Fortunately real work is beginning to lighten up a bit, so I should be able to devote more time to our mining company going forward. I'm in the early planning stages of designing and installing 220/240v infrastructure for our coming Avalons. I survived one year of trade school instruction in industrial electricity so the wiring should be pretty straightforward despite my rustiness.
I have one of these UPS units in mind for our initial infrastructure:

I chose these because they seem to be well built and well received. It's also one of few suitable units sold by bitcoinstore:

That one says weight 222lbs. Wonder why the discrepency. Perhaps it's with/without batteries as these are surely the greatest portion of the weight.
