This article is about daisy chaining UPSs into each other's AC outputs. I hope you're not doing that off grid. Daisy chained UPS means the energy takes the path of DC battery > AC inverter > DC rectifier > different DC battery > AC inverter > DC rectifier to whatever device you're powering. You could be losing up to 20% of the energy (server uptime) at each step of the daisy chain. And since there's only one path for power to take, if anything fails, it all goes down. The article's solution is super simple, just use them in parallel instead.
- madaxe_again 3y agoUPSs typically operate in passthrough mode unless a deviation in supply occurs - so no efficiency loss day to day - and no, I don’t chain UPSs, but as I said, the house batteries are essentially big damn UPSs. Also, not particularly caring about efficiency currently as we always have more energy than we can use, and I’m currently looking at filling a shipping container with sand as a dump.
- geor9e 3y ago>UPSs typically operate in passthrough mode Oh, that makes a lot of sense. In that case, daisy chaining two sounds like no big deal. >filling a shipping container with sand as a dump That's pretty cool. I didn't know private folks were doing that.
