Before looking at a single-phase meter, it is important for you to first understand what a phrase means when dealing with electricity. For this reason, a phase in electricity is the voltage or current on a live cable and also a neutral cable.

The instantaneous voltage signal of a phase can be drawn on a graph by use of an oscilloscope. A phase in an electrical circuit will depend on the distribution of the load that corresponds to the unit type. For this reason, different types of phases exist today.
The most common type of phase used mostly in load distribution is the single-phase power. In a single-phase power, also referred to as 1-phase, only two wires are required to distribute the power. This makes them have less power as compared to three-phase power.
From there, we can now define what single-phase power means when it comes to electrical distribution. It is a type of phase that uses a neutral and a phase cable to distribute Ac power to the circuit. The phase cable carries the load whereas the neutral cable completes the circuit for the return of current.

It is sometimes called a residential voltage as it is the type of phase used in most homes. The most common voltage distributed by a single-phase meter is always 230V with an approximate frequency of about 50Hz.
When distributing the single-phase power to a circuit you will need to have a single-phase meter. A sing phase meter also referred to as credit meters, KWh meters, or check meters are electrical meters designed for use in measuring the power consumption in a single-phase power supply. These meters, however, only deal with Alternating current (AC power) supply and not the Direct current (DC) power.
Short answer - No. Unless you consumption and generation is exactly balanced across all three phases, then a single phase meter cannot accurately measure power and energy. That said, did you install a three phase or single phase PV System? If the smart meter is measuring only generation and the PV System is single phase, then that would make sense. You would still need a three phase meter to measure consumption and/or net.
