Frequently asked questions

Customer Proof for EV Charging & BMS Testing FAQ

Are these measured customer outcomes or illustrative examples?

The stories identify their published or anonymised project basis. Any added teaching example is labelled separately and does not claim an additional customer result.

Does a project configuration define every product’s capability?

No. A project describes the delivered configuration and its use. Refer to the current product scope when planning a different setup.
