Batteries are Cheap, Backup power is expensive


Dear Audiophiles,

To make a long story short I need to make sure my Internet devices stay on even when power is down for 24 hours, which on the South Carolina coast is realistic. 

I have an APC UPS 600VA which I though would do the job but it actually lasts less than 2 hours.  So I have been crunching the numbers and have really been surprised at how expensive an APC UPS is per minute of run time vs. modern battery based generators and DIY solutions. 

An APC UPS can be anywhere from $1.50 to $2.50 / minute of run time while an EcoFlow Delta for instance is around $0.50 to $0.75 / minute.  Not only is the EcoFlow cheaper but just has ten times better run times.  A single 1 kWh unit will keep my data closet running close to a full 24 hours.  I have too many devices in there which consume ~ 50 watts.  50 x 24 = 1,200 

I did in fact purchase a Delta 2 with back up battery for other reasons than the data closet, but when doing the research I also investigated DIY backup solutions and came across the idea of using a Renogy inverter/battery charger + 2x 12V LiFePO4 batteries.  It’s even cheaper than the Ecoflow but requires much more effort to set up.    I’ll do a full write-up on that soon. 

What have you done to back up your home devices?

@billpete  - Sorry I missed your post earlier.   Personally, an outdoor generator like a Generac or Kohler is out of my budget for now... but, assuming it was not they still have a 10-20 second transfer delay.  I would still need a very small UPS for my networking gear and PCs to ensure uninterrupted usage, such as being on a video call. 

You are on the right track though, having out outdoor generator would greatly diminish the size of UPS or battery back up I need indoors.  At that point, practically any UPS would be big enough to handle my data closet.

I believe underground storage of a propane tank only needs a minimum of ten feet from building or property line.  Up to 2000 gal tank.
