Battery charging with 2 sources at once

[GPAY]

I have the battery isolater in my Hawk that allows my 100 amp hour agm battery to be charged when the truck engine is on. I also have a 100 watt Renogy solar panel with 30 amp Wanderer controller. Is it harmful for both to be on at the same time or should I use one or the other?
Thank you

Not harmful. I've got 330W of solar and the ability to charge via the alternator too. Not unusual to see 600+W of charge going into the batteries.

The battery does not care where it gets its recharging from even if more than one source as long as the charge controllers between the battery and each source are preventing the battery from being overcharged.
