Is this pulse width modulation or pure sine wave output?

Enphase microinverters are designed to comply with IEEE 1547, Clauses 4.3.3 and 5.1.6. The spec for AC sine wave total harmonic distortion is 5% max (3% typical), measured IAW IEEE1547.1, Clause 5.11. This spec is further characterized in terms of Total "Rated" Current" Distortion (typically 2.0%), and Total "Demand" Current" Distortion (typically 1.3%).

Hi Roxann please note all solar inverters central or MIcro are pure sign wave inverters these are not to be confused with power inverters used to run appliances or such those do come in both standards you speak of

Hello, I purchaced to replace a cheape one that I had. Yes, It makes alot of noise, and bleeds over to FM radio's plugged in to it. I do not think it is a true full sine wave, I think it is a modified, wish is why it does that. Other than that, it works great. i lvoe it a great deal. Bob....

First of all be carefull - this is a modified Sine Wave Inverter. Not all 110 volt equipment will run on Modified Sine wave especially certain medical equipment. To be safe you should purchase a Pure Sine wave Inverter to get same as House line voltage. The unit has a built in breaker that if it gets too hot it will shut down. Manufacturers Operation guide does not show a maximum operating time. Depends on heat and Battery longevity

yes the 3500 Watt w Pure Sine Wave portable inverter is very quite. we use it during hunting season at the camp it works well. love it.

Maximum output RMS 20W, Frequency response 100HZ-13KHZ, Operating voltage 7.4V

The output is a modified sine wave, though I don't know what it looks like. I picture it being a pixellated version of the real thing, with an unknown number of successive approximations to the sinusoid (like, step functions rising to .3, .5, .7, 1.0, then down again). I have used the unit to feed into the external power supply to my MS Surface pro, and it worked fine for the last two summers on a fire lookout. As I remember, sometimes it appeared not be charging the batteries in the Surface, but then, later, they would be charged. That might have been a spurious interpretation by the power monitor in the computer. Anyway, it was an excellent solution for back-country use.

Great! now I need to decide on the proper inverter to use. The 1000 watt pure sine may be over-kill for just a TV/ DVD player and a couple 60 watt bulbs. Would a smaller watt inverter make more sense?

Not this one, it has a 50 Hz output and may damage your TV. Consider something such as a Xantrex or other brand of pure sine wave inverter.

It acts as a power conditioner, maybe not as good of one, but plugging it in will void the UPS's warranty. And i would also think it would affect the sine wave because of post processing of energy.

Hello, hhis pure sine wave inverter have input 12 VDC, output 110 VAC, the automatic switch we have con 110 vacío side

It's a modified sine wave inverter rated at 1350 watt continuous 1500 watt surge. Note however, that the battery inside the case is not sufficiently sized to run the inverter at it's full rated capacity for more than 10 or so minutes if that long.

Pure sine wave is the best way to go. I've had modified sine before and while they do work for most things, induction motors and microwaves don't put out full power and are noisier. I bought a 2800 watt Magnum Energy pure sine wave and have never looked back.

Frank, I don't know how it would respond to the modified sine wave but maybe there is an easier solution. From the nature of your question and this device I assume you are starting with a DC power source (12v car battery?), inverting it to 120v AC, and then converting it back to 48v DC with this power supply? If that is the case then you could skip a step and achieve greater efficiency by just using a DC voltage regulator that allows you to step up the voltage--Amazon sells them (eg. http://www.amazon.com/DROK-Converter-Voltage-Regulator-Charger/dp/B00BZR9PBW/ref=sr_1_1?ie=UTF8&qid;=1393267559&sr;=8-1&keywo;rds=12v+to+48v+converter).

the tripplite produces pulse modulated modified sine wave it is substantially cleaner than a low end modified inverter and should have no problem starting or running any 25 foot or less refrigerator

Not sure what a sine wave inverter is but the bulbs screw into any medium socket ( a typical house hold light socket)

It should always read 115V out (same as input). It's not a voltage regulator. It controls speed by PWM (Pulse Width Modulation) which means it changes the AC waveform. Look up PWM on Wikipedia.org if you'd like a more detailed explanation.

Hello data guy, This converter has matched the voltage and sine wave of what we normally get from the powercompany. Before purchasing, check with your power and insurance company about any liability on your part.One note of caution. My first try connecting two 250 watt panels was a disaster. The voltage was 60 vdc inputand the electronics couldn't handle it. Worked a short time then fried. Keep input dc voltage down.
