have ordered my first one this will enable me to fit the 48v hybrid inverter i bought 3-4 weeks ago , also bought a basic 100a shunt to keep an eye on the battery , will add more batt packs as funds permit

Generally it is preferable to use 48v batteries as opposed to 4x 12v in series because in that arrangement you have 4x as many BMS's and wire connections to fail. Technically you should also use a battery 'equalizer' which keeps the 4 series batteries in balance with each other, which adds minor cost (~$60) but another whole set of wiring connections and electronics to potentially fail.

I have some of each. I have 4x 12v 280ah in series, and 4x those 48v 50ah batteries in parallel. Neither has given me issues so far. But moving forward i will be adding only 48v batteries to the system, not adding any more series strings of 4x 12v. The only reason i initially did that was because it was the cheapest option at the time. 13kwh for $2400 (last summer).

Cheapest now is probably ecoworthy 12V 280Ah for $520 each, 14kWh for $2080.

got one delivered now i could do with some info , am i right in saying 12 cells at 4,2v =50.4, so why does it have 51.2 on the box and on the little card specification guide it has operating voltage 40v-58.4v , i dont want to set up the max charge too high so untill i understand the batt pack i will leave well alone ,
