I thought I'd share a pic of one off grid system I helped build this summer.
This is 3kw of solar and 18kw of Volt based lithium with SW Schneider inverter and 600/85 solar controller. I call it the sweetheart.
This fella is running his large cottage; Electric hot water etc and charging his electric car (Leaf), off of solar. I know. Volt batteries. And a Leaf car. Kind of funny.
It really is about load management and smarter building. His cottage is well insulated. Takes advantage of a hillside for earth tempering of hot and cold weather. Yet in most other respects it is similar to a normal tract home.
