Growatt communication problem

Deon Blom
in Inverters

Featured Replies

Earlier this year I have installed 2 Growatt SPF 5000 ES inverters in parallel, as per the installation manual, with 3 Pylontech US 3000C batteries. I have connected everything, especially the communication as per the installation manuals between the inverters and from the inverters to the batteries. From the get go I have experienced problems with the communication as it seems the BMS in the inverters are not controlling the charge which leads to batteries over charging continuously as there is a Fault code 3, which means the batteries are over charging and building up serious heat which is a great concern.

I have tried everything in the manual, not that there is too much on this topic.

I would appreciate any advice on this to get this resolved.

Thank you in advance
