Thanks. I have a home Synology NAS for video and audio via Plex in addition to the router and wifi access point. I have one CyberPower UPS dedicated to the server and a second CyberPower UPS dedicated to the comms equipment. We have regular winter outages here in the north woods due to storms and tree falls. Our outages can run from minutes to hours and sometimes to days.
I initially wanted the power on for comms when we were away in the winter to keep tabs on the house, but I faced the same limited time problem you did with the built-in batteries in the UPS units.
I finally decided that the best solution was a whole-house emergency generator and an Automatic Transfer Switch. About 18 months ago, I had a 26 kW Briggs & Stratton unit installed and hooked to our natural gas supply line.
Of course, as soon as we installed the generator, our area invoked “Yhprum’s Law” (the inverse of Murphy’s Law — “Everything that can work, will work”). Since installing the generator, we’ve had a single one-minute outage.
I was going to go with the Generator backup, it would have been about $7K by the time it was all said and done, the power is usually up in 4 hours or so. But it would still need the 3 APC backup UPS hooked to the servers during Gen Start and Transfer. I will install 4 Solar Panels in the future so it doesn’t rely on the power coming back up to keep everything running. but it will go for 24 hours the way it is, once I put the panels in it will run FOREVER.
It's one of the natural laws, like watering your garden, during a dry spell and it, unexpectedly, rains an hour later.
Or you lose a tool, so you buy a new one, lose the receipt, then, immediately find the original.
