So where is that 54 going???

Ignore it - it's not really doing that. In general you can ignore small numbers anywhere (or at least not given them any credit). If you are not sure, check it out whilst watching your smart meter display.
I could list all the reasons small numbers can be misleading but it's a long list with lots of caveats. Suffice to say that current measurement by the inverter is not 100% accurate and many of the numbers you see therefore have a margin of error.
There is normally some small grid load or export, caused by the inverter playing catchup with moving targets of solar and load.
Inverter takes time to detect, calculate and adjust its output to balance it.
New firmware soon is 10x faster, so the grid will more accuratly be kept at 0W
TheDragon (GivEnergy) I agree the new firmware is much quicker to achieve balance. However (from smart meter observations alone) it appears that the individual import/export swings are now bigger. There are fewer swing cycles taking place before balance is achieved (hence the quicker reaction time) but the swings that do occur now appear to be of the order of plus or minus 90-240W rather than the 40-60W I was seeing previously. A quicker, courser correction rather than a slower, finer correction if you will. I would be interested to know if you are seeing the same. This apparently new behaviour is particularly noticeable to me when there is intermittent cloud cover with the sun going in and out in rapid succession. The net effect remains peanuts in the grand scheme of things and is of no great concern to me. Just a different way of achieving the same thing.
