Hi, With which version of PVsyst ? v6.64 - TRIAL How do you modify/save this component, and which component ? I select a solar charge controller (a MPPT one) from the manufacturers list or the generic one. Then I open its configuration file (a new window pop up). I go to tab thresholds and then modify the SOC trigger OFF and ON. Because I have made some change, PVsyst tell me that I need to save as. So I do it (window pop up close) and select my new custom configuration on the list. what is not correct ? If I start my simulation, the report shows that the battery management control stay at its default value (which is Discharging SOC = 0.20 / 0.45). If I check my custom configuration by open it, I can see that nothing has changed. Everything go back to its default values after saving my config to another file.
