 We will need **2,084Wh every day** to run our intended loads.
+==== day/night modeling ====
+You may find it useful to make day/night sections for both AC and DC.  This will yield more accurate numbers if you run many of your loads in daylight instead of at night.  It could save you from oversizing your battery bank.
+Note that very big [[electrical:12v:loads|loads]] may require bigger banks to get the current throughput required.  If you have a 120A load but the lithium is only rated to 100A discharge you will need ≥120Ah capacity regardless how small your actual Wh use is.
