12 hours thereabouts. It's literally the amps*voltage. But for normal lead acid it'll be 50% dod so you only go to 1200watt hours.
Depth of discharge lead acid batteries don't like being discharged to below 50%, could get away with maybe once at 30%

That's why I said 12 hours roughly.not as simple as watts to amps, you need to add in (pf) since its 220v here's a link to a calculator to see the amps (that's what you need to know for your battery) and don't run the battery too low.

Lithuim can go to 100%, but they aint cheap
Watts = Volts x Amps
1200watts Devided by volts which is 24(in your case), would give you 50ah of battery drain( thats for an hour usage). You want your battery above 50% unless you have lithuim batteries those you can drain 100%.
24 because there are 2 batteries is this correct ? Or how did you get the 24?
Yep 12v per battery. 8 hours for small appliances. It can do 100watt load for hours 8 and still be above 50%.
I find it easier to work in watt hours. These batteries have 1200Wh, although only 600Wh are usable due to the battery type. Add up the wattage for your devices and divide that in to 600 to give available hours. e.g. you can power 100W for 6 hours, 200W for 3 hours etc
Thanks that makes sense, so really lithium batteries are far better then but I am sure far more expensive
Correct on both fronts. Lithium also have a much higher cycle count (roughly 10 times) so they actually work out cheaper over the lifespan of the batteries, but the initial capital outlay is much more.
