I purchased a second Flexboss21 to add to my system. I have everything connected except for the parallel cable until I get the firmware updated to match my first Flexboss21. The new Flexboss21 shows off line no matter what I do. The dongle is connected to the network and I can see it thru the app and web page but the inverter shows offline. I have just a battery, grid power and output power wires connected. I connected solar just to see and it does not have any effect, still offline.
