Grid voltage is higher than PV inverter voltage
According to the principle that the current flow from high voltage to low voltage. When photovoltaic power generation, from the load point of view, the voltage of the grid-connected inverter is always higher than the voltage of the grid, so the load is preferentially used for photovoltaic power generation, only when the power of the photovoltaic is less than the load power, the voltage at the grid point will drop and the grid will supply power to the load.

FAQS about Grid voltage is higher than PV inverter voltage
Can an inverter export electricity to the grid?
For your inverter to export electricity to the grid, the voltage at your inverter must be slightly higher than the voltage at the grid to “push” the excess power to the grid. The higher the amount of electricity you are trying to export, the greater the “voltage rise” between your inverter and the grid will be.
What happens if a solar inverter is too high?
Grid Voltage Rise Is Getting Worse. That's A Problem For Solar Owners If your inverter sees a grid voltage that is too high for too long, Australian Standards mandate it disconnects from the grid. Before the voltage is so high it disconnects, your inverter may also reduce its power output in response to high grid voltages.
How much power does an off grid solar inverter produce?
Take the 15kW off grid solar inverter for example. Its maximum output current is 27.4A. Under the rated voltage of 400V, the maximum output power is27.4*400*1.732=18.98kW, which can satisfy overload by 1.1 folds. When the voltage of the grid is relatively low or around 340V, then the maximum output power of the inverter is 27.4*340*1.732=16kW.
What happens if a PV inverter is connected to a grid?
Grid Connection Some properties of a PV inverter grid connection can cause the grid voltage at the inverter to increase and exceed the permissible operating range if the feed power is high. If this occurs, SMA grid guard, an independent disconnection device integrated into the inverter, will safely disconnect the inverter from the grid.
What is the maximum output power of an inverter?
When the voltage of the grid is relatively low or around 340V, then the maximum output power of the inverter is 27.4*340*1.732=16kW. Under this voltage, no matter how large the module power is, the full-load output is impossible. 2. High grid voltage There are two conditions which might lead to a slightly high grid voltage.
How many volts does a solar inverter produce?
Let's say it produces 10 amperes, and the grid has a resistance of 1 ohm. In this case, the voltage will rise to 220 volts at the inverter. If the solar inverter sees a high grid voltage of let's say 250 volts, it does the same. Only when the grid voltage exceeds some sane limit, will the solar inverter stop production.
