After having to deal with three 15-minute refueling generator shutdowns per day from the Isaias blackout, I was thinking about getting a whole-house-sized Eaton 8kVA to hold until we hook up the portable generator. After looking at the price, I started looking at the off-grid inverter options. There are a few out there for under $2K that have 240V outputs and internal logic to switch between multiple inputs like grid, solar, battery, and generator. This will probably be what I do, since the price should be more than half of a commercial UPS.
I don’t know if I ever mentioned it, but APC and I have a long history of failures and injuries. I was knocked across a wiring closet by a plasma flash through the front grate of a 6kVA APC UPS in meltdown once. In 2017, I had another 2200VA unit on the bench spontaneously short out its battery pack and “bite” me pretty bad:
The burns self-cauterized, and I didn’t even seek medical attention. Of course the fingerprint reader on my phone has been useless ever since, but I digress. Needless to say, I will not touch or spend a dime on another APC UPS.
A footnote on the generator is that our town taxes permanent standby generators as a luxury. Many of the cheaper residential standby generator options are air-cooled and run on natural gas, which we do not have in our neighborhood. I want to get a “portable” diesel generator, and drop a siphon line down our heating oil vent nozzle with a pump to fuel the generator. We could run for a few days off of the heating oil supply, and it isn’t taxable as long as it is on wheels and not wired directly to the house…
