There are more parallel strings than DC-inputs at the inverter


Recommended Posts


In Solaredge simulations I'm getting a crash during the report generation.

I've noticed that after leaving the 3D simulation, there's a warning -"There are more parallel strings than DC-inputs at the inverter" but, after checking the system, that is not true.

Apart from this, I don't have any other indication about what might be causing the crash.

Hi Luís,

this is an error that was introduced in PV*SOL premium 2023 R4 and will be fixed in the next release R5. The crash may occur when using power optimizers in 1x2 configuration on more than one module area in 3D, for some climate locations. You could try another climate location, or switch back to R3 temporarily, as long as R5 is not released yet.

You can download R3 here:


Best regards,
