I have simulated the same circuit using Sunpower SPR-305-WHT PV Array(Nser=5,Npar=66 and Voc 324,Vrefinit=273.5) for 100kw. But it gives the error as The sample time 1e-07 of 'single_stage_three_phase_grid/Sum8' at input port 1 is different from the sample time 0.01 of 'single_stage_three_phase_grid/MPPT/ SFunction ' at output port 2. Consider inserting a Rate Transition block between the two ports. Alternatively, you can control the diagnostic action for unspecified rate transitions by changing the option "Multitask (or Single task) rate transition" on the Sample Time Diagnostics pane of the Configuration Parameters dialog box. What could be the reason? I have put the sampling time and simulation parameters as in the video

negative value because the direction of the current sensor connected in the circuit. but it should read 100kw, not 2000. in my simulation it shows correctly. you can share the model at my email if u want to correct it.

Hello can you tell me what is the difference between single and second stage grid solar inverters

[@TechSimulator]

when the available solar voltage is low (say less than 300V), then we cannot connect it to the grid with inverter alone. There first we need to boost the voltage to a level which is more then 700V using any DC DC converter, and then connect to the inveret. such a system is generelly known as double stage grid conected solar inverter.

[@TechSimulator]

when the available solar voltage is high(say more than 700V) then we can directly connect the solar to the grid by using inverter alone. such a system is known as single stage grid connected soalar inverter.

[@adarshgupta2870]

why you are getting about 305 volts when you set the ac output voltage like 400 volts and because of this, the total output power is V*I = 305*200 = 61 kW. this is a very big difference while you are designing the system for 100KW @TechSimulator #TechSimulator please answer.
