Here is a link to download PSCAD case studies with a single-phase PQ inverter model:
And a link to the paper where the model and application are described:
The inverter is modeled in the DQ reference frame with decoupled P & Q control. For your application, you may have to replace the P reference with input from MPPT and Q reference might be determined by a fixed power factor or a given Q setpoint. For the case studies above, the P & Q references are set by predetermined values through a CSV file; to modify how to set these references should not be difficult.
Let me know if you have any questions concerning the PSCAD simulation files
