Wrenches, We still try to encourage prospective off grid customers to do a full load analysis as an initial step in the system design process. To the point: 1) What is a good watt-hours/day figure to use for a typical, modern, new, carefully chosen, fairly large conventional AC chest freezer, if kept in a heated indoor location? Assume 65 degrees and seldom opened. I will encourage that the freezer be located in a shaded, protected outdoor location, in order to greatly reduce winter energy consumption, but I need a good base figure to work with. The proposed system will most likely be 48Vnom, so a Sundanzer or similar DC freezer is out. 2) Same question for a ceiling fan, for general slow circulation of winter heat. The energystar.gov list gives relative cfm efficiency but not wattages. Is 55W still a good figure to use as a default? I have attached a condensed energystar.gov list for the freezers, but wonder what other off grid Wrenches typically use. Also, I'm not sure that Wrenches posts allow attachments, so this may not appear with my message. Thank you, Allan --
