G+_Jason Perry Posted September 17, 2016 Share Posted September 17, 2016 So next thought stemming from my previous post. If I have a 67 Watt load, how long will a 450 Watt power the equipment for? I can't find anything that says Wh or Ah on the product info. Would it be as simple as 450/67? Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted September 17, 2016 Share Posted September 17, 2016 Just grab a 60w bulb and test it out. Real world results always more useful then theoretical. Link to comment Share on other sites More sharing options...

G+_Jason howe Posted September 17, 2016 Share Posted September 17, 2016 Are you talking about DC - DC power or DC-AC power Vac at 120 v likely 20-30 min, and at 220/240 vac 5-15 minutes DC-DC likely 5-10 hours on a single ups domestic grade battery.. Probably a cuople of days on the standard 1-1.5 kw on the small size ups batteries mod the chassis to accept the larger kind you might get a couple of weeks on DC only on vac componentary use you might see 4-24 hours on limited replace rear with an AC and a DC in with a DC out only panel you might get a month out of it depending on DC current load out to what you are trying to power it. If you are looking setting a 12/24/48/96 VDC system vac/vdc powering options for running 12-48 VDC and 120/230 vac capable hardware .. Note in a prepping situation you will likely start looking at 12/24 vdc and AC powering options and propane cooling typically what would be seen in a camping trailer or caravan as you will..

G+_Jason Perry Posted September 18, 2016 Author Share Posted September 18, 2016 Found the batter specs online and if I did the calculations right I have 42 minutes of run time on a brand new battery apc.com - APC Back-UPS 650, Canada|APC Link to comment Share on other sites More sharing options...
G+_David Wiggins Posted September 18, 2016 Share Posted September 18, 2016 Don't forget to take account of temperature on these things. To hot or cold can kill them. For what I have something in the 40-70 degrees Fahrenheit range is the sweet spot. Link to comment Share on other sites More sharing options...
G+_Jason howe Posted September 18, 2016 Share Posted September 18, 2016 For DC modification I believe most people in this field are using the old 1-1.5 KVA models.. due to battery loadout Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted September 21, 2016 Author Share Posted September 21, 2016 I have seen some great UPS mod videos. Not sure I want to deal with hacking it apart, because, I don't want to make my father she'll out money for it then void the warranty. Link to comment Share on other sites More sharing options...
