With regarding your weather why not invest in a serge protector unit and also a small backup unit that has power for x amount of time alarms if their has been a power serge or brake and instantly switches to backup power unit or so. Or just have a good serge protector unit if wanting to keep running.
Uninterruptible power supplies for miners would be horribly cost prohibitive for the minimal protection they provide.
YOu can get some good units that will power for 10 hours generating 1400w but would need a fair wack of them if using a lot of units probs out weigh and never brake even on cost for them
