I'm in Canberra and this worries me, i wish i'd known about this before i bought a L9 in January, i would have gone elsewhere.
Do you guys realise that it is battery preservation issue? Best practice recommends that lithium batteries are cycled within certain limits to preserve better lifespan. Cycling from 10-100% gives it a certain lifespan which I think is what FoxESS estimates, ie 6000 cycles before dropping to 70% efficiency. Of course many other factors impact upon its lifespan such as temperature and how fast the battery is charged or discharged etc. Dropping to 0% battery will bring on faster deterioration. Ideal recommendation is actually to cycle between 20-80%.

I was suggesting that you can only access 90% of capacity because the last 10% is to protect health of battery.
