Formulas for off grid solar systems

Can someone help me with the formulas for sizing a 24v solar panel system, as I have, (8) 6V AGM 200ah batteries, (4) 230W panels, 60A
Morningstar charge controller, 1000W Samlex inverter. I would like to upgrade my system to accommodate 3000wh.
Formula sizing, panels, charge controller, inverter, and batteries? Had them at one time, however computer crashed, had to format disk.
Would like to thank all in advance!!

Just give us all your money!
Ooops rather give us all your information.
Load 3000wh? Load during the year (winters in northern hemisphere have less sun and often larger loads... then again if you run an AC in the summer time and heat with wood...)
Days of autonomy(how many days of no sun do you want to withstand with out running a generator)
Time of day of your loads?
Will you have an alternation energy source?
Direction of solar array, will it be shaded at any time?
Location, where on the earth are you?
Do you need a larger inverter?
etc...
- Assorted other systems, pieces and to many panels in the closet to not do more projects.
For the battery you want to aim for a 0.1C charge rate, and a 0.25C discharge rate. That combined with the forum rule of thumb reratings:
PV+CC 0.77
Inverter 0.85
Battery 0.8
Gets you pretty much everything you need.

Sorry you don't appreciate my help!
For others, truly all off grid solar installations are different. One size does not fit all. Rules of thumb can get you in a lot of trouble. better to talk out your whole situation....
