Fresh Questions, Practical Answers: PVsyst Q&A Series #5

The PVsyst version used for the following Q&A is 6.66 or higher, but other lower versions can also be referenced for guidance. 1. Can the power factor of the inverter in PVsyst be adjusted? [Teacher Chen]: By default, the power factor in the inverter parameters is set to No settings, but you can open the inverter parameters and set it within the range of 0.8 leading to 0.8 lagging in the "Power Factor" option, as shown in the interface in Figure 1. ▲Figure 1: Power Factor Adjustment in the Inverter Parameter Interface 2. How to set up a system with 39 PV modules? Should there be 2 sub-arrays? One with 20 modules and one with 19 modules? [Teacher Chen]: As indicated in the title, this photovoltaic system utilizes a total of 39 modules and shares a single 10kW string inverter, where the MPPT input channels of the inverter are 2…
