What limits this battery is its rather than its 50 Ah: 50 A continuous and 100 A for 30 s. Behind a 24 V inverter that is at most 910 W of steady load before the 15 % margin is gone, because the inverter draws its power divided by 25.2 V and by an efficiency we cap at 85 %.
A 2000 W inverter pulls 93.4 A, so it needs 3 of these in parallel; one 1.28 kWh bank of them stores 1,280 Wh usable at 100 % depth of discharge.
On its own it holds a weekend van (400 Wh a day) load for 3.2 days and the year-round van profile (895 Wh) for 1.4 days, with no sun at all. Its 25 A charge limit also caps the solar side: one battery accepts about 720 W of panels behind an at 28.8 V charging voltage, so a bigger array needs a second battery or a controller set to limit current. Without a heater it stops accepting charge below −3.9 °C, which the checker flags for any location whose design low is colder.

How this page was computed
Inverter DC draw = watts ÷ (25.2 V under load × 0.85). A pairing passes when that draw stays at or below 85 % of the combined BMS continuous rating and the surge draw stays under the BMS peak.
