ensure that the maximum power point voltage VMP of the photovoltaic array is
basically equal to or close to the AC rectifier voltage. That is, VMP ≈1.414*U
line, the input voltage of JNPXL series grid is single-phase input inverter U line
is single-phase AC voltage, for example, for JNPXL series single panel 30VMP,
11 in series, VMP =30*11=330V≈1.414*220=311.08V. If the configuration of the
photovoltaic array is not appropriate, the photovoltaic energy utilization rate
may be poor when the photovoltaic energy and AC energy are connected
simultaneously.
