Battery Inverter setup?

Qusetions: I need to assemble a battery & inverter set-up to strength the heated pad inside doghouse for my two min pins. The heated pad draws thirteen watts in accordance to my kill-a-watt meter. In scenario of the an outage I want to get capable to preserve their pad heated for anyplace from 10-15 several hours at a time though i'm at do the job. I can crank up the genny when I get property. I suppose I will need a deep cycle battery but what dimension? much better however how do I determine what I will need? thanks

Answers:Great write-up on this type of point in the website link in the bottom.

A few of factors to think about: Two six volt golf cart batteries wired in sequence will do the job quite a bit much better than a deep cycle twelve v battery should you have a very strategy to revert to battery that kicks in only once the electrical energy fails. or else you may well come across you put on out a deep cycle create also promptly should you are constantly discharging and charging. Use an everyday car or truck battery in that situation. Sump pumps using a battery fall short about likely possess the change you will need, I'd exploration that if it is actually your circumstances.

To obtain the capability on the battery for your 15 several hours at thirteen watts steady draw, you'd utilize the subsequent instance. But does the pad draw thirteen steady? Two canines in an insulated canine property will not will need really very much exterior warmth if your property is sized adequately.


Watts = Volts * Amps.
13 watts = twelve volts * one.1 Amps
Batteries have an amp hour rating. The Sears Die challenging Deep Cycle is rated at 115 to get a twenty hour draw charge. (the way the battery is designed can differ dependent on meant use, so the draw charge is employed to deliver a standardized comparison) given that you'd like 15 several hours, the twenty hour charge will be the most relevant. so that you can pull 115 amps you will need one.1 steady, so that you get about ten several hours on that battery.

Now, an additional difficulty is usually that most inverters will shut off when voltage drops beneath a particular position. search in the very first website link for additional information on that.

They also market DC heating pads for autos and for pets.
