My gut tells me that is OK. Your inverter charger may have been set for AGM batteries.

In my bus I have a single alternator so both the wet cell bus batteries and the AGM house batteries are being charged simultaneously. Based on what I have seen on my voltmeters when running, my voltages are consistent with my understanding of the safe level for AGM. I am presuming that the bus batteries tolerate lower charging voltages.

The charging through your alternators is your other concern.
