Hello I am currently having some issues with my SHP too. I have all good across the lights and everything looks like it should work. (HAVE 2 Delta Pros connected to panel) My problem is when I try to use battery power it either errors out saying replace relay, or it turns off that circuit and leaves power off until I return to use grid power. Like most everyone I am waiting on Echoflow to respond. Any ideas on what I could do.
