klerindias Posted January 4, 2013 Share Posted January 4, 2013 Hello,i not giving up and trying with sma stp assymetric inputs.I will show each step, please tell me if i did anything wrong.First i added inputs for each sma stp, input A and input B.Then i tried to make easy setup to use this inputs with different numbers of modules.http://img687.imageshack.us/img687/9405/smastp1000tla4.jpgSo i did two subfields:First subfield with input A with 2 strings 22 modules in series.So we can notice i got somehow 2 inverters not just 1. Did i do good input A setup?http://img138.imageshack.us/img138/8839/smastp1000tlb1.jpgAnd I did second subfield with input B and 1 string 14 modules in serie.And here of course pvsys giving warning that input is too small...http://img12.imageshack.us/img12/1899/smastp1000tlwarning.jpgI can live with it if this gonna work BUT:http://img600.imageshack.us/img600/8475/smastperror.jpgI can not do any simulation!!What i did wrong this time?Here is example from sunny design with same setup.http://img713.imageshack.us/img713/3418/sunnydesignteststpsma.jpgPlease help.

André Mermoud Posted January 6, 2013 Share Posted January 6, 2013 In your first step, you have defined: - 4 inputs (which are just the connections)- No use of MPPT. You should check "Multi-MPPT capability" and then define 3 MPPT inputs here. - Save the inverter under another name. After that you can define a sub-array with 2 MPPT inputs (2 strings) and the second one with one MPPT input, and everything should be OK. Link to comment Share on other sites More sharing options...
klerindias Posted January 11, 2013 Author Share Posted January 11, 2013 HelloI did this way:My problem was that i got 107 modules 240W, and want to use SMA STP 12000TL.I splited inverters like this:Inverter 1:Input A1: 21InputA2: 21InputB: 12Inverter2:Input A1: 21InputA2: 21InputB: 11I made one inverter SMA STP 12000TL A4 with 3 "string inverter" and 3 Multi-MPPTI made second inverter SMA STP 12000TL B1 with 3 "string inverter" and 3 Multi-MPPTI made 3 sub fieldsFirst subfieldI used option "Use multi-MPPT features" and putted 4 string with 21 modules , SMA STP 12000TL A4Second subfieldI used option "Use multi-MPPT features" and putted 1 string with 12 modules , SMA STP 12000TL B1Third subfieldI used option "Use multi-MPPT features" and putted 1 string with 11 modules , SMA STP 12000TL B1So i did same 2 inverters, just different names and then i could make simulation. And only in this case i could run simulation.When i tried to do 2 inevrters with ratio "string inverter/Multi-MPPT capability" 3/3 and 1/1 it didnt allow make me simulationIs it good what i did?

André Mermoud Posted January 26, 2015 Share Posted January 26, 2015 You cannot delete components from PVsyst. You have to use your Windows File explorer for suppressing manualy the concerned files in your data in \MyDocuments\PVsyst6_Data\Components\Inverters\ Link to comment Share on other sites More sharing options...
