Is the inverter true sine wave?

No, the inverter is Modifyed, we can supply a pure syne wave for an additional $150.00 Thanks, OG Solar

It is my understanding that it is NOT a pure sine wave. I do run a HDTV and Blu Ray player with it and have had no issues

The SMART1500LCDT has a PWM sine wave (Pulse-width modulation), not a pure sine wave. However, Tripp Lite carries many other 1500VA UPSs with a pure sine wave output. Also, please know that not all computers and electronics require a pure sine wave.

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

Be very careful. Most gensets will produce a full wave AC but they don't have much tolerance for big surges. Most cheaper inverters DON"T do full wave. The Vagabond does (full wave AC).

The "pure sine wave" inverter can help running some things and eliminate a sound "Buzz" that can come from the cheaper "modified sine wave" inverters running radios & such. However, I'm not sure for a laptop that it will make that big a difference since the power is converted back to DC anyway (where it almost seems funny to take DC power, change it to AC just to go back to DC).

Pure sine wave will always be the default recommendation, especially for electronics. However there is generally a big cost hit with pure sine wave compared to simulated sine wave. For a unit like a power supply which is quite robust in design, when talking about the quality of power input, a simulated sine wave UPS would be acceptable to use. It is certainly much better than exposing the PSU & your PC to power brownouts.

No. You want a Grid Tie Inverter, search for that keyword. This only converts DC to PURE SINE A/C current. Pure Sine is the ONLY way to power sensitive electrnics like microwaves, TV, computer, etc.. Pretty much everything made with technology developed after the 70's. A/C motors can run on modified but they run cleaner and cooler on Pure Sine. Pure Sine is what you get from the mains. Modified sine is 1970's tech and good for things from that era, unless you like to buy whatever you plug in again and again and again and simply LOVE the sound of a constant buzz from whatever your using. IMO, Pure Sine or don't bother. But you want Grid Tie Plug and Play. I have them and they last and work well as long as the power is on, this one however is for when the power is OFF and you have batteries but need to run A/C appliances.

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

If you use a modified sine inverter with an led tv you will not like your picture. You should use a pure sine. Also your tv will last longer on a pure sine.Joe

It's not a "Pure Sine Wave" - those are expensive. This one is a "Modified Sine Wave" - a square wave in other words. it didn't interfere with my car radio, and didn't cause any radio noise in a small tabletop 120V radio that I ran out of this inverter.

As another said, it's because the inverter puts out a "Modified sine wave" where it's power isn't exactly the same as house power. If you have an electrical workers oscilloscope, you'd see the house power curve up to the max and drop down in a curve, any power inverters that aren't labeled "True sine wave" just put out pulses of power with it instantly jumping to max, staying on max for a few milliseconds, then turning off (with no curves). I don't know fully why the "buzzing" comes thru, but it is the inverters power (and I've seen that explained in power inverter manuals).

All generators Champion makes use a true sine wave. It does not use square or modified sine waves. When it has a lot of THD those waves grow erratic spikes on them but they still maintain their waveform

No this is a modified sine wave inverter----we have had trouble with this inverter being able to work with one type of cordless tool charger-----so we purchased two different brands of pure sine wave inverters to see if this would in fact eliminate our problem-----it did not so we went back to this inverter and have not had any other issues with it not running any tools with the exception of the one----and that was solved by putting 12 V vehicle chargers in all the service trucks-----we run over 140 of these and they have been bullet proof---1 failure in 140 plus units in service

The wattage output on our pure sine wave inverters is not divided between the AC outlets, so you can pull the full wattage from one outlet. However, a 900 watt coffee maker will require a larger inverter to meet the coffee maker's heating preparation.
