Remote firmware update

Hi, I did a successfull remote firmware update on a Multiplus II 48/5000. System has Cerbo gx, 2 x smart solar mppt 250/70 and 2 x Revov R9 11.2kwh batteries. After the update the mppt's show no Solar and not charging. Nothing changed on site. Is their something I can do remotely? Everthing was working before the update and no load was connected. The system has a changeover to grid only, so the internet connection stayed on.

Are there fuses between the MPPTs and battery? Does the MPPT show battery voltage when accessing it in Victronconnect? In the VRM devicelist, delete the MPPTs so it can be reinstated and ensure all firmwares are up to date. Also worth checking that the settings are correct on the multi. PS - I you may already have done this, but you never know.

Did you converted, adjusted and uploaded the settings of the MultiPlus?

Hi, I followed the instructions on Vrm, possible I made a mistake. Can I give you private access to check it out? How do we get in contact?
