Reason why you use a UPS on a pellet stove?

Have you looked at a passthru inverter? when AC is present it will charge the battery and power your devices and when there is no AC, it pulls from the battery.
not a ups but close. You can select the battery size you want vs what the UPS manufacturer gives you.
I've never used one of these like that but I don't see why it couldn't work.

 

You just need to shop around on that. Some have a very fast transfer function, some don't. One I was looking at and can't recall the name now stated it
would keep your electronics running during the transfer. They are not exactly cheap either, between the battery and the inverter you start to get close
to a lithium ups. Unless you already have the battery.

 

yea stupid expensive.
I have no idea on the quality of this brand but Aims PICOGLF25W12V120AL 2500 Watt 12V Pure Sine Inverter Charger claims a 10ms transfer and claims its fast enough for most equipment.
655 for it and a 100 ah lifepo4 at 300+/- and you're ahead (definitely cheaper batteries than 300 , just rounding up)

 

You can save $1 if you buy off 'Zon , but at least you get free returns if it isn't what you really need, or doesn't switch fast enough.

 

The roaring inferno is a scary proposition indeed.

When I designed the new controllers I included a "LATCHOUT RELAY"
Solid state one shot timer that has the time resistor circuit left open (Infinite resistance) So it turns on and does not go off unless the power is interrupted ......IF the power goes off even just a blip enough to kill the lights the latchout relay opens and the stove is dead....
The "Reset" button must be pressed momentarily to reset the system....Simple and effective
The control power to the Latchout is routed through the over temp snap switches.
Very low amperage...So the snap switches don't get the hell beat out of them....
If a snap opens the stove shuts off....If come home to a dead stove and the LED clocks are all fine....Then the issue was likely an over temp........We had this happen once...had a burn back up the auger tube.... There are two Snaps on the little stove...Wired in series....Anything happens...Stoves is off

The latchout is wired so the safety over temp snap switches run through a solid state relay and will also shut the stove off......

Anything Hinky and the stove is going to shut off....
A really short blip..."A few milliseconds" may not.....
We have one Alarm clock (LED) that will start blinking even at the slightest upset.....But the stove controllers will hold....

Main issue....IF THE LIGHTS GO DARK....The stoves will need to be restarted.....No worries of coming home to a smoke filled house....OR WORSE...

I have thought about a UPS so we can shut the stoves down and not get smoke in the house during as power outage....Then we can get the Jenny up and bring the Quadrafire up...

 

I have UPS' on both my stoves. Not to keep them "running" but the Harman's will sense when they are on the UPS and shut themselves down gracefully. I have APC 750 (no longer available and I recently got new 800 batteries for them). The size I have have enough juice for the Harman's to power themselves down (they pulse the exhaust fan). They are strictly to keep smoke out of the house in that case (the P43 is basically on a direct vent so no rise - the P61a has a good rise so should be okay, but why chance it?

The Harman's also know how hot they are, so if power comes back while there are still good coals (or low flames), they won't/shouldn't overfeed. The caveat to this is that some UPS's may not work like this for Harman's. Although they have approved certain Triplite as well as the APC units I have now. Additionally, my sotves don't have any electronic settings, just dial settings, so those aren't affected by a power blip or full power outage.

Of course that doesn't help you wince you dn't have a Harman

If your stove is sensitive to blips, the Lifepo battery stations may not be good even when used in a ups function as they tend to have a slightly longer switchover time. IDK, haven't tried mine in such a situation, just going by the talk on some of the FB pages.

 

Our stoves don't seem to mind "Blips"
We have never had any surges...We can get power drops and then depending...the reclosers will turn the power back on....
Reclosers sense a limb on the line or ??? and will shut down, then power the circuit back up and see if the problem still exists....3 times and then locks the power OFF

Many times small trash will fall on the line and burn off....or fall off if it is windy and this saves having to send a crew out to investigate.....
Not great during very dry weather...Around here the Power company sets the reclosers to open only with no resets in the dry times....

Power reconnects never seems to trouble the equipment...

When we get a power outage we disconnect the sensitive equipment until things are back to normal....

Our stoves are all direct vent.... An outage can cause a bit of smoke smell in the house....Not a big issue though....

I prefer the direct vent as it allows easy "Leaf blower maneuver " Only 5 minutes or less to clean each vent....No climbing on the roof either......

 

A pure sine wave would act as a battery backup, but most standard UPS won't last very long, thus the need for something like an attached marine battery for extended outages.

I've used my Ryobi power station , with 4 batteries at 40v 6.0ah, and that only lasts 5-6 hours of continuous run (let's see, 40v x 6.0 ah x 4 batteries = 960 wh - or something like that) . that was during a 3 day power outage so I actually attached the APC UPS to the Ryobi, plugged the stove into the APC, then when the Ryobi batteries died, the stove detected the use of the non-sine wave UPS, and shut itself down gracefully.

But, you did state at the beginning that you were just discussing blips (or enough time to pull the genny out), so most likely a pure sine wave UPS would be fine tool for the job.

 

Jay....you just need one of these....I'll give you a good price on it

 

Tad bit of overkill for one pellet stove......Woooo hoooo

 

I have about 6 UPS in my house. Mostly to avoid the annoying power blips for things like WFI and modems.
I also have them on my daughter's PS5 for a safe shutdown and all my TVs.

I have both my pellet stoves on them as they will run for 45min to 90min depending on settings to allow for a generator to be hooked up.

My wife works from home now so I bought three pure sine wave portable battery stations like Bogie has. Each is 300 watt capacity. Along with two lifepo4 20ah batteries and inverters. One pure sine one modified.

The small size is easy to move them around as needed for a power outage. And the 300 watt battery stations are nice because my wife can move them to the stove and plug in the UPS to them and get about 8 hours out of two of them. I would be home after that time to switch to genny.

 

Me too.
