Question about Panasonic PV-C1320 13 in. TV/VCR Combo

I need to find out how many watts the tv takes to see if i should buy the 400 watt dc to ac converter.

Here's the link for the user manual if you need it; http://service.us.panasonic.com/OPERMANPDF/PVC1320.PDF Check page 39. 120vac - power on = approx 69W I wouldnt get an inverter too close to that figure, but a 200w inverter should do - just check the inverter specifications to verify if the rating is actual power output - many inverter manufacturers are a little creative with their model names etc, but the real info has to be somewhere on the box. If in doubt then the best way is to evaluate your battery system capacity and usual recharging input, and match the current drawn by an inverter to half that figure, see what power inverter size you can manage. if you buy bigger, you get more watts per dollar usually, and you may want any surplus capacity later for another item. Also running inverters up towards their maximum often will shorten their life dramatically. Hope this helps :)

Inverter Generator Benefits

performance chips of BMW.

The EU3000 series generators are inverter generators. The generator features an alternator, which produced high-voltage, multi-phase AC power. This power is converted to DC power and then converted back to AC. This process is controlled by a microprocessor and is necessary to provide stable, consistent power capable of running equipment sensitive to power surges. This type of generator provides higher fuel efficiency and lower operational noise ratings in a lighter model than home and work generators produced by Honda.

The Honda EU3000i Handi is a 3,000-watt inverter generator that features wheels, folding handle and a recessed convenience light. The engine is a Honda GX160, which features a 163-cc displacement. The AC output is 120 volts, with an average rating of 2,600 watts and a maximum production of 3,000 watts. There are three receptacles to include a 20A, 125-volt duplex and a 30A, 125-volt locking plug. The DC output is 12 volts and 100 watts. The EU3000i can hold 1.56 gallons of unleaded fuel, which will provide consumers with 3.6 hours of run time at 25 percent load for 7.7 hours.

Your calculations is correct - 220 X 0.7 = 154 watts.

If your fridge only runs on 220 volts then you need solar panels that charge 12 volt lead acid batteries and then use a inverter to convert 12 volts DC to 220 volts AC.

there is no such thing as "ac/dc" current-its either one or the other--if its a 120 Volts then chances are it is AC already-at 60hz---the 15 Watts or any Watts is the amount of draw from the unit-not the power supplied to it- Watts= Volts(supplied)/Amps(being used) if you only want to supply 15 watts then reduce the amps (with a fuse) to .125amps

Question does not seem to match this inverters capability.

INFO:

This Power Inverter converts vehicle’s 12-volt DC power into household 115-volt AC power. AC and USB outlets power and/or recharge personal electronics.

We have owned one of these Power inverters for over a year now and have run a great deal with it, from TV to drill press PC and any thing that was small and that could run from my car. Very nice product.

SET UP: Connect wires. ensure correct polarity, push button on top. Plug in 110 volt appliance.

Hope this tip was of some use.

your going to blow up your converter then,,,,

the compresor will pull far more than you have to start with

If you are referring to the RoadPro
RPPI-250
2000 Watts Continuous Power
2500 Watts Power Output @ 10 Minutes
5000 Watts Peak Power Output.
A small fridge will use about 500 -700 watts, with startup wattage at around 2000watts.
So, a dorm fridge will work fine.
the RoadPro converts DC to AC voltage, so a regular 120 volt dorm fridge will work.

There are adapters to a car lighter for all kinds of AC plugs but not usually very strong. Laser printers can take alot of power. How many WATTS does the powers cord say? Here is one that does a 160 continuous and 300 peak. Check the amps too before you buy, but there are a multitude of these they are called DC to AC converters.

If you want to get more precise, figure out everything in terms of power (watts).

Basic electrical rule 1, 2 and 3:

voltage x current = power

or re-arranged:

current = power divided by voltage

or re-arranged:

voltage = power divided by current

For example, 12V X 2 amps = 24 watts.

or another example, 400 watts divided by 120 Volts = 3.33 amps

A 55W headlight that uses 12V would draw 55 /12 = 4.6 amps @ 12V

A 55 watt light bulb in a lamp at home would draw 55 / 120 = 0.46 amps @ 120V

As the previous post mentioned, inverters are not perfect when convertering 12V into 120V. If the converter consumes 1000W from the 12V battery, then a 90% effecient converter would generate 900W of 120V AC power best case. The other 100W is lost primarily as heat.

The other thing that gets tricky is that these ratings and the formula above are used for resistive loads, like light bulbs or hair dryers. Anything with a motor or transformer is considered an inductive load and can get much more tricky to calculate.

Consequently you need to give your self a safety margin when figuring out how big an inverter you need.

How does work in a practical sense?

Lets say you want an inverter for TV, DVD and Sat. Receiver. Look at the back of TV or in the manual. It should say how many watts it consumes. Lets say it is 400W. The DVD might be 100W and the Sat. receiver 50W - just as an example.

400 + 100 + 50 = 550 Watts. (just as an example)

You might think, well no problem, I'll use a 600 Watt inverter and have 50 watts left over. Depending on your inverter, that 600W might really be 600 x 90% effecient = 540 Watts of AC, less a 20% margin of error for the inductive transformers in the electronic of the TV, DVD and Sat. receiver 540 - 20% = 432 Watts.

Now you can see your 600 Watt inverter isn't big enough to do the job.

If we really need 550 watts of AC, add 10% to make up the effiency loss, then add a safety margin for inductive loads.

550 + 10% = 605 + 20% = 726 Watts.

Sounds more like an 800W inverter fits the job.

What does that mean in terms of wiring the 12V batteries to the inverter?

from the formula above:

current = power divided by voltage

In our example, we have an 800W inverter that runs on 12V

The current would thererfore be:

current = power divided by voltage

current = 800 watts divided by 12V

current = 66 amps.

That is important info because you can not use light gauge wire to carry 66 amps worth of 12V to the inverter nor could you use a 20A fuse to protect your inverter.

Now that's a lot of science for a guy who just wants to run a toaster on an inverter right?

800W / 120V = 6.66 amps

Using garryp's ratio 11:1, 6.66 x 11 = 73 amps.

That is a good ratio with a good safety margin.

This is all just MHO and should not taken as solid technical advise. In other words, don't blame me if you blow yourself up.
