Thanks for the replies. I am including a part of a reply to my original post: 130-140AH per day is not unreasonable - in fact, I think it is a bit optimistic. If you add another fridge to that and a computer, it will easily go over 200AH. Most people don't realise that. 500W of solar should replace around 150ah per day, so while it is sunny you should be OK. IMHO, 3 x 120AH batteries is nowhere near enough. SO, it would be interesting to know how many Kedron owners struggle with power reserves with a 215L fridge, TV lights etc and the standard 3 x 120 aH batteries and 3-4 x 140 W Kyocera panels. Fine while it is sunny, otherwise out with the gennie or onto 240v. Hopefully will stimulate a few more comments on power usage. Cheers, Ian
