Model evidence at a glance
ABB documents OCPP 1.6J for Terra AC and the Open Charge Alliance lists certified Terra AC variants. Sentinel message coverage and evidence quality remain to be verified by AmpNexus.
Manufacturer documented means public protocol evidence is available. It does not mean the model is onboarded, supported or AmpNexus verified, and it is not electrical safety certification.

Integration paths
OCPP
OCPP 1.6J
Publicly documented protocol capability only; installed firmware, configuration, access and message coverage require integration review.
- Mapping version
- Not recorded
- Last verified
- Not verified
Integration limitations
- A public OCPP statement does not establish which optional profiles, messages, fields or vendor extensions are enabled on an installed unit.
- No AmpNexus model and firmware mapping has been published for this profile yet.
Capability evidence
- Reported, not yet verified
Integration documentation
OCPP 1.6J interface
- Integration source
- abb-terra-ac-wallbox-documented-ocpp
- Availability conditions
- Subject to the documented model, firmware, configuration, credentials and backend access route.
- Units or meaning
- Public protocol support; not an AmpNexus-verified Sentinel capability mapping.
- Freshness or cadence
- Not yet verified by AmpNexus
- Evidence source
- ABB Terra AC OCPP 1.6 implementation overview; Open Charge Alliance — ABB certified products
- Last verified
- Not verified
Protocol compatibility is the start of an integration assessment, not evidence that every Sentinel signal is available.
Evidence boundary
What is not yet evidenced
- Sentinel operational capability and data quality have not yet been verified for the stated model and firmware scope.
- Optional OCPP profiles, message coverage, security configuration and vendor-specific fields remain to be mapped.
- Thermal, contactor, CP/PP and protection evidence must not be inferred from protocol compatibility alone.
How to improve this profile
Expose and verify more evidence
- Connect a representative unit to the AmpNexus integration test path.
- Verify boot, status, transaction, metering, fault and firmware evidence against the applicable firmware.
- Work with the manufacturer to document vendor-specific telemetry and known limitations.
