Information
Definition
ENA Connect Direct V2G Stack refers to the broader approved or declared combination of V2G charger, inverter or control system and associated equipment used for connection assessment.
Why it matters
It is important because V2G compliance may depend on the combined system stack, not only the charger hardware itself.

Standards and regulations
ENA EREC G98
ENA EREC G98 is the UK Engineering Recommendation for connecting fully type-tested small-scale generation equipment up to 16 A per phase in parallel with public distribution networks. In EV charging, it can become relevant where equipment includes export-capable generation or storage-related functions.
ENA EREC G99
ENA EREC G99 is the UK Engineering Recommendation for connecting generation equipment and larger power generating facilities in parallel with public distribution networks. It is relevant to export-capable EV charging, V2G, storage and larger schemes that do not fall under G98.
ENA EREC G100
ENA EREC G100 is the UK Engineering Recommendation for customer export and import limitation schemes used to control power flow at a grid connection point. In EV charging it is relevant to load management, constrained connections, V2G export control and maximum import limitation.
