take you generator in and have the output tested for correct voltage and sine wave configuration

electronics rely on a perfect sine wave ac current as a manufactured sine wave affects electronic components such as capacitors, transistors and diodes

generator sets that run an alternator ( not an inverter ) have a pure sine wave and have less affect on electronics.

go google and type in search headings like ---sine wave, inverter sine wave, sine wave affects on electronics, alternator operation and inverter operations and then you may get a pointer as to why your inverter gen set is affecting your electronics

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

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:

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.

WHAT POWER INVERTERS WILL HELP YOU DO

- 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!
- 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.
- 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.

Here is a brief check list:

- Check the power consumption for the device you want to power
- Allow an additional 20% free board
- Add the power for all the devices you want to run at the same time

- Start power - Allow up to seven times for an induction motor
- Operating power - Allow a 20% margin
- Pure or modified sine wave

Yes you can and no it won't harm it unless something is wrong with it or the charger.

The inverter output doesn't get to the battery, just the chargers output.

It is becaus the inverter erradiate EMI (Eletro Mechanical Interference) and the EMI is picked up by the TV antenna, try moving them a part as far away as you can from each other (the inverter and the TV antenna), there are also some filters you can pusches, but enven with all that stuff you could end up with EMI any way so don't spend to much,

Good luck!

The manual states when running on AC, it is the same sine wave ouptput that comes in. When running on DC, it is a modified sine wave.

The rms voltage is what counts, because it tells how much power the output will deliver to a resistive load. Inexpensive multimeters on their AC ranges are usually average-responding rms-calibrated meters. This means they measure the average of the absolute value of the AC component of the signal, and display that average multiplied by about 1.11 (actually, pi over sqrt(8)), the ratio of rms to average value for a pure sine wave. That way, the meter will give the right rms reading for a sine wave.

If the signal is a square wave, where the average and rms values are equal, the average-responding meter will read 11% too high.

Many inverters put out a modified sine wave (MSW), which sits at zero for a while, goes to a constant positive level for a while, goes back to zero for a while, and goes to a constant negative level for a while to complete the cycle. The positive and negative parts of the signal have the same magnitude and duration.

The rms and average values of an MSW depend on its duty cycle D, the fraction of a cycle for which the signal is not at zero. In a well-designed inverter, the duty cycle will be adjusted when the DC input voltage goes up and down to maintain the nominal rms output voltage. If we use peak voltage Vp to mean the magnitude of the positive and negative voltages the signal goes to, then Vavg for an MSW is equal to Vp times D, and Vrms is equal to Vp times the square root of D.

The duty cycle for which an MSW will have the same rms to average ratio as a sine wave is 8 over pi squared, or 81%. For any duty cycle less than this, an average-responding meter will read a lower voltage than the inverter rms output, and for a duty cycle higher than this, the meter will read too high.

If your MSW inverter is putting out 120 volts rms and its duty cycle varies from 50% to 75%, the meter reading will vary from 94 volts to 115 volts. I avoid the problem by using a Radio Shack 22-174B true rms digital multimeter.

IF your washing machine is a conventional model with a common AC induction motor, waveform isn't the problem. Normal starting current for typical AC induction motors is usually 5 to 7 times the rated running current. Even though that current draw only lasts a fraction of a second, it's marginal for a 2.4 kw inverter's surge capacity. The trick of switching on other small loads (preferably resistive loads like incandescent bulbs) before starting the washer may help. Another area to check is your battery cables and connections The inverter pulls a huge amount of current to produce it's max surge output and even a little resistance in the battery circuit may cause the inverter to trip off. If you've got one of the fancy new electronic controlled washers with a D.C. motor, (so called energy saving or high efficiency models) then the waveform may be an issue and a pure sine wave might be needed.

I would not do this, you really need a pure sine wave inverter to guarantee the safety of your CPAP machine. At the price they are selling this device it could not be pure sine wave. 150W pure sine wave would be $70-$100.

Look I been using solar and wind power for the last 20 years and never used public utilitiy, run your inverter to a braker box and connect your pump to it donot forgfet to ground the box and the inverter. that is all what you need...remmber modified sine wave may effect the life of the pump if it is cheep it may be ok or you need to get true Sine wave.
