Use this battery calculator to convert Ampere hour to Kilowatt hour etc.
You can only change the RED cells.
Discharge Formulas;
Discharge time is basically the Ah rating divided by the current.
Charge Formulas;
Example: Battery Ah x Battery Voltage ÷ Applied load.
So, for a 110Ah battery with a load that draws 20A you have: #110÷20 =5.5 hours.
The charge time depends on the battery chemistry and the charge current. For NiFe, for example, using Solar this could typically be <65% of the Ah rating for 4~6 hours. Other chemistries, such as LiFe & LiMh batteries will be different.
Say, 1200Ah x 48V÷1000 Watts =12 hrs (with 40% loss at the max = 48x40÷1000 =1.92 hrs).
For sure, the backup may lasts up to 4.8 hrs at 100% efficiency.
#1200mAh is the same as 1.2Ah. 300mA is the same as 0.3A
Wh = Voltage x Ah, where 1kW = 1000W.
"C" Rating is the Battery Charge or Discharge Rate.
