I think your figures speak for themselves of how good hybrid inverters have now become. :mrgreen:
Yes very pleased! It's nice to go without grid especially with global events currently.

I am also looking into why I have any import at all, I think it might be a reactive power bug with meter.
You'll always have some power import. When a load switches on it takes a few seconds for the inverter to react and start discharging the batteries more heavily. Steam irons are particularly bad for this. And I've noticed my oven on "ECO" mode switches the heating element on and off more frequently than normal mode. Also there'll be times when your power demand goes above your inverter capacity.

That your grid usage is so low shows that your inverter reacts quicker than those sold a few years ago...

You will always have some import due to the response times of your inverter and some go into standby if your import is less than 100w.

I typically manage a peak rate import of 3kWh a month but my inverter is set to never go into standby and I have to set an offset so I am constantly exporting 10w in order to get my smart meter to generally read zero import. :cry:

When I had my Economy 7 (non smart) meter I could import a constant 20w without it registering any import. :D

If you have a Tesla Powerwall and a certain model of smart meter it can be very bad indeed. :shock:

Yes I'm aware there is always some import but the logs look strange to me - especially bsince I've had several days of identical imports which makes me wonder.
