I have just had a smart meter installed and looking at the app it is showing I am importing power from the grid, not much 0.04kws, even when I am exporting more than 13 kw of solar back into the grid. I do not have any large equipment running, just the normal household items. I have had home with smart meters before and have never had a import reading while exporting solar. Is this a faulty or incorrectly installed meter. Thank you.
