2 quattros in parallel split phase, can I add a third quattro as charge only?

I have two quattros set up in split phase on my boat. My lithium bank can take much more charging than the quattros can provide. Is it possible to add a third quattro to function as just a charger? I know that for full split phase setup i'd need four quattros, but I dont need that much inversion, just an increase in charge power.


The battery system is hooked to a cerbo and everything runs over dvcc.


The boat goes long distances and redundancy is very important. Having a spare quattro sitting there in the event one of the primary inverters has an issue is very appealing.


This is as opposed to hooking up a skylla-i via ve.direct.
