Review: From Home to Auto - Threw my old Sony powered subwoofer in the back of the ML430 with a new head unit drawing 225 rms i need a pure sign wave to keep the tunes sweet, this small unit works perfectly to supply 110 volts a/c to my subwoofer, helps punch up the bass substantially.
Review: GREAT UNIT! - It works better than a similar 500 WATT model. The 500 watt unit fan runs ALL THE TIME and it will NOT run the air pump to inflate an airbed! This one works flawlessly! Great Product. In fact I AM buying another one.This will be my third. I WANT SPARES for the future and I use one dedicated to my of grid fridge! God bless and be well!

## Questions & Answers

**Q: Does this inverter include a warranty other than the 30 days return to Amazon?**
A: Yes.it has a one year warranty.

**Q: I want to use this to power a 120 vac water transfer pump that draws 2.3 amps (276 watts). What size battery should I use?**
A: A battery bigger than 45Ah will be ok. The bigger, you can use for longer time.

**Q: I have a 500 watt modified sine wave inverter.  it will not run my 50 watt lcd tv. will this pure sine wave run it?**
A: This will be no problem to run LCD tv.

**Q: After 2 hours of running a small load, less than 100 watts the unit is beeping why? The battery deep cycle is not low voltage 12.72 volts**
A: Please tell us what exact load you are running?  The beeping  can be from low voltage alarming or overtemperature protection.  If the load you are running is freezer or similar kind of induction load which need high starting up power then this maybe a low voltage alarming as it will draw  high current in starting up and drop the battery voltage. The inverter Fan is running or not as beeping, please also tell us so as we can judge exactly what situation is this.  thank you!

### ⭐⭐⭐⭐ This IS a Sine Wave Inverter - Keep wires to battery short, or it will not work as expected..
*by J***S on October 25, 2023*

All of these kinds of inverters need a VERY good HIGH current connection to your battery. If your wires are too long or not a heavy enough gauge, then you end up with too much of a voltage drop in the wires and it's impossible for any inverter to supply the rated power. It will work for light loads, but then the demand gets higher, it will read the voltage drop as an under-voltage input as it should and shut down. You are taking 12 Volts and stepping it up to 120 Volts, and power is power, so if you only have 12 Volts and you want to get 300 Watts, you need 25Amps, and you need the 12 Volts AT THE INVERTER TERMINALS while it's pulling 25 Amps. If it drops down to 10 Volts due to the resistance of the wire, it's not going to work. If you need to supply the surge, then you need heavy enough wire to supply the ENTIRE Surge, This inverter has a surge capacity of 600 Watts, so you need heavy enough wire to supply 50 amps to this and keep the voltage drop down as low as possible, otherwise, when the surge happens, the voltage drop will cause an undervoltage condition. It should be noted that there is NO WAY that the included cigarette lighter cord could have a chance of supplying 50 Amps to this!! I wanted this in the back of my truck and use the auxiliary connection back there to run it, then feed the 120V back up into the cab. The auxiliary connector is fused at 50Amps, so I thought that would be sufficient, and while it could provide 50Amps, the gauge of wire built into the truck was not heavy enough to supply the power needed to end up with 12V at the inverter terminals while supplying the surge. I wanted to use this to run an ice machine in my truck, which needed 500 Watts for about 2 seconds to start the compressor, then 100 Watts while the compressor was running. So even though I was on a circuit rated at 50Amps, I could not keep the voltage at the inverter high enough during the start surge. I did not feel like running new wires, so what I did was put another battery in the back, and hooked up the inverter to that using the wires it came with (not the cigarette lighter plug, that is useless). With short wires connected to the battery it was able to start and run the compressor with no problems. Since it's only the starting surge that really needs the battery, I was then able to use my original connection to keep the other battery charged. This second battery ends up being nice because not only does it supply the start surge, but it allows me to run the inverter when the engine is not running without risk of draining the battery so much, I can't start the vehicle. Unfortunately, this unit was giving me a warning beep while my compressor was running, so I thought I better go to the next size up, which has a capacity of 600 Watts and as 1200Watt surge, and it didn't cost that much more. That one came with heavier cables, I bet if I put the heavier cables on this one, it would have been fine. Edit: I was reading other reviews about this and some claim this is not a sine wave inverter, so I thought I don't want to give a 4 star review if this advertised as Pure Sine Wave and it is not, SO I went to verify this claim on my own, since I am an electronics engineer with a bachelor's degree and over 3 decades of experience, and of course I have many oscilloscopes, I am more than qualified to make this test. So I used a soldering iron as a load, since it is mostly a resistive load, and hooked up the test, using a fully charged battery and connecting only the battery to the inverter, and then plugging in the soldering iron, and hooking up my x10 probe to the line output, and of course hooking up ground to neutral, which I can do because this is entirely floating as the battery has no connection to ground, and I was astonished then right there on my Oscilloscope screen was an undeniable SINE WAVE!!! It's NOT a modified sine wave at all, it's a pretty good PURE SINE WAVE. It has a few minor glitches in it as you can see in my photo, but for the price, it's pretty darn good, and those glitches can't possibly make any difference at all, especially in anything like a computer that does not directly use the AC anyway, it's all rectified and regulated to DC so the exact shape of the sine wave could not ever make any difference at all, and in fact the sine wave provided by this is CLEANER than the sine wave provided by my utility company! There is a simple way that an oscilloscope can show what looks a square wave... when the input is a sine wave... if you forget to switch the probe to x10 then in fact since you would be then exceeding the voltage capacity of the oscilloscope, you will get some kind of square wave on your display... but there is NO Way to make a scope display a sine wave when there isn't one.
