Hi all, completely new to Solar, 6 months in I've finally got a pylontech us5000 storage battery which I'm informed is compatible with my Sunsynk 3.6kW AC 7kWp, however using the supplied comms cable I'm unable to get the inverter to recognise the battery, (cable is the correct way bms at the battery port) searched the net and found very little information on this combination, tried can ports and rs854 and adding number 1 dip switch on the battery, all combinations, so to prevent fault code on the inverter having to run it as lead acid atm, any help would be much appreciated ??
