Hello Victron Energy,
After updating my MP II 48/5000/70 to V489, I am facing a frequency issue. I changed it to 60Hz. and save the change, but it still shows 50Hz. on the V.E Configure 3, problem that I did not have with the V487. This frequency issue causes all UPS backups to beep a lot because the frequency is 50Hz. instead of 60Hz. Maybe the V489 came out with a bug.
Please, fix it asap!
Best regards.
Hi again.
We tested it, on the exact same device; and works fine: we checked the output frequency with a DMM: 60Hz. Changing it -> 50Hz measured, changing it again, 60Hz measured.
So no bug, at least not a generic one that affects all situations.
Please check again; and if you can't find it, please post the VEConfigure settings file, so we'll check that.
Also, make sure that its inverting, and not passing through AC from the input (generator or shore) that for some reason changed to 50Hz.
