Modular inverter how to

[Nikoloz]

Hello

I have such question. does anybody had used modular inverters ? Sungrow_SG1100UD what about this inverter ? when I uploaded OND file in PVsyst  there is no information about MPPTs, there is some error with dtasheet ?  I have to make desighn of 100MW plant but how to organise strings in mppts?? 

here is datasheet link https://en.sungrowpower.com/productDetail/4102/1-x-modular-inverter-sg1100ud-20

Dear Nikoloz,

It seems that the inverter you want to use is a central inverter with only one MPPT. This means all strings connected to it must be identical.

So, you don’t need to worry about the MPPT definition. In PVsyst, just select the configuration “PNom sharing within the inverter” (see below).

Then, you only need to specify the number of inverters.

The 1100UD is one inverter module that is typically installed with other modules in a single PCS, like the 4400UD-MV. You will have four mppts with the 4400, each 1100 is one mppt as stated above.
