That is the figure to divide your evening load into; how long it actually lasts depends on what you switch on, so send us the appliance list and we will work it through against this number rather than quote you an hour count.
The LIO II-4810 works with a 51.2 VDC bank. It charges at up to 100 A (Default 30A), and that current — not the bank's capacity — is what the cabling and the fuse between bank and unit have to be sized for.
Up to 150 A continuous. An inverter pulling more than that on a motor start will trip the pack's protection rather than damage it, so match the inverter to this figure.
