Highest throughput capacity, safest, and most versatile: use Ecoflow's 800W or 500W alternator charger (this option lets you charge & reverse charge, which can be very handy since you don't have to worry about a way to charge the LFP)
Low throughput but easy: XT60i cable for 15A charging, but this will only yield about 200W max into your Delta, and you'll have to figure out another way to charge it
With a Delta 3 Plus (or their other units with 2x 500W inputs), you can make/use a splitter to 2x XT60i, feeding both solar inputs to get about 400W combined (use at least 10 AWG thick wire for this since it'll be pulling 30A continuous)
Medium throughput, more expensive, more capacity: Get two or more same-sized 12V LFPs, wire in series, and feed into solar via XT60i. 2 in series will be around 26V * 15A = ~400W. You could technically do 3, too, for '36v' which would max the 500W solar input.

Would be nice to have a single BMS for all the cells in a 48V bunch though. What's the consensus about ripping out the cells and reforming into larger bunch, not worth it? I've watched a lot of videos on the 48V kits but haven't investigated just using these 12V batteries instead, mostly because I want at least 64kWh and would prefer the cleaner look, but saving ~50% is very appealing.

I have a Delta 2 and want to expand the capacity instead of getting an extra battery from ecoflow.
Thanks!

Other issue is I assume these are limit 1 per account.
Also, if you are considering charging via solar, most solar controllers are current limited. A 30a MPPT can output up to 360W at 12V, but 1,440W at 48V. So you'd need many more multiples of MPPTs.
There's a few other big reasons, but for a large residential system, 48V is the standard for a reason. And 48V native batteries will be a lot simpler down the line than putting 12/24V batteries in series. Don't ask me how I know...
