agreed, a lot of standby generators come with battery for the time from when the electric dies and the generator starts up.
The battery in most generators is just to start the generator. It does not provide power to the load; especially any $3k model.
I have a Generac 8kVA generator to run my office. I also have several UPS's on my servers and PCs.
The generator runs on natural gas and has an automatic crossover. The UPS's just need to run for 60 seconds until the generator starts.--
