<p>HI Lee. I am an Electrical Engineer and TAFE teacher. I teach Renewable Energy. I terms of your question, you need to do as accurate estimate as possible of what your average daily energy consumption will be for each month of the year. When you say off-grid for 7 -10 days at a time, are you talking about a property that has grid power some of the time ? or totally off-grid ? Perhaps you mean no solar for 7 - 10 days at a time.</p><p> </p><p>Cheers</p><p>Garry</p>
