The video below explains the two most important solar sizing equations you need to know when shopping for ANY solar generator / off-grid (battery based) solar kit. Once you understand these two solar sizing equations, you will know how to choose the best solar generator for your needs.
The 2 most common off-grid solar questions we get asked are:
#1. How long will it take to recharge this solar generator from the sun?
#2. How long will this solar generator last me?
The video explains the exact calculations you need to know in order to figure out the answers to the two questions above. (Keep in mind the same logic applies to bigger off-grid battery banks as well).
Again, to recap the video, these two off-grid solar sizing equations are:
#1. Battery Recharge Rate (From Panels or Outlet) = Battery size in watt hours / Total wattage input
#2. Battery Bank Usage Time or "Run Time" = Battery size in watt hours / Load size in watts
