NOT enough information !! The 3 KW inverter sine wave or MSW; The RCD or GFI may easily trip if the inverter is MSW-- remember that just 30 milliamps are enough for the tripping.
Also. if there is a differential inductance or a loose cable that may generate a voltage drop near the GFI, then tripping.
