maximum power point voltage Vmp is basically equal to or close to the AC
rectifying voltage. That is, Vmp≈1.414*U line, and the input voltage of the
JNPxH series grid for the three-phase inverter U line is the voltage between
any two lines. For example, for the JNPxH series single panel 30Vmp and
18 panels in series, Vmp=30*18=540V≈1.414*380=537.3V.
If the PHOTOVOLTAIC array configuration is not appropriate, when the
photovoltaic energy and AC energy are simultaneously connected, the
photovoltaic energy utilization rate may be poor.
