    Note: The wiring of 48V inverter is similar to the 24V inverter, and the batteries are connected in series.

    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: How to judge whether the power inverter is appropriate?

    First of all, it need to consider efficiency of conversion. Because the inverter itself has a certain power consumption characteristics, part of the current will be always lost when DC is inverted to AC. Therefore, the high or low efficiency of conversion in this process has also become one of the standards that power inverter is good or bad.

    Secondly, take into account the quality of inverter's output AC power. Good power inverters output high quality AC power after invertering. And good stability is not only beneficial to the service efficiency of the inverter, but also beneficial to the safety of users' lives and property. What’s more, the service life of power inverter is relatively longer. However, for the poor quality of the inverter, the output power is unstable, which may cause safety hazards and shorten its service life.

    In addition, when purchasing a power inverter, it also needs to consider the DC component contained in the output AC, which is called ripple voltage. It will be completely filtered in the filter circuit of the good inverter.

    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.

    Power to my fridge
    I used this 800 watt pure sine wave inverter as a backup power supply for the fridge, it works better than I thought, and the price is right. I've been using it for three months now without any problems.

    Is the inverter designed to charge the battery same time while on DC input mode?
    Is the inverter designed to charge the battery same time while on DC input mode? Can this be done with an external charge you sent me? Inverter Charger does not seem to be charging batteries fully.

    ATO Responded
    No, the inverter is designed in bypass priority mode. When you select DC input mode, most of the battery output current is used for the load, which will not have enough power to charge the battery.
    We recommend that you set the inverter working mode to the initial state - bypass priority mode. When you want to charge the battery, pls don't use the inverter to carry the load.
    You could also use the external charge we sent to charge the battery, but it's an AC charger.
    Great value and works great!
    I bought this 800w pure sine wave inverter specifically to power a small portable ice maker which I take when boating or traveling in our RV. So far loving this inverter. True sine wave.

    I am interested in your power inverter
    I am interested in purchasing the zpx-5000w inverter, 48v dc input. Can these inverters be frequency sync'd so I could add 2 in parallel?
