Running pellet stove on car adapter

a 2000 watt continous woll drian 3 truck batteries in about 90 mins

Without the igniter running on my Quads, they draw a max of 200 watts each. Your bigger worry would be how 'clean' the 120 volts is that is being fed to your stove's computer, if it has one.

Taken from the owners manual, Enviro Mini.

ELECTRICAL: The use of a surge protected power bar is recommended. The unit must be
grounded. The grounded electrical cord should be connected to a standard 110-120 volts, nominal
average 2.0 Amps (4.1 Amps peak), 60 hertz electrical outlet and also must be accessible. Ensure the
polarity to the outlet, the unit will be plugged into, is correct as incorrect polarity can affect the unit’s
operation. If this power cord should become damaged, a replacement power cord must be purchased
from the manufacturer or a qualified ENVIRO dealer. Be careful that the electrical cord is not trapped
under the appliance and that it is clear of any hot surfaces or sharp edges. This unit’s maximum power
requirement is 184 watts (600 watts peak).

Don't even bother with those, they're junk. Spend an extra few bucks and buy a decent UPS by APC and you'll be fine.

Well to me anyone that lives in a area where it gets really cold and power outage is a possibilty a backup generator is a must.

an average computer ups is only going to run you for 10-20 min depending on the size of the unit.

Ideally, you want a pure sine output device.
I'm looking into getting 3 or 4 AGM sealed batteries, pure sine invertor, and charging methods including solar and a home-made generator with a 5hp small engine.

Most UPS's run on small sealed lead acid batteries of the 12volt variety. It is a simple thing to wire a deep cycle marine battery to the UPS and drastically lengthen its run time. All the UPS's I've seen have an annoying alarm to alert you that the power is out and now you are on backup power, the intention is you will shut down the computer, and end the drawn on the UPS. A good question is not how long the UPS will supply power, as this can be extended indefinitely by adding much larger batteries, but is it designed to operate continously? Ideally you have a generator that takes over from the UPS shortly after the power shuts down. Or you have a good pure sine wave inverter and several large deep cycle batteries to handle the extended running time. At some point however, you will need to recharge batteries so sizing an inverter backup can be difficult. How long will the power be out? 5 hours or 5 days? It makes a difference. A UPS and a Honda EU2000i generator will cost about twice what a pure sine wave inverter and two or three deep cycle batteries will cost. But the Honda EU2000i will run your stove, fridge, tv, etc. as well. You can guess what I own..... My EU2000I ran for 5 days continuously after Irene. Very quiet, you cannot hear it, nor can the neighbors, and only just over 2 gallons per day to keep the basics running. RT

I looked into that, and would advise against it. The charge controllers in these ups's are not cut out for running large amp/hour batteries and may either cause damage or shirt out and fry. It can be used as a backup to the backup, but i wouldn't leave it plugged into the wall to charge like this. Keep in mind, batteries also leak gases- even the sealed ones. AGM as the safest type for indoor use.

Most stoves require about 200 to 400 watts continuous to run. The inverter must be a pure sine because most controllers use TRIACS and require a sine wave. A typical Marine battery is rated at 130min reserve at 20 amps.
A stove using 300 watts requires 2.5A at 120V. That equates to (2.5/.9)*(120/12) = 28 amps from the battery. Using the marine battery at 28Amps gives 130*(20/28*.95) = 88 minutes or almost 1.5 hrs.
Realistically I would only run for 1 hr and then charge the battery. Completely draining & fast charging a battery shortens the life by a large amount.

Even using one of those Harbor Freight 800W buzz saw generators for $90 would be cheaper and last longer.

i read a few posts of harman accentras running eight hours on one marine battery. i also remember a write up where a guy converted an apc to operate and charge on a series of deep cycle batteries. it wasnt for the novice though.

im curious, can you hook the inverter up to a car battery while its running?

Not to highjack at all, but along the same lines. For those of us that have a cheapy generator, is there a way to clean up the output so the stove is happy?

A line conditioner or UPS will get you as close as you're going to get.

Back-UPS Pro 1500VA, 2 hours of runtime at 200 watts. $179.95. Don't use the ignitor.

Anybody know of a good pure sine wave inverter. They are all over the place in price

Yes you can. Here is a good link on inverters.

The do sell power conditioners (rack gear for musicians, light shows, etc) but they aren't cheap... almost might as well just buy a pure sin eu2000

I have this: Xantrex SW600, true sine wave, 540 watt continuous, 1200 surge.

We don't even know what kind of car this person drives. Maybe it's a Hybrid?

RWThomas1, on the Honda EU2000i generator, how do you know it's pure sine wave output? I read through the manual and see no such claim. I just see an inverter and noise filter in the schematic. Like to know before I plunk down more money.

the entire eu series is pure sine output

Here you go, as clean or cleaner than what you get off the grid. Click on the "advanced inverter technology" link http://powerequipment.honda.com/pro...tion=P2GG&modelname=EU2000i&modelid=EU2000IKN

Its a simple thing to add a set of taps to any UPS battery. When the power quits, hook the marine battery up in parallel, then disconnect the UPS stock battery if it makes you happy. Any deep cycle can be stored with a Battery Tender, or similar smart charger, plugged in to maintain the battery. There are inverter/charger units available that will charge a battery bank while acting as a transfer switch from line power. The inverter will automatically switch to battery power when the line voltage quits. This is common stuff in the marine world.

I'm a believer in a small inverter style generator. I have a Honda but Yamaha and others make comparable units. These small generators will run the essential parts of your house as well as the pellet stove. The inverter/battery/ups will ONLY do the pellet stove. I makes sense to have a small UPS for the pellet stove since if the power does go out the pellet stove will continue to run and likely you will not have it back up smoke into your house. Extending running on the UPS is impractical and only serves the stove. The small inverter generator will run a fridge, TV, computer and the pellet stove. Most of the smaller inverter generators will not run a microwave, except maybe just the microwave, so its definitely not a "whole house" solution. I can live with just the essential electrical demands met for the extremely low noise and low fuel use the inverter designs offer. RT

Not sure where you got the 2-hour figure... APC claims 33 minutes at 200 watts. See Estimated Runtime on this page to change the values:
