connecting pv array shows no output

when i connect a pv array block in my model with module data user defined then i found output of module to be nan, but when i click on robust discrete model i got some output but in both the cases my scope is completely blank, a complete white screen shows. why & how this happens.

Hi Jyotiprakash,

This issue occurs because the electrical ports on the "PV Array" block are physical conserving ports, not regular output ports. If you connect them only to a "Voltage Measurement" block without forming a complete electrical circuit (for example, connecting to a battery, load, or grid), the simulation cannot solve the network, and you will see NaN values.

To resolve this, connect the PV Array’s electrical ports as part of a complete circuit with a voltage source or load. For reference, you can look at the following documentation to understand proper PV Array connections:

Hope this helps!
