If you run a UPS, (no, genny's don't count)
Please post your model, and about how long it powers your stove for when the power is out, and if it is capable of starting it up from a cold start, no power.

I'm in the market to upgrade to a larger unit (mine gives me about 4 min, and doesn't have enough watts for a startup cycle)

what mod do you have?
 
My UPS are old, but still do the job fine.
I only keep them for short blips in the power now as I have a standby generator that
fires up in 30 seconds.

Prior to having the standby, I could get about 45 minutes out of the UPS if the stove was
running on low. This gave me plenty of time to get out the portable genny.

Never tried to fire it up from cold on the UPS, but I am sure it would run out of time before
the stove even got going. Ignitor takes alot of juice.

UPS model in my sig.
 
I have an old apc 810 watt that was on my computer. it will keep it running, but it's not enough to turn it on when it's been off. it only has 2 smaller batteries in it, i think they total about 2ah. I'm looking to go to something with a 10ah battery bank.
an invertor genny is in my future, but i just don't have the budget for it right now.
 
Well, i eneded up picking up a Cyberpower CP1500PFCLCD UPS for just over 200 on amazon. 900 watts. 3-21 min run time depending on load the site says, so let's hope it buys me some time for short power outages.

An invertor generator is still on my todo list.... but likely won't be affording it this winter. Too many other things going on and bills to pay for that puts my 'hobby' to the back burner (pun intended)

When you have it hooked up the display will give you a time off how long it will run at the watts you are using...mine was fairly accurate as I pulled the plug and watched the clock
 
You might be better off with a deep cell 12v and an inverter. I'm sure you would get much longer run time.

EDIT:
On second thought, you probably want the UPS so that the stove doesnt shut down in case of a power failure.
 
Yeah, I looked into a battery bank w/ solar or a charge controller, etc, but the down-time maintence and gas-leak of indoor storage (in my living room) is not something i'm preparred for. Plus, it's more expensive to set up with a good invertor.

With Sandy headed my way, I jumped the gun on a Hyundai 2200si inverter gnerator.

2200 peak, 2000 norm, comparable to the honda's and good reviews on amazon, for half the price of the honda. Considering i've had hondas in the past and currently drive a hyundai, lol i figured it was worth a try. I just hope amazon gets it here on time. It should be here monday.
 
yep.... i've owned a cheapo harbor frienght one before so i'm fmailiar with the power-on cycle of it.
 
I finally got the UPS all hooked up proper...

Looks like (assuming it's lit) on setting 3 (of 5, where i normally run it) it has a remaingin time of 71 min when the auger runs, and 121 when it doesn't, flucuating. So, I should be able to get over an hour and change out of this ups alone.

Now, i just need to lose power when it's cold out. heh i didn't even have it on for Sandy, and I didn't lose power any way.
 
Has a cyberpower 1000 watt from costco, year ago it lasted 10 mins on a 75watt pellet stove, returned it pronto!!, made my fans hum too = junk, pure sine my ASS

You must have had the wrong model.....my Cyberpower UPS is pure sine wave and the pellet stove runs perfect. I returned another model that was a stepped wave and it made my motors sound labored.
 
Does anyone know what the formula is to figure run time on a UPS? I'm drawing 3 amps max on my stove's highest setting, normal it's around 2 amps..

One of the websites, APC or Cyberpower has a chart for the different models and different wattages and how long they will last. I was surprised by how little mu stove uses while running...on high it is 153 watts and 178I when the auger turns.
 
Run time should be battery capacity (in ampere hours) divided by [Watts out divided by efficiency divided by 12 (battery voltage)]​
hours=Ah/[Wout/eff/12]​
Watts out is the actual load​
efficiency may change with load and may be dependent on wire size​

Any of you guys with APC's, Cyberpower's etc can get away with longer run time. (Now this will void warrantee) Parallel a deep cycle 12v, car, or UPS battery into the mix.

I have a 750va APC and can run my englander as long I want with the 3 car batts, 2 boat batts, even the lawn tractor batt!

ow is this done?
 
Your ups battery is likely attached by (female) spade connectors. If you disconnect from the battery cut them off, and reconnect with new connectors and a parallel line to an additional source (12v) you are essentially piggybacking the 2 sources.

I'll try to post a couple pics later.

Here are a few pics, a poor schematic, a oem "style", and 1 of a paralell set up **note this was done just for demo**...as I am @ work

Feeding it a charged deep-cycle is common.

However, i would recommend NOT charging it (ie, wall power exists) this way through the ups's charge controller. This may cause issues. If you have a pre-charged battery lying around, sure, plug it in if you need it. Once it's dead, bring it back out to your truck or generator/etc.

Be aware also that you should really only hve AGM type batteries indoors. Other types leak gasses and should not be stored or discharged indoors.
 
My ups, batts etc all reside in my garage and feed a dedicated outlet for the stove in the dining room (adjacent wall) so all the electronics are behind the scenes.
 
can anyone confirm that the battery setup on a Cyberpower ups is 12v and not 24v ? yes they use 2 12v batteries but are they in parallel or series ? if they are in parallel you could add a single larger 12v battery , but if they are in series , you'd need to parallel them with 2 12v batteries that were in series .

cheers Woody
