I installed a KODAK MKSIII (OGX5.48A) Inverter.With AC charging selection, I get a AC icon (ONLY) on the led display, not a AC & AC/DC with arrows like the user manual indicates. With solar (PV) input, I do not get ANY indication on the led display. So with other words I can not charge my 3X PYLONTECH 3.5KWH at all. With my old inverter RCT 5KVA/4000W it worked 100%. I took the Kodak back to the place I bought it. The have tested it & change my setting(13- to 51v) and told me it would work now, but I have still the same issue. My batteries are at 64% capacity. I have 8x 405w Canadian solar panels.
