CENTRAL INVERTER CONFUGARATION

[Ranjit]

I AM WORKING ON MW SCALE PROJECT IN WHICH WE ARE USING 4.4 MW INVERTER WITH 4 MPPT WITH 32 DC INPUTS PER INVERTER(8 NOS). I WANT TO PREPARE THE SYSTEM FOR AROUND 50.215 KVA SYS WITH 90910 PANELS OF 550. SO HOW TO GIVE VALUES OF SCB VALUES IN PVSYST SYSTEM PAGE?

Dear Ranjit,

 

Can you tell me where in PVsyst you are blocked so I can help you?

Otherwise, I invite you to watch our tutorial to understand how to create a project in PVsyst.

 

You didn't mention the inverter brand or the PV module brand you want to use.

THANK YOU, SIR, MY DOUBT IS MENTIONED BELOW

INVERTER BRAND IN SINENG AND MODULE IS SOVA SOLAR

IN OUR SYSTEM WE ARE GIVING INPUTS TO INVERTER WITH SCB. BUT IN PVSYST I NEVER USED SCB AS TILL NOW I HAVE WORKED ONLY ON STRING INVERTER. 

HOW CAN WE DO STRINGING FOR THIS CONDITION.

Dear Ranjit,

 

If your connection is consistent between each string, there's no need to mention the SCB. However, if there are differences between strings, you should specify this using sub-array and MPPT features.

Can you tell me what your string configuration is?

SURE SIR 

I HAVE ATTACHED THE IMAGE FOR MY PROJECT STRING CONFUGARATIONS. ALSO, I AM ATACHING THE PVSYST INTERFACE SO THAT YOU CAN UNDERSTAND THE ISSUE I AM FACING.

Dear Ranjit,

First, click here in the higlighted in orange: 

Then you will have 2 subarrays. 

 

1. In the first subarray,
   1. enter "Nb. of inverters": 6,
   2. then in "Mod. in series" enter: 22,
   3. and in "Nb. strings" calculate: 6 (inverters) * 21 (strings) * 25 (SCB) = 3150.
       
2. After that, in the second subarray,
   1. enter "Nb. of inverters": 2,
   2. then in "Mod. in series" enter: 22,
   3. and in "Nb. strings" calculate: 6 (inverters) * 20 (strings) * 25 (SCB) = 3000.

We don't define the SCB in PVsyst. If you follow these steps, you will be able to simulate your project.

Thank you very much for your help, sir.
