[QUOTE="condor22, post: 119053, member: 1932"] Last test for a while, I ran my 100AH van battery down to 73% full (27amps used) My 110W concertina folding panel was deployed on the van roof for 7 hours and the battery is full. So from this, approx. 25% used, which is optimum for battery cycle life, needs 1 x 110W or 120W to fully charge on a sunny day. I can't test for winter conditions for a while obviously. Re my use, my TV draws 2.5A @ 12V, a couple of LED lights draw about 0.5A, the water pump would get no more than 15 minutes of use so about 1.5AH. If I go detecting after breakfast, my van is using no power, so I get home in the arvo, maybe use the TV for 5 hrs and the lights for 6 hrs - 12.5+3+1.5 = 17AH. My next test is to use the inverter to charge my GPX battery, but to get to 25% use I have 8AH to spare. I use no power when asleep. The logical progression is that if you need between 25AH and 50AH then you need 200AH of battery and 220 to 240W of solar, easy....... [/QUOTE]
