December 27, 2025Dec 27 Hi all, first post here, thanks for adding me. I have 9 x Axpert MKS II 5kW clones in parallel, 7 of them (Easun Isolar SM II) running on 71.87 and the other 2 (MKS II 5kW-B) running on 50.01 and 50.02. I have tried to update 50.XX to the 71.XX but getting "can't open COM port " error. Is there an intermediate F/W or Inverters with 50.XX running their own version of F/W which can't be upgraded? Attached are the 3 different inverter models on the same system, any thoughts? Thank youEdit: I have noticed 50.01 and 50.02 is only listed for Axpert King II inverters, but mine are MKS II... Attached pics of the displays as well. Edited December 27, 2025Dec 27 by andrey123456 more info
