    Why does a string inverter have a 230V output?

    The reason for this starts from the principle of the power inverter. For the DC-DC-BOOST circuit of the string inverter, the DC voltage needs to be boosted and stabilized to a certain value (this is called the DC bus voltage) before it can be converted to AC power. As to the 230V output, its DC bus voltage should be about 360V.

    What is AC transient low voltage & transient overvoltage?

    During the fault and its recovery, AC transient low voltage and transient overvoltage (TOV) will occur in the sending‐end system.
