[RE-wrenches] Magnum Inverters - Digital Clocks Losing Time?

[Jay]

Hi Rich,

This appears to be a newer thing with magnum. I’ve seen this and it’s been commented previously here on the wrenches. Doesn’t appear to be load or charge related. 

It’s definitely not on the older models. 

Magnum says that this voltage fluctuation is normal operation.

Among those is three digital clocks on appliances that lose ~ 5 min per day consistently. A forth clock which is on a weather station with a transformer where it plugs into a receptacle keeps time and of course the computers do as they are web connected.
