The principle of Parallel mode working When parallel system works on same phase like 230V, you just need to connect Parallel cable and current sharing cable , then inverters will compete and produce host and slave inverter automatically. What if parallel system works on 3 phases, you need to set 23th option, and set P1,P2,P3 …
