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

[Rich Nicol]

Hello Wrenches

I have a site with two PAE 48v Magnum inverters stacked. System voltage fluctuates ~ +/- 4 volts ranging from 243 to 247. Evenly split on the two lines.

Site has a few electrical peculiarities I haven’t seen on the many other sites I have with Magnum inverters. 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. 

I checked all neutral connections and verified proper N-G bond.

All connections appropriately torqued.

My recollection is the modest voltage swings are within Magnum spec. But its constantly moving about which seems somewhat suspect to me.

Any suggestions?

Thanks

RIch
