Useful with a grid inverter?

I had checked with the LANX manufacturer if I could connect this kWh meter to a grid connected micro-inverter but they have not responded to my email, so I have not tried to use this yet. The technical aspect is that the inverter checks for 240V before syncing with the grid and I am not sure if 240V will be present on the inverter side of the kWh meter. If not then the inverter may not start up.
