I assume your using an inverter. A step down to 12v would be much more efficient. Gave up mining to pos coins and just convert/flip to btc. More rewards, less power, no noise (though that is not a problem for you)

Yeah, I have an inverter, 3.5kw outback. I don't really know much about how to work with DC off the batteries directly, I wonder how much power I'm losing. Maybe I can go directly off the load from my charge controller, that can handle 60a. The step down would need to handle the 1200w load. Don't those cost a couple hundred dollars? Something like this:

Wow, thats interesting. So its 95% eff. What the inverter % eff?I'm dissapointed they dont have a 48vdc to 12vdc with that many amps. largest one i could find was 60amps.

Something like 93% on the inverter. I don't think it's worth it to get the converter with my setup. It will take a long time to mine the sats back. Maybe worth considering when designing a system from scratch though. Probably best just to keep everything 12v in that situation though I suppose.
