My boss who designs all our systems has had me construct AC work consisting of two SMA 1200TL inverters combined. Meaning, own circuit until the finally meet at the 3 phase meter terminals.
I personally thought this was incorrect and they should be totally independant of each other until the bus bar. This system has developed a grid fault (one inverter down) that I must look at on Monday, but feel the design is to blame and there may be damage to one or both inverters?
Does one inverter "see" the other as the Grid, thus create over voltage for exporting power?
Your thoughts please.
