So, if you have 600 Amp hours of stored capacity, you can use 300 Amp hours before needing a re-charge. So that would be 300 Amps for 1 hour, and 3 Amps for 100 hours. It's not quite that simple, but you get the drift.

There is a point where simply buying batteries isn't the answer because of weight and cost. A small inverter generator is quite capable of topping up the batteries with a few hours running.

All of this is simply a guide to how long you can "boondock". Solar power increases that time because the solar will put charge in the batteries too.(Actually that's all the solar does ... charge batteries and contribute to inveter output).

It's not whether a single, or multiple batteries will power an individual item like your laptop, but more a case of how long you can power the items you want to run.
When you say small inverter generator like 1000watt one? There is a sportman brand 1000 Watt Inverter*on sale for 199. Would that be better than my dcv 20r inverter and a 100 watt solar kit?

There really isn't a "better" in this situation. 1000W of generated power is 10X the power of a 100W solar panel working at maximum efficiency, but if the load on your system is less than 100W, then the generator would be superfluous ...

EVery aspect of an electrical system affects all of the others, so you really need to plan the components according to need, and that starts with the load you expect and where, and when you will be using it.
