    Hello cordially

    I am looking for an inverter that works directly from photovoltaic panels and has a pure sine wave of AC current at the output. There is such a thing?

    I only found an inverter with a modified sine wave at the output.

    How would this inverter provide stable power at the output of the system without a buffer in the form of batteries? One cloud and you're done.

    You can at most connect this to a heater, which is indifferent to the stability of the power supply.

    SinusPro version S, but as they write; it will work until the first cloud, or until the power consumed exceeds the yield of the panels.

    I realize that until the "first cloud" it will work. I need something in the range of 150-280V at the input. If I give 7 panels x 39.1V = ~278V. I will try to regulate the fluctuations with an automatic AVR Power consumption is max 200W (emergency situations). Only SinusPro S is suitable for this?
    I'll tell you this: the inverter must have a sine wave because it can be used in emergency situations to maintain voltage, for example, a refrigerator (I know that only during the day and in sufficient weather), on a daily basis will be connected to a 1.5kW heater and therefore there can be no battery.

    This is not a cheap subject ,closes in the amount of more than a thousand
    Mr. Wojtek has a wide range of devices .
    I am still looking for "luck" on the Internet ;) .
    There is also something like this from these "rectangular sine wave"
    Link .

    500PLN regulator with DC output .
    800PLN rectangular sine .
    True sine over a thousand, that's why I'm pinching myself a little .
    Contact very good , but I will still look .

Topic summary

The discussion revolves around the search for a pure sine wave inverter that can operate directly from photovoltaic panels without the need for batteries. The user expresses a need for an inverter that can handle input voltages between 150-280V, specifically mentioning a configuration of seven panels producing approximately 278V. Responses highlight concerns about the stability of power output during variable weather conditions, suggesting that such inverters may only be suitable for specific applications like heating. The SinusPro S model is mentioned as a potential option, but users note that it may not perform reliably under all conditions. Other suggestions include various devices available online, with price points exceeding a thousand PLN for true sine wave inverters.
