What is the starting peak of Midea's 2 kW water heater?

The power of Midea electric water heater is generally 3000/2500KW/H/h, and different models are different. For example, the beautiful F50- 15A4. Rated power:1500w. Midea F60-2 1WB 1, which is the rated voltage: 220V/50Hz. Midea F06- 12A(X) This is an electric water heater with rated power: 1200W and rated pressure: 0.8Mpa and 2kW.. Theoretically, the instantaneous voltage should not change after power-on. If the line capacity is insufficient, the voltage will drop. This voltage drop is not instantaneous, but further decreases with the increase of line temperature.
