[Multiple MPPT Inverter Issues]

Is there some setting that I have missed? is it some bug with my version? ...is worth sending youy the project files (not posting them) or getting the software reloaded?

[3D subfields issue]

I have version 6.07

In the Module Layout page. I am getting issues with the 3D sub fields . In my 3D construction I have 18 seperate rectangular array fields set up. When I go the Module Layout page it does not have all the 3D subfields. It has 18 fields but three are repeats of existing fields and three are missing. I have tried renaming, reloading , deleting and reentering...nothing works...I just get variations on the same problem

PVsyst seems very buggy....or is it just me?

[Multiple MPPT Inverter Issues]

I am using version 6.07.

I have added a couple of images to help clarify my problem. They show the basic array layout with south-east and north-west orientationsand also system sizing screen. I have tried hetro and single axis options. I accept it may be a user error but I have tried a number of options and the only thing that worked was converting the inverter to a single MPPT version

The STP 17000 inverter is 2 MPPT's but the new 20000 vesrions is just one MPPT.

[Multiple MPPT Inverter Issues]

I did find a work around. I just converted the STP to a single MPPT inverter. In fact during the process I found another bug, I tswapped to a newer STP 20000 from the older STP 17000, because according to the SMA website it has only a single MPPT, but in PVsyst it has it marked down as a 2 MPPT inverter. Unless I am mistakne this should be changed.

[Multiple MPPT Inverter Issues]

I am designing a 300kW PV system using upto 20 SMA STP inverters. When I enter the the inverters in the System page I find that PVsyst calculates the number of inverters to be be between about 0.6-1.6 depending on what number of MPPT's I select. No matter what I do I cant get it to accept that I need multiple STP inverters. However if I chose another inverter type such as a SMA SMC whihc has only a single MPPT it works fine. Is this a bug with multiple MPPT inverters or am I doing something wrong (is there some setting I need to change). If so what?

[How do you design a multiple inverter system withtwo orientations]

I am designing a roof mounted 300kW system with multiple roof surfaces and using multiple inverters (SMA STP's). Each roof element is essentially a gable design and all of the modules will be in one of the two orientations (exactly 180 degrees oppposite). Do I have to model it as two separate fixed tilt systems and then just add the result manually or can I use PVsyst to create a combined design. I tried the hetrogenous dual orientation option but couldnt get it to work. Your assistance would be welcome.
