My battery is discharging to the grid, not the usual few watts, but a HUGE 1.6KG. Everything is turned off to tell it to do this so there is no reason. 
Whats going on! This could cost me money. I got the battery to save mony not send it to the grid at a loss!
Now its importing from the grid instead of using the battery?
GazzaGreen Check inverter card, settings, look at all the timed charges etc. If in doubt you can factory reset which will just leave eco mode on.
Seems to be working again now.... whew
The figures at the top are a random point in time, roughly every 5 minutes.
Seconds later it could be opposite way around.
Best to look at the totals, not the point in time.
Or use the app in home mode and see it every ten seconds.
Or look at your smart meter IHD if need be.
Not saying there isn’t an issue, but the “live” data there isn’t good enough to make judgements on.
