I am trying to model the power output from a solar array connected to a boost converter. However, my first issue is that the power output from the array itself (V_PV*I_PV) seems to be very low (~0W).

When I run the default model with the 14 modules in parallel, it runs fine. But when I change the number of modules to 5, it outputs almost 0W power. I would expect it to output 1/3 of the original 2200W. But it does not do this.

Could anyone suggest why simply changing the number of modules would have an affect on the model's performance? Thank you.
