NOTE: * Vmp: panel max power point voltage.
The PV charging efficiency is maximized while PV system voltage is close to Best
Vmp.
Maximum PV module numbers in series: Vmpp of PV module * X pcs = Best Vmp
of inverter or Vmp range.
PV module numbers in parallel: max. charging current of inverter / Impp
Total PV module numbers = maximum PV module numbers in series * PV module
numbers in parallel.
The 1000VA inverter as an example to set proper PV modules. After considering
Voc of PV modules not exceeds 50V DC and max. Vmpp of PV module close to 45V
DC or within 30~66V DC, we can choose PV module with below specification:
Maximum

Maximum PV module numbers in series: 1
PV module numbers in parallel: N/A
Total PV module numbers: 1
The 5000VA inverter as an example to set proper PV modules. After considering
Voc of PV modules not exceeds 150V DC and max. Vmpp of PV module close to
60V DC or within 60~145V DC, we can choose PV module with below specification:
