    To answer we need to know 4 things:


    1. What model exactly is the whistler inverter? (so we can determine the efficiency)

    2. What is the amp-hour rating of the battery?

    3. What wattage rating is the inverter?

    4. What is the total wattage of the appliances you want to run?



    We have to know all four to estimate the current draw and the length of time for the battery to fall below the inverter shutdown point.



    And safety warning: remember - cigarette lighter plugs won't handle more the 130 watts of power, if you need more than a couple light bulbs lit you need to wire the inverter directly to the battery(s) (using a switch and fuse of course).

    if you going to use it while driving the car will keep the battery charged if you use it parked it will depend on how manhy watt is your tv or radio etc. usually small stuff use little so it may last few hours.

  • Norman Al-Anbar Sep 08, 2009

    you neeed to find out how many watt it use and how big is your battery I have forkleft battery old one I usually charge it every week and I use it for my house, tv, freezer, etc. Normal batteries usually last few hours if you have small sytem.

  • Norman Al-Anbar Sep 08, 2009

    yes you can use 2 of them to last about 18 hours...

    if one only without recheging it may last few hours...need to mnow how many amp your battery and how much use your system to be exact

Generator not powering RV


You need to find out if the generator is providing any power at all, when its not connected to the RV, get it to power something else. If it does that OK you have to suspect the inverter or some of the wiring in the RV, did any wiring near the inverter get wet?

WHAT IS A POWER INVERTER?


A power inverter is an electronic device that converts electricityfrom one form to another. Power inverters have become more popularrecently as the technology has become more efficient and much moreaffordable.

The most popular use for a power inverter isconverting battery electricity into mains electricity. For exampleconverting your car batteries' 12 volts DC into mains electricity 240Volt AC (Australia) or 110 Volt AC (USA).

WHAT POWER INVERTERS WILL HELP YOU DO
  1. Power inverters enablemains operated electrical equipment to be used even where there is nomains outlets, like in your car, caravan or even on your boat!
  2. Powerinverters bring creature comforts from home when you go camping orcaravaning allowing you to use your TV, fridge or electric shaver infact most of the normal mains powered conveniences from the home.
  3. You can charge your laptop in the car even if it doesn't happen tohave a 12 volt adapter. In fact a power inverter can be a very handygadget just to have in your car for those times you need to use a mainspowered appliance while you're away from a power socket.

WHAT TO LOOK FOR WHEN BUYING A POWER INVERTER
Apartfrom looking for a good quality well priced product there are a coupleof important elements to consider when selecting your power inverter:

HOW MUCH POWER IS ENOUGH ?
Powerinverters come in a range of power capacities so selecting the rightone for you is very important. Your power inverter needs to be able toprovide sufficient power for the equipment you want to use it with.
Here is a brief check list:
  1. Check the power consumption for the device you want to power
  2. Allow an additional 20% free board
  3. Add the power for all the devices you want to run at the same time
Note also that devices with induction electric motors like an power saw mayrequire 3 to 7 times the operating power when they start.
Usingan under-powered power inverter may damage it or the appliance you aretrying to use, so be sure to check the specific wattage requirementsand operating instructions for appliances / tools to be used.

PURE SINE WAVE INVERTERS
Normal mains power is known as Alternating Current (AC) and is a sine wave shape like the black line in the drawing below
Pure sine wave (black) versus modified sine wave (red)
Atypical power inverter produces a 'modified sine wave output' like thered line in the drawing above. While this works for most appliances,light dimmers, variable speed drills, sewing machine speed controls,some laser printers etc. will not operate correctly with a modifiedsine wave power inverter.
Pure sine wave power inverters areespecially designed to provide a more accurate sine wave output and socan be used with these appliances, but unfortunately they are moreexpensive.
Check with your with appliance manufacturer or itsspecifications to confirm if you can use a conventional power inverteror will need a pure sine wave inverter.
WARRANTY
One of thegreat things about electronic equipment is there is no moving parts(although there is a fan in some models) so you can expect a longserviceable life from a power inverter.
STANDARDS
Powerinverters generate dangerous mains voltages so ensure the product youchoose is approved for use with your mains voltage and supplier.
Powerinverters can also generate electro-magnetic radiation that caninterfere with other electronic equipment such as radios transmittersetc. Check for compliance with relevant standards such as C-Tick etc

SAFETY
Powerinverters can generate potentially lethal voltages so the utmost ofcare should be exercised using them to avoid accidental electrocution.

SUMMARY
To select your power inverter carefully check the power requirements for the appliance(s) you intend to use it with.
  1. Start power - Allow up to seven times for an induction motor
  2. Operating power - Allow a 20% margin
  3. Pure or modified sine wave

WILL A TRACE 2000 WAT INVERTER RUN A RV 15000 BTU AIR CONDITIONER


It can but you are not going to do it off a single deep cycle battery, You will need to have some robust batteries to sustain it. But that will almost need to be the only thing on that inverter.

It might be better to spend a little more and get the Air conditioner that can operate on 12 volts or 120 with the flip of a switch.

Look at the data panel for the 15,000 BTU AC. It's current rating should be right around 12 Amps at 120VAC. Which is 1440 Watts. Startup is when there could be a problem. Especially when the compressor approaches a near lockup condition. Current draw can be double that of normal operation Even though it is within the surge rating of the inverter- the batteries have to be at their peak at all times.

WILL A TRACE 2012 INVERTER RUN A 15000 BTU RV AIR CONDITIONER


According to specs, they will take a 44 amp AC power surge. Obviously number and type of batteries as well as battery condition , etc, plugged in, not plugged in to outside hydro, or generator all come in to play here, but a 15,000 BTU roof AC will only draw, 15-17Amps AC when compressor kicking in, ( or less on some new models) and should level out at 12 -13 amp draw after. As well, this will depend on proper wiring to and from main panel as well as AC unit, and incoming voltage, AC unit condition ( cleaned and maintained properly) etc.

Inverter


Are you wanting to install circuit breakers on the DC (battery) side? If so, you won't need them to protect the unit as it is already fused. But, it would be a good idea to install them as close to the battery so that if a wiring fault develops in te cable going to the inverter, it would be protected as well.

For the AC side, breakers are sized according to the wire size, not the capacity of the inverter. But, you can always use a smaller size if you want to try and protect the inverter from overloads as well. Your inverter is rated at 1000 watts, which is a bit over 8 amps of AC current. Use a 10 amp circuit breaker, and don't use smaller than 16ga wire for short distances. Use larger guage wire (12ga is 20amp residential requirement, 14ga is 15amp residential requirement) for the longer runs.

This inverter is not designed for a permanent install, its not intended to be run continuously. There are inverters designed for this, you can find an idea of product selection at rv suppliers, alternative energy shops, etc.

I have a 1000 Watt Inverter, along with a regular car battery when the electricity goes out; Question: Can I use the 1000 Watt inverter and connect a 100 amp, deep cycle battery? I use regular house...


Yes, just be sure connections are heavy enough wire, and obviously the inverter uses 12 vdc input. Hook jumper wires positive to positive, negative to negative, on all 12 volt batteries. Deep cycle batteries will work better than car batteries. Just remember, when re-charging them, that they last longer when charged slowly, so don't use a high amp setting on charger and to monitor them closely, and do it in a well ventilated area, away from any ignition sources.

Can i run my minn kota 30 trolling off my power box


Are you referring to an inverter by a "power box"? That term doesn't really describe the device. I'm going to assume it's an inverter you're talking about, a device that takes DC and turns it into AC. I'm not sure about that, but you should be able to plug a converter (turns AC into DC) of the right voltage, 12 to 14 volts DC into a generator on the boat and run it. I'm assuming the trolling motor runs off 12 volts DC and NOT gasoline. Be sure to check that before doing anything. Most do run off a large car or RV battery. Lead Acid Batteries for boats and cars produce 12.7 volts DC if they are in good shape and should have six cells (about 2volts per cell). 6 volt batteries are somewhat rare these days and have 3 two volt cells. Two of them in series will also power it.
Thanks for asking that question ... I like to fish also.

I think the problem might be your battery setup.
First of all, these batteries are not deep-cycle batteries they may not tolerate this kind of usage. Secondly, if you have 20 batteries connected in parallel they could end up working  against each other (draining each other) all the time.
You might do better with 2 very large 6 volt deep-cycle golf cart or fork lift batteries.

Power Supply How To


Because inverters operate from a DC (Direct Current) power source, usually a battery bank (one or more batteries), the battery source will have to be recharged at some point. (Remember that a battery discharged more than 50% is probably close to being dead.) Most cars and trucks recharge their batteries from an onboard alternator. Depending on the inverter load and runtime required, most power use applications will be covered by the charged battery, augmented by the operating alternator supplying a continuous charge to the battery. If the load is large (air conditioner, large draw power tools, large microwave, food freezer, ice cream machine, etc.), the user should verify that the installed vehicle alternator is of large enough capacity to operate the vehicle's power requirement as well as to fulfill the capacity of the inverter load. If it’s not, a motor throttle installation may be required to carry a small load, a larger alternator may be required, or a larger alternator, battery isolator and additional onboard battery bank may be required in order to meet the power requirement of the large load. Remember: it takes 12 DC Amps (at 12 VDC) to run 1 AC Amp (at 120 VAC single-phase) of power because there are voltage and efficiency factors to take into consideration.
