OCPP Connect
A resilient OCPP backend for mixed hardware fleets
Connect and control chargers from multiple vendors and OCPP versions through a single, hardened backend and one clean API.
OCPP Connect
One backend for every charger you run
Running mixed hardware across sites and countries means juggling different OCPP versions, firmware quirks and network conditions. AmpNexus abstracts that complexity so you onboard chargers faster, keep sessions stable and expose one consistent API to the rest of your stack.
Multi-version support
Run OCPP 1.6 through 2.1 side-by-side on one backend — modernise hardware on your schedule, not with a big-bang migration.
Resilient event handling
Handle out-of-order messages, intermittent connectivity and retries without losing session data or commands.
Live status
Connector availability and health in real time, streamed to your systems via webhooks or SSE.
Smart automation
Detect issues early and improve uptime with automation hooks into the rules engine.
Full event history
Boot, Status, Heartbeat, MeterValues and diagnostics retained for audit and root-cause analysis.
Future-ready
Built to evolve with new standards and compliance requirements as the protocol landscape moves.
