So.. is that BAD if they spark.. is it yet another thing we DIYers should know how to do.. e.g. pre-charge resistor thingy? Or is that just some knowledge some pick up along the way but it wont affect anything? I am guessing the spark is IN the 48/3000 unit itself.. or is it at the switch.. any danger to worry about?The contacts of the switch will spark when turned on if you haven't used a pre charge resistor to charge the inverter capacitors first.
Multi's/Quatro's will power up from the battery being connected, but they can stay on powered by AC in without it.
So can I lay the unit flat? I have a shelf I want to put it on. I can't mount it on wall or anything. Does it get hot? I have this sort of plastic liner (not sure its plastic but came with my cheap 4 shelf metal 2x4 shelf that I got at Costco for like $60 or so) that covers the "gaps" on each shelf (made of thing metal design). Not sure if I can lay it flat on this.. if it gets really hot on the bottom of the unit, etc?
Long story short, I need to sort of "hide" this from the wife.. she blows up when I spend money (dont ask.. long story) so trying to put this and my rack battery in a location not easily seen. The rack battery I assume is fine since you can put several of them on top of one another. I can wire up some 12v fans if need be to blow across the units if that helps. But basically the 48/3000, distributor, switch, cerbo gx and the 48/24 DC/DC (if I can use it) will be on a shelf and the battery on the shelf below about 1 foot or so apart. Plan on running about 2 feet of wire at most from distributor to battery and so forth.
