4.4 PV Module Selection
When selecting appropriate PV modules for your system, it is crucial to consider the inverter's specifications to ensure compatibility and optimal performance. Pay close attention to the open circuit voltage (Voc) and maximum power voltage (Vmpp) of your PV modules.
Figure 4.5: PV Module Selection Guidelines and Parameters.
Key considerations for PV module selection:
- The Open Circuit Voltage (Voc) of your PV modules must not exceed the maximum PV array open circuit voltage of the inverter (500VDC).
- The Open Circuit Voltage (Voc) of your PV modules should be higher than the minimum battery voltage.
Refer to the table in Figure 4.5 for detailed parameters for the ISolar SMV IV 5.6KW model.
