UPS battery for DS918+ 20 minutes -3 hours

I have recently purchased a Synology DS918+ unit and configured it with two IronWolf Pro 10 TB on RAID 1. Going to add two more IronWolf Pro 10 TB on RAID 1 in near future.

Currently I am having power blackout problem on a daily basis in my area. I will be happy to get 20 ~ 30 minutes backup and even more if selected model fits in my budget.

I came to know CyberPower and APC are two of the most popular brands. Which UPS brand and model should I get for my Synology DS918+ unit. Please suggest 2 to 3 models marking best, better and good according to my budget.

I came to know across two terms called PFC and AVR. Does it matter for my NAS model.

What can I connect to a NAS?

Wireless Speaker Sonos

The great thing about Sonos is that you don't need to pay for music subscription service. With the cheapest NAS at home like DS115j or any other, you can have your backups done for all of your devices and still use your network drive as a Sonos music library. Sonos will connect to your NAS via your network and let access your provided music library. If you have little more of IT knowledge, you can even set up your Alexa or Sonos with Alexa built in to play music on your voice commands ("Alexa! Ask DS Audio to Play Music!").

Casting devices

Nowadays it is so cheap to upgrade your old TV and make it smart. All you need is Google Chrome or EZcast alternative plugged into your HDMI port at the back of your TV. Now you have great functionality added to your TV to send a video file directly from your NAS to a TV. No need for wires and chargers and other mess. You can use your phone as a remote to go to your movies or family videos and cast that content on your TV during family or friend gatherings.

You may not have a smartphone, or you just simply prefer to control your content with a remote in that case Amazon Fire TV will be a great addon to get to your TV. It also plugs into your HDMI port and will play content from your NAS to a TV. No wires no mess.

nVidia Shield TV

It gets even better! If you want some more entertainment and all previously mentioned functions - nVidia TV is a great thing to get. You can use it for playing games and watching movies from your NAS. The greatest thing is - shield TV does video transcoding. So even if you have a cheap NAS with a weak CPU, in a combination of shield TV you can now automatically on the fly change video file size and format for a destination device. It is a great way to reduce network load and let older devices to play video content which normally was not supported on the device.
