Using Victron's VM-3P75CT Energy Meter to Measure AC Solar input phase on L2

I'm looking at options for adding a Multiplus 2 based battery system to an existing micro inverter (APSystems, DS3) set up. Manuals show using a three phase meter such as the EM340 can be used to measure grid input on L1 and AC Solar generation on L2, but this configuration isn't shown in the manual for the Victron VM-3P75CT Energy Meter. Despite the higher cost, I see huge benefit in the LAN capabilities of the Victron meter over the other meters, but it's not clear whether this particular capability is available. Can someone clarify please? Thanks all in advance.

Perhaps someone that has this energymeter allready, is able to check if there are options for this meter for single phase , dual mode in the Victronconnect app?

Hi CM. Just wondering if you have installed your meter yet and had a look around the menus?

Currently only either single phase or three phase functions are supported on the latest v1.05 firmware.
