Error in Simulink model

My simulink file was working but when I add the "PV array" block , the following error has come out:

Cannot generate a reusable function for Subsystem block 'Track_6101/<< Synthesized_Atomic_Subsystem_For_Alg_Loop_1_Task_0 >>'. This subsystem is fed by the Ground block 'Track_6101/PMSG Wind Turbine/Grid-side Converter/Model/Ground' that has a nonscalar output signal. Either replace the Ground block with a Constant block having all zero values or modify the 'Function packaging' setting of the Subsystem block to Inline or Function

I had to check the box of "break algebric loop in internal model" in the advanced tab of the "PV array" block. This is in the help document of the "PV array" bolck.
