BTW, Ive chose to go the 12V system as everything runs on 12V or less apart from the Lappy, besides, a have the appropriate inverter for the 12V system, tho the amp draw is more than specified going off 12V. ie, lappy draws 3.4A @ 19V, so is approx drawing twice that off 12V?
That being said, I have ran the Lappy out at the Obs for 4 nights with the existing 12V bank of only 180Ahrs, and only a 20W solar panel which charges fully between new moons !
