Well... I ended up "getting lucky"... charged a car battery at a friend's house, and brought it back to my inverter, and plugged in. It ran "most of the night", and in the morning, I got a little battery airstone going.
That night on the way home from work, I stopped to buy additional batteries and chargers, so I could charge them at my mom's place. Spent about $245 or so online at Home Depot to buy a small generator. So, that should show up in a few days, and I should be all set.
Naturally, after spending about $500 on betteries, chargers, and a generator, and emptying the fridge and freezer... Murphy turned the electricity back on.
I'm returning 2 of the batteries that never got their terminal covers removed, and one of the chargers that was never opened. And, naturally, I'll keep the generator around for "next time".
All said and done, I had just put 3 peppermint shrimp in my tank last week. I still count two, and I found either a dead one or a molting the other day.
Otherwise, no major losses.
