Can i connect a single phase inverter into a 3 phase power meter ?

[Second Energy]

Hi i am currently working on a 5KwP on grid project and ill be using a single phase inverter but the house meter is a 3 phase meter so is it possible to connect the inverter to the meter and what consequences will that have on the power output

Sorry for my English

Your English is fine.
Since the 3-phase meter is already able to handle unbalanced loads across the three phases, there should not be any issue with making the GTI feed single-phase only.
You must make sure that the GTI output does not exceed the power rating of a single phase.
Some utilities, particularly for commercial accounts, may be unhappy with too large an imbalance among phases.

Yes if it is a Wye Service. No if Delta

Yes if it is a Wye Service. No if Delta

Expanding on that:

If the inverter requires a neutral connection and a single phase connection, then it can only be connected to a three phase service that also has a neutral (namely wye connected).
If the inverter produces a single phase output but can be connected between two phase lines, then the inverter can be connected to either a delta or wye service.
For the first case (an unlikely one, but certainly possible) you will have to place a transformer between the inverter and the service.

Thanks a lot for the feedback really appreciate it.
