Hi John, Are these made in Mexico units? We have had a few issues with quality control since the relocation, not specific issue you have, but charger-related.
There are two settings – Under the Shore menu make sure Amps are set properly, and then there is the battery charge rate in the setup menu. That inverter should give a 63A charge @ 48VDC, and generally doesn’t really care about power quality even with very cheap generators the charge rate is good.

I have noticed on several Magnum Installations that the charge rate is low compared to the inverter rated output. Typically I would assume the charge rate should be up to about 70 to 80 % of the inverter capacity, but I am getting only about 1400 watts (26 amps DC) from it with a 14kw generator. Is there some setting I am missing that would limit it other than the charge %. I know of one system where they added a 2nd Magnum inverter and then had problems with them working together consistently. I have used the 8 kilowatt Radians for any off grid with significant loads and battery capacity and easily get 6000 charging watts from a large generator. I also needed remote control of the generator (Generac EcoGen 15 kw so a quick inexpensive but clunky solution I came up with was to add an old (2003 vintage) used MX-60 to the system purely to use the Aux relay with a used HUB and old but good Mate3. Works perfectly giving us AGS start and stop voltage settings and basic battery voltage graph. I would be interested in other ways to remote control generators with non Outback inverters. FlexNet DC?
