in a datasheet lab.
up to 1,000 kW
Hyperchargers on one device
30 high-power chargers with up to 1,000 kW each run through a single NeLeSo Edge instance at one customer – power classes where mistakes get seriously expensive.
Campsite
Site-wide load management
A 180 kW grid connection, 60 kW of PV, 180 camper pitches and 8 dedicated charging stations – balanced by one Edge box in the control cabinet.
Delivery & operations
Unbox, connect, charge.
Pre-configured Every device leaves our test lab with a 24-hour burn-in, serial number and your base configuration.
First-boot wizard Network, meters and wallbox discovery in under 30 minutes – no Linux skills required.
Signed updates A/B updates with automatic rollback; you decide the maintenance windows.
Support that follows through Remote diagnostics via opt-in tunnel, device replacement with automatic configuration hand-over.
FAQ
Frequently asked questions about NeLeSo Edge.
Do I still need a cloud?
No. Every Edge variant works offline-first and fully autonomously. Connecting it to a central platform (yours or ours) is optional and can be added at any time – for multi-site monitoring or billing.
Which wallboxes are supported?
Any charge point speaking OCPP 1.6J or OCPP 2.0.1 – vendor-independent. Meters and energy measurement via Modbus RTU/TCP, SunSpec and EEBUS.
What happens if the hardware fails?
Basic support: replacement after you send the unit in. Support Plus: a pre-configured replacement unit shipped in advance (advance replacement). Your configuration is backed up automatically in encrypted form and restored onto the replacement device.
How do updates reach the device?
Through signed update bundles with an A/B scheme: installed on the inactive partition, live only after a successful self-test, automatic rollback if anything fails. You decide the maintenance windows.
Can I start with Edge S and grow later?
Yes. Configuration and data move to the larger variant via backup – same software base, so the migration is an afternoon, not a project.
