    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: Pure sine wave power inverter applications

    The pure sine wave power inverter can provide clean, stable and high quality AC power, ideal for powering all kinds of electrical appliances including sensitive electronics like air conditioner, refrigerator etc., and resistive electronics, such as bulbs, TV, fans and etc.

    Great addition for RV
    Just before I purchase this inverter I had a loud one with less power that I had to shut down at night. Very impressed with this 3000W pure sine wave inverter. I've been camping for 10 years, and delighted that such a thing exists.

    Best on the market
    The reason is that this is not some cheap knock-off, but a Made-in-America product.  Look at the range of products this company makes and you will realise that their inverters are better than average.  I've selected a 24v dc to 220v ac @ 50 hz to run the ac requirements of a yacht travelling the world so IT HAS TO BE RELIABLE in all climates. 2 fridges, microwave, kettle, Insta-Pot pressure cooker - it can can handle them.  Good luck if you risk buying cheap instead of buying reliability

    An excellent value power inverter
    It performed extremely well in a very hot and humid climate. It easily handled a mini fridge, 120V LED light bulb on a dimmer switch and charging 12V power tool batteries. I was then careful to keep in in shade.

    A great value for my money
    Don't hesitate to buy this pure sine wave inverter! Great for RV or van life too. It is easy to set up and use. This is the most joyful purchase I have made on Inverter! It's definitely a great value for my money.
