It's time to really be off grid capable. The big project is the installation of a watermaker. This model is a Spectra Ventura 200T and is a low power consuming model which is best suited for an offgrid application. It consumes 10 amps per hour at 12V and produces around 8-9 gallons of water in that period. 10 ah is within the capability of the existing solar panel which generates 7-10 amps per hour. This full detailed explanation shows the challenges that you can expect when installing your watermaker and is more detailed than other videos on Youtube.
