Hi I have just updated the firmware on my 48-5000 multiplus 2 as directed, now I can’t get any output from ac2 and can’t use half of my appliances, is there any way to revert back to the old firmware
How did you updated the device?
Did you follow the instructions step by step?
An update resets all settings.
I used the victron app on my phone
It’s just tha ac2 not working atm
Did you backup your settings before the update?
Without any special programming the AC Out 2 is only active if AC IN is connected.
Ah that may be the issue, unfortunately I didn’t backup , lesson learnt, is there anyway to program the unit I have the mk3 and the laptop
