Discussion Overview

The discussion revolves around the feasibility and methods of using a 12v battery to power household appliances, such as computers and TVs. It explores the need for additional equipment, specifically inverters, and the considerations involved in such a setup.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the possibility of using a 12v battery for household appliances and seeks guidance on the necessary equipment.
  • Another participant suggests that an inverter is required to convert the 12v DC from the battery to the AC needed by household appliances, noting that automotive supply stores typically offer these devices.
  • A further contribution emphasizes the importance of using a Sine Wave or Modified Sine Wave inverter for compatibility with electronic devices, as plain inverters may not be suitable.
  • Participants mention that a large deep cycle battery is necessary for running appliances for a reasonable duration, and that the capacity of the inverter and battery investment will significantly affect performance.
  • One participant shares a personal recommendation for a supplier of inverters, detailing their positive experiences with various models purchased from them.

Areas of Agreement / Disagreement

Participants generally agree that an inverter is necessary to use a 12v battery for household appliances, but there are differing opinions on the types of inverters and batteries that are most effective. The discussion remains unresolved regarding the best practices and specific equipment needed.

Contextual Notes

Participants express varying levels of knowledge about inverters and battery types, and there are assumptions about the compatibility of different appliances with the power provided by inverters. The discussion does not resolve the specifics of inverter types or battery capacities needed for different appliances.

Who May Find This Useful

Individuals interested in alternative power sources, DIY electronics enthusiasts, and those considering off-grid living may find this discussion relevant.

12v to power household appliances??

How can I use a 12v battery to power household appliances such as computers/TV ect...
Do I need some type of converter? I was told that a 12v battery won't power household appliances because they are designed to run off of the 100v house circuit. Where should I start?

Welcome to PF, Jagman.
You need an inverter, not a converter. Most automotive supply places can set you up with one. They're a bit pricey, but not too bad if you really need one. Only problem is, the biggest one that Canadian Tire sells is 400 watts. It costs $60. I don't know about other suppliers. RV dealers might have something bigger.
 
In addition to what Danger said.
Most electronic equipment is not real happy with plain inverters.
You are going to want a Sine Wave or Modified Sine Wave inverter.
The average computer or TV might run 30 minutes to an hour on a large deep cycle battery like they sell for boats in the auto supply store.
The "Deep Cycle" part is important if you want the battery to last a while.
You can get inverters up to 2000 Watts, but to run one for any length of time is going to be a major investment in batteries.

Check these people out, i have bought 1- 5000Watt, and 2- 2500Watt, inverters from them and have been pleased with all units. At the time, they came with cables(4 on the 5K) and were, sales tax and freight free. (i have had no problems with any units)
Before finding this source, i bought a Vector 3000Watt, and a couple of smaller units, they required sales tax and cables
