We are proud of our Golden SUT Partners, who are collaborating with us for the development of OCTT. SUT stands for System Under Test. A Golden SUT is an OCPP implementation of a Charging Station, Charging Station Software Stack or a Charging Station Management System (CSMS) that helps us to validate OCTT. We have Golden SUT Partners for OCPP 1.6, OCPP 2.0.1 and the development of the OCPP 2.1 in OCTT. Find all are Golden SUT partners listed below!
The benefits of being a Golden SUT Partner
Golden SUT Partners can test their implementations against OCTT and receive targeted, high-value feedback, which helps them to stay ahead and to build strong implementations. Partners collaborating on OCPP 2.1 benefit even more with early access to OCTT for OCPP 2.1, which has not yet been released. We’re proud of this close partnership with our members. Together we innovate, collaborate, and drive change through OCPP.
About OCTT
OCTT, the OCPP compliance test tool, is continuously updated, due to maintenance, bug fixes and new features. Every two months, a new OCTT version is released, that must be validated against a number of systems – or SUT’s.
