    Protection Functions & Applications

    pure sine wave power inverter protections

    Pure sine wave power inverter applications

    • Reverse Polarity Protection
      Auto protection when input positive and negative polarities are reversely connected – The fuse blown out.
    • Short Circuit Protection
      Automatically self-protect when short circuit occurs – Red LED light ON.
    • Low Voltage Protection
      Automatically protect when in low voltage – Alarm first, the voltage continuously reduces, the red light is on and the inverter shuts down.
    • Over Voltage Protection
      Automatically protect when in high voltage – Red LED light is on, and the inverter automatically shuts down.
    • Over Temperature Protection
      Automatically self-protect when at high temperature – Alarm first, the temperature continuously rises, the red light is on and the inverter shuts down.
    • Overload Protection
      Automatic self-protection when there is overload – Red LED light is on and the inverter automatically shuts down.

    Tips: Differences between pure sine wave inverter and modified sine wave inverter

    The waveforms of the inverter are mainly divided into two categories, one is a sine wave inverter (ie, a pure sine wave inverter), and the other is a square wave inverter.

    The sine wave inverter outputs sine wave AC power that is as good as the grid we use every day, because it does not have electromagnetic pollution in the grid. But the square wave inverter outputs a square wave alternating current with poor quality. And its positive maximum to negative maximum value generates almost at the same time, thus causing severe instability to the load and the inverter itself. At the same time, its load capacity is poor, only 40-60% of the rated load, and it cannot carry inductive loads. If the load is too large, the third harmonic component contained in the square-wave current will increase the capacitive current flowing into the load. In severe cases, the load filter capacitor will be damaged.

    In view of the above shortcomings, a modified sine wave inverter emerged in recent years. The output waveform has a time interval from the maximum value in the positive direction to the negative value in the negative direction. The use effect is improved. But the waveform of the modified sine wave is still composed of broken lines, which still belongs to the square wave category. The continuity is not good, and there is a dead zone.

    Modified sine wave inverters generally use non-isolated coupling circuits, while pure sine wave inverters adopt isolated coupling circuit designs. The price is also very different. Pure sine wave inverter is a little expensive than modified sine wave inverters.

    In this video, ATO makes a simple test on the input and output voltage of 1000W 24 DC to 220V AC pure sine wave power inverter. And, this power inverter is used to power a cell phone and a fan which work normally.

    How to Diagnose Inverter Problems and Repair
    An inverter is a power conversion device. The basic working principle of an inverter is to convert direct current into high-frequency, high-voltage alternating current through pulse width modulation (PWM) technology. The core part of the inverter is a PWM integrated controller, which is responsible for generating PWM signals and converting DC power to AC power through MOS switching tubes. A blown fuse is one of the most common reasons why an inverter has no output. This video will show you how to perform a simple diagnosis of a failed inverter and how to fix the problems.

    Wonderful 24V 2000W power inverter!
    I bought this ATO 2kW pure sine wave inverter specifically to work with my ebike battery charger for off grid ebiking. The inverter is connected to my truck camper battery. I was really surprised for the quality of the inverter!

    Powerful pure sine wave power inverter
    Now that this pure sine wave power inverter is installed in my conversion van, it's a home away from home. I can use my refrigerator, plug in my rice cooker and popcorn maker. It has a powerful 2000 watts of power.

    So far so good
    It was able to power a few fans, few lights, and the fridge off of it without overload. We secured it on a horizontal space, and pure sine wave power inverter works perfectly. So far I'm happy with my purchase.

    12V2000W pure sine wave inverter fan volume in decibels
    Hello, with your 12V 2000 watt pure sine wave inverter, is the fan ever completely silent or is it always spinning? May I ask how loud the fan is in dB? Thank you.
    From: Mikes | Date: 26/08/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    The fan starts automatically when the temperature reaches 45 degrees, and the noise level is approx 65dB or less.
    Question for 2000W pure sine wave inverter
    Would the 2000W pure sine wave inverter be appropriate for input of 42V DC?
    From: Anderson F | Date: 16/05/2019
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, just select 48V DC for input, so the the inverter can accept 40 - 61V DC voltage in input.
    2000W power inverter works wonderfully
    I am currently using this 2000W power inverter in my 2015 Toyota Prius. It works wonderfully. I am getting ready for hurricane season because last year (2018) we were out of power for 8 long days, and I don't want that to have to sleep in this Florida heat with no A.C or a working fridge again.
