Can i use a 3 phase meter with 1 phase inverter

Some electrical installations in South Africa are 3 phase 400V. The client still wants to keep his 3 phase power and only wants to install a single phase solar system on 1 phase for his critical loads. he will move all his critical loads to that particular phase.

Will the system not get confused if I install a 3 phase meter but use a single phase inverter?

So basically the 3 phase meter would there to see what all the 3 phases consume however only 1 phase will be able to feedback to non essential loads (ESS self consumption), as he cant do phase compensation or feedback into the grid.

Yes, you can. It is ideal to use it on L1. I'm in the same situation: I have a 3 phase grid, but the PV system is a single phase. What I did in addition, was to install between the grid and the PV system, a phase selector, so I always use the phase that is in the parameters.
