nanuk Posted September 1, 2021 Share Posted September 1, 2021 Hi,Does the PVsyst take into account the inverter euro efficiency in the yield or PR? or does it follow the values interpolated from the figures in the table (Pin(DC) Efficiency [%] and depicted in the graph?

satashi0123 Posted September 2, 2021 Share Posted September 2, 2021 Dear nanuk,In PVsyst there are 4 ways of defining the efficiency of inverters : - from a single efficiency curve eff = f(Input power), specified by up to 8 points - from a single efficiency curve eff = f(Input power), automatically built from the Maximum, EURO or CEC efficiencies and the Power Threshold (Pthresh) - from a set of 3 efficiency curves eff = f(Power, input voltage), all of them specified by up to 8 points - from a set of 3 efficiency curves eff = f(Power, input voltage), all of them automatically built from the Maximum, EURO or CEC efficiencies and Pthresh.Automatic efficiency profiles: this option is used when only the Maximum and EURO or CEC efficiencies efficiencies are available. PVsyst then construct default profilesYou can see the detail here : https://www.pvsyst.com/help/inverter_efficiency.htmSo if you don't check "Builds profile from given efficiencies" it will use the table you see on the right side Link to comment Share on other sites More sharing options...
