I go over some of the major differences between 24V and 12V systems and talk about what it is realistic to power off of Lithium batteries and a large inverter onboard. We also talk about lot's of FAQ's that are listed below: Why do people care about watts? What fridges and freezers can you run off solar and wind? How much does Air conditioning draw, and can we run it off our solar? Do we power our laptops with a DC to DC converter or via the inverter? Is it possible to maintain a 48V battery bank? Is a 24V DC system practical? What are the benefits of a 24VDC system? Solar arch- Why don’t we have our dinghy on davits off the solar arch? What is the make and model of our inverter? Could we incorporate water collection into our solar panels. Is there a difference in the taste of desalinated water? Have we ever had issued with the solar panels in high wind? Are the lithium batteries physically the same size as lead batteries? What about safety with Lithium batteries?
