or 6 x 600 = 3.6kwatts. across 24 hours since he is charge batteries he can run 24 hours if he uses

Phill, I would like to add a few corrections.

12*100 = 1200w*2 = 2400w is the max energy he can store in those two batteries.

Also, the 100Ah label on many batteries could be misleading, it depends on the manufacturer (you need to reach the sheets), if it says 100Ah C100 it means it's only capable of providing 100Ah if discharged over a period of 100 hours, so a 100ah C100 battery could very well be just 80Ah C10.

Also, most batteries will have the highest number of cycles when the depth of discharge doesn't go past 50%, going 100% on the battery will probably kill it in a few hundred cycles, I think for the average battery you find the market if you go near 100% DoD you will hardly get 300-400 cycles on the battery which means for daily use, every year he will need to get a new set of batteries.

To keep this pretty simple, if you want to achieve max economic gain from the setup, you need to account for the following:

1- 20% power loss from the DC<>AC conversion (which means the total power you can store is 2,400w a day (hopefully will get your two batteries fully charged)
2- Use no more than 50-60% of the battery capacity to get a good number of cycles, so anywhere between 50-60Wh

If you need to use a miner that needs more than 50-60W, you are going to need to increase the size of your charger (be it a solar pannel or wind turbine or whatever) and the size of your batteries.

Note I left out battery draining to zero. Above

so I will correct what his 600 watt panel could do.

@mikewith Not exactly what you or I said , but here goes a longer explanation. Most of the world averages 5-6 hours full sun. WTF am I talking about?

Sunrise 6am your charge rate sucks. 9am or 10 am your charge rate gets better.

12 noon it peaks.

2 or 3 pm it drops

you sunset at 6pm so right before that it sucks.

So even though it was 12 hours of sun most of the world average 5-6 hours of 12 noon full sun.

That is how I got my 5 or 6 factor.

so 600 watt panel x 5 = 3000 watts of charge

or 600 watt panel x 6 = 3600 watts of charge

this counts charging losses.

Now for doing ac to dc some invertors are really good they do 95% even 96% but they cost $$$

shitty invertors do 85%

so a 600 watt panel at best is 3600 x .95 = 3420 watts

at worst it is 3000 x .85 = 2550 watts

now do 2550/24 = 106 watts constant draw

3420/24 = 142 watts constant draw.

and as you said this will be very hard on his battery since drawing down to 0 fucks a battery up.

So he could run 19 hours a day to save his battery

and do between 106 and 142 watts.

at best he can do a few usb sticks and a rasp pi with his setup
