I am using a Reliance ProTran2 with a Samlex 4024 and Victron Phoenix 1200/24v and I have flickering led lights with both and no flickering with grid power. voltage is stable. I dont know if it is grounding related with the case ground. When i installed the Phoenix it was going to fault with the bonded neutral, so i moved to neutral floating. output was showing a open ground with a outlet tester, but when connected to the Reliance panel outlets tested correct with ground. Any suggestions?
