LiPo4 battery selection

Recently I met someone who wants to install a solar system to augment the unreliable grid which frequently is under voltage as well as being subject to frequent blackouts. He is sold on LiPo4 despite my suggestion of using flooded LA, I've offered to help but my experience with LiPo4 is, less than limited. Having read threads of others using these batteries/cells it would appear that prysmatic are the way to go, rather than the so called drop in replacements. Done a fair bit of research and have narrowed it down to a few vendors, the price per Ah/cell is $0.75, so a 100Ah cell would be $75 or fractional divisions thereof , the one which stands out is a 24V nominal 240Ah, including a BMS self contained in an aluminum box, any thoughts or suggestions would be helpful. The charging/inverter hardware will most likely be SMA or Schneider due local availability, the capacity will be carefully calculated according to loads, which I'm reasonably well versed, there are so many options regarding cells and capacity, however the primary focus is the inclusion of a BMS, which makes sense, yes/no? This is a link to a possible vendor, I'm in Thailand so logically its reasonable to purchase semi locally for shipping considerations.
