[QUOTE="aogrady, post: 486130, member: 3512"] I updated a link above for running the Danfoss compressor solely on solar, the electronics will handle from 12-45V, perfect for solar. Mine was from here IIRC: http://www.xtremevan.co.uk/product_info.php?products_id=5084" onclick="window.open(this.href);return false; I think i paid about that....was a while back. One thing, most importantly, you NEED thick cable, really, not because it pulls so much current, it doesn't, about 1.2aH, but to minimise voltage drop, the compressor wont start till it has 11.7V, if you cable run from the back to the front is long, which it will be, and you use too thin cable, you wont get 12+V so it won't even start. Once running it has low voltage switch off at 10.4V. So thick cable, i think i posted quite a few links when i fitted mine with calculators to work out cable length versus voltage versus voltage drop. Something like 6mm+ needed, i'm going redo mine when I eventually get around to re-wireing the T Max, the solar set up, and the marine switch bank and battery isolators. I have a length of good 15mm2 cable, more than enough, but can use this as a hub to branch off other stuff.....maybe... :lol: Alistair [/QUOTE]
