    Are you monitoring at the inverter connection BEFORE it "sees" the house or other loads ??
    monitoring right as it comes into electrical panel, right before the respective breakers

    Yeah, AC wattage is what display is showing me.
    It is kind of strange to have the energy monitor showing less energy output then the #1 inverter and more energy output on the #2 inverter.

    I know the wattage is a calculation of the amps x the voltage so maybe the voltage being measured is different on at the energy monitor then the inverter. If you have a way to measure the amps and volts that the monitor is measuring maybe you can determine if the wattage value is correct.

    The measuring monitors may also be mixed up or configured wrong.

    Can you provide us with any pictures or wiring diagram of your system?

    started a topic energy monitor not matching output of inverters ??

    energy monitor not matching output of inverters ??

    Just installed wifi eyedro energy monitor in my panel - includes 2 clamp on sensors.

    I have 2 inverters, each with 2 non neutral wires and 1 neutral for AC output.

    I played around with different combos clamping each sensor around a pair of non neutral wires (trying to get the right phases together) and ended up with something close.

    BUT it's not matching identically with inverter display.

    Ex: Inverter 1 display says 841 W, inverter 2 says 603 W, but my energy monitor is showing 778 and 783.

    Do you think I have something swapped? Or will the current sensors never match that closely to inverter displays?

    Thanks in advance.
Working...
