I found this interesting bit of info . Based on the advice of several here and resellers I purchased a Growatt SC 4880-mpv 250 VOC scc. From What I have been told (Ian at Watts247) this scc is the same SCC that is in the Growatt 12kw 250 vdc inverter AIO.
But oddly, these detailed specs are not in the manuel, and no one ever mentioned all the specs an limitations I found in the SCC manual that was in the box.
Notice the specs of the 150 VOC units on the left and the specs of the corresponding 250 VOC units are on the right especially things like operating voltage dc. This might have been what happened to your built in SCCs
