Like the idea of multi-room UPS. Question, once the UPS battery run out during a power outage, is there any other power generation (Solar, Propane or gasoline) as backup (aware of servers will consume more watts than it can generate)?
Yes, I have a 27kw Natural Gas standby generator with an ATS. It takes 10 seconds from power failure, to it switching to generator power. So, the UPS just bridges that gap
