What limits this battery is its rather than its 100 Ah: 100 A continuous and 150 A for 3 s. Behind a 48 V inverter that is at most 3,641 W of steady load before the 15 % margin is gone, because the inverter draws its power divided by 50.4 V and by an efficiency we cap at 85 %.
A 2000 W inverter pulls 46.7 A, so it needs 1 of these in parallel; one 5.12 kWh bank of them stores 4,096 Wh usable at 80 % depth of discharge.
On its own it holds a weekend van (400 Wh a day) load for 10.2 days and the year-round van profile (895 Wh) for 4.6 days, with no sun at all. Its 100 A charge limit also caps the solar side: one battery accepts about 5,760 W of panels behind an at 57.6 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 0.0 °C, which the checker flags for any location whose design low is colder.

How this page was computed
Inverter DC draw = watts ÷ (50.4 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.
