Hi folks,

I am converting a Catalina 34 with a thunderstruck 12kw 48v kit.
Currently have
4 x 48v 100ah batteries 20kw.
3kw inverter generator 30amp 110v

Looking for the simplest way of charging these 4 individual batteries. Each will have a bms and anderson connectors.
I will be using a distribution bus bar.
I know some are using mppt chargers. But would it be best to use a multiplus or any other device. I am looking to have the least amount of fail points in the system.

I use a pair of Meanwell HLG-600H-54A chargers for my 10kWh pack (16S LFP).
It tops out at just over 58V, but that's fine.? They draw ~700W each, so four of
those would just use up the 3kW your generator provides (with headroom).

I also just realized that i will need to series the battery packs for 48v 400ah Lifepo4 with one 200amp 16 BMS.

I think you mean parallel (not series).

If you just have the one large 48V battery, any number of those chargers could be used to charge it,
depending on tradeoffs how much other load you want the generator to supply and how much battery
discharge you want to keep up with (or how fast you want to recover battery SOC).

IOW, my suggestion to use four chargers was before I heard about the four 100Ah batteries being paralleled.
Once in parallel, less than four chargers could also work.
