It is cold and raining and dark here. Even in the most expensive to live places on earth, you will suffer under the iron fist of the seasons. There is not much power on the solar panels. My inverter makes an awful scream when the battery voltage goes below 11.4. I am sitting here taking a break from Spanish class listening to the inverter scream. 330AH @ 12V is barely enough 120V (approx 3 hrs) to last 36 hours intermittently or 24 hours continuously when the sun isn’t out. I need to mount the other panels on the sides or make a rooftop slide out layered system for an additional 2x 370W to total 1440W.
