Hi. I have a problem with a SMA STP10000TL-10 with only MPPT 1 connected really (2*22 panels 235W). I obtain a error at each trial : If i create only one subsystem with this inverter (main input 2*22), i have an error, i must to define the second MPPT. If i create two subsystem (main input 2*22), it's impossible to define 0 to secondary MPPT. If i create two substem (main input 1*22 & secondary input 1*22), the inverter is marked as highly undersized. I don't understand this particular case ?!! Could you explain to me for resolving? Thanks !!!!!
