Voltage on enphase system not populated

I added both my enphase systems today (KB-Oost and KB-West). I managed to aggregate both in KB-OostWest. Thanks to the great documentation and forum, the setup was easy!

One thing remains a puzzle for me: the voltage data is not populated on neither system.
Is this a limitation for the enphase systems?

Enphase API doesn’t provide voltage information, so its not available.

Thanks for confirming!
