My solar battery backup failed during the big freeze in Dallas last week

I was counting on it to keep my heat pump running, but the inverter fried when the grid went down. Has anyone found a reliable setup for extreme cold?

Yeah, same thing happened to my neighbor. His inverter couldn't handle the cold surge when the power dropped. In my experience, you really need a system rated for the low temps, not just the advertised capacity. I've heard good things about setups with a separate, insulated battery box and a pure sine wave inverter.

Seems like a lot of fuss over a rare event. Those freezes don't happen every year, so maybe it's not worth the extra cost and hassle.
