inverter/charger + additonal charger recommendation

Hello!

For my mobile install, I have the cells to assemble 608Ah of 24V battery storage. (2 x 304Ah 24V in parallel). The recommended charge and discharge rate is .5C. I believe the maximum charge rate of the 24V multiplus ii 2 x 120 is 70A. 70A seems pretty far from the 300A I could be charging at. Is there another Victron charger I could use in parallel with the multiplus? Using 2 multiplusses seems a waste because I wouldn't need the additional inverter.


(My reasoning for using 2 x 24V instead of a single 48V was to have some redundancy, in case there was an issue with one of the BMSes. I realize that if I constructed a 304ah 48V battery, the 48V multiplus would effectively double my charge rate and get me half way to .5C.)

What will your charger be powered by? AC/Alternator?

Thanks @kevgermany , I didn't see this comment section earlier. It's powered by AC.

More specifically, 110VAC and possibly 220VAC 60hz

Any of the AC chargers can work this way. The IPxx chargers are waterproof, depending on the rating. Not too bulky.
