    How to Reduce the standby current for Low Frequency Power Jack inverters

    I have a 10,000watt power jack 48v LF 120/220vac split phase power inverter with high standby current . I don't want to use it in power save mode.
    I want to use it in normal mode and still have a low standby current draw.
    Can I reduce the standby current significantly by installing an inductor inside and if yes where exactly should I place it and does the power jack comes with a built in inductor which I would have to bypass?

    Here is a link for the inverter:

    Why do you think adding an inductor somewhere, would reduce the idle consumption ?

    And what is your "standby" current? My house, pumps, water filtration and all, comes up to about 200w baseline load. That's not standby, any baseline loads will have the inverter running, not in idle/standby/search mode.

    What a marketing coup it would be, to include a $20 inductor in a product and be able to claim a 50% lower self-consumption power rating. Worth at least a $40 markup.

      I rebuild a power jack inverter in the past using an aftermarket board that I bought from aliexpress and you have to use the same inductor above with the motherboard and it allows the standby current to reduce by a lot. So I am wondering if the same thing can be applied to the power jack boards.

        If the inverter is powering some loads for example exactly 300watt worth of loads I am using and at normal mode draws 3 amps just to standby. If I use a wattage meter and check I would be in fact drawing the 300watt worth of loads plus the 3 amps that the inverter takes to operate or is it that once the inverter is powering some loads then that 3 amps would be auto decrease as it would not be in standby mode currently.
