rylan76 Posted March 6, 2023 Share Posted March 6, 2023 (edited) Hi All We have five 3-phase SunSynk 12kw inverters running in parallel. On each inverter's display there is a letter "G" in the left bottom corner. This letter "G" has a circle drawn around it. I've noticed that sometimes the "G" is in a red circle, on all the inverters. Sometimes the "G" is in a green circle, on all the inverters. Sometimes one inverter will have a green circled "G", other times all will have a red circled "G", and all variations in between... some have a green circle, some will have a red circle, around the "G". Sometimes all are uniform (all green or all red circles across all five inverters) sometimes all randomly mixed. See the attachment - surrounded by the red box and pointed to by an arrow drawn on the image. What does this letter "G" in the left bottom corner mean? What does the red circle and green circle that seems to randomly switch between red and green mean? The inverters are working fine, for several months now, whether the circle is red, or green....?! I cannot find any explanation or reference in any SunSynk manual I've managed to find. Any ideas? Thanks Edited March 6, 2023 by rylan76 Quote Link to comment Share on other sites More sharing options...
jgdt Posted March 6, 2023 Share Posted March 6, 2023 I also would like to know. Previously it remained a mystery. rylan76 1 Quote Link to comment Share on other sites More sharing options...
rylan76 Posted March 6, 2023 Author Share Posted March 6, 2023 I have a 8kw SunSynk at home (above five 12kw units are at the workplace) and its circle is ALWAYS green... Something to do with running SunSynk inverters in parallel? Quote Link to comment Share on other sites More sharing options...
jgdt Posted March 6, 2023 Share Posted March 6, 2023 In my case its just a single inverter. Was wondering whether its some kind of auto ground test? This might sound silly and give away my knowledge level, so apologies if this is wacked explanation. Hehe. rylan76 1 Quote Link to comment Share on other sites More sharing options...
rylan76 Posted March 6, 2023 Author Share Posted March 6, 2023 Unknown... the inverters work correctly in my case, whether there is a red or green circle. But I agree, it must mean -something- otherwise it wouldn't be there... I've observed them in detail, cannot find any factor that I can identify that control whether the circle is red, or green. They keep working fine, red or green, doesn't matter. Quote Link to comment Share on other sites More sharing options...
