Hi All, I have an 8kw Deye inverter. Initially I connect it to 2x Dyness BX51100 batteries, now I added 2x Dyness DL5.0C batteries. Master battery is switched with 3 on and rest off and slaves are all in off position. Inverter to master battery in then out to in of next battery, until the last battery. I used the DTX0400001148 communication cable, that comes with the batteries. If I make the DL5.0C the master followed by the 2x BX51100 then the last DL5.0C, has all the lights flashing (3x are normal) If I make the BX51100 the master followed by another BX51100 and the other 2x DL5.0C's then both DL5.0C's lights start flashing (2 are normal) Do I need to install Dyness LV-Link A – Battery Communication Hub? or can anyone assist in helping me to trouble shoot?
