Hi, I have a question about the Multi-orientation daily-sharing tool. I’m working with three identical inverters, each with 12 MPPT inputs, and 4 different orientations (one for each direction). I’ve already built all my sub-arrays with the correct number of MPPTs, and the Power Sharing window works fine. Since my inverters are heavily oversized (400 kWp for 250 kVA), I assume that power sharing is a crucial aspect of this design. The Multi-orientation daily-sharing window seems to be exactly what I need, as it allows the inverter to dynamically share power between MPPTs with very different orientations. However, I’ve encountered a problem: in this window, all MPPTs appear to be grouped under a single large inverter, and there doesn't seem to be a way to group MPPTs by inverter, like in the Power Sharing window. Is my understanding correct? Is there really no way to organize MPPTs by individual inverter in this interface? I also tried duplicating the .OND file to create another inverter type, hoping it would help. But now, in the daily sharing window, I only see the MPPTs corresponding to the inverter selected in the system definition (not all MPPTs from the project). Thanks for your help! Best regards,

Hi everybody ! I'm use to work only with the "partitioning" tool in 3D scene (+ the "According to module strings" option) and a colleague ask me why I don't use the "module layout" tool for electric calculation (I never use this one !) So I try the module layout tool and I find some inexplicable difference in result. I have simplify the problem with a very simple simulation : 1 string of 26 modules with 1 azimuth/tilt and an obstacle shading approximatly 1 module everytime (very theoretical problem !). With this case, I expect a very low production because of the entirely part of the string is shaded. Sim 1 : using of "Partition" in Near shadings 3D scene and the "According to module strings" option and 100% electrical losses. 1 rectangle in with and 3 in height because my module is a 3 bypass diod. Sim 2 : using of "Detailed electrical calculation (acc. to module layout)" The module is a Twin half cells (JKM-420N-54HL4R-BDV). Result : PR Sim1= 0.387 and PR Sim2 = 0.797 Module layout seems to not take into account the electrical losses on the whole string. I have an explanation but I'm not sure : does the Twin half cells let the string produce even if a whole part is shadowed ? Thank you for your help ! Br
