Hi all. I recently updated my 220V/5KW Quattros to firmware v504 and my 150/45-TR MPPTs to v1.61. I'm having an issue where the CCGX doesn't recognise the MPPTs at all but then suddenly does and they come into the display. Based on this I suspect a comms issue, which I'm investigating. In addition, several times a day I get an Error 25 - incompatible firmware fault. Is there actually any incompatibility or is this likely connected to the possible comms issue?
UPDATE/EDIT: closing this question since it has morphed into a "why is my display not reading the swu file" type question so I'll raise a new one.
