How low can you go...Daily, Weekly, Monthly, Whatever... electricity grid import

574 Posts


It has been the first week of the year when I have had little or no import from the grid so I am creating this thread so we can brag about how little energy we import in a week. I was surprised at this low figure as we were not deliberately time shifting energy usage. It has been a normal week with cooking, baking , washing, dishwasher and showering (I did convince my better half to use the power shower instead of the 10 kW electric one as there was ample hot water heated by the immersion).
I think it will be difficult to get down to zero because of the inverter not being fast enough when certain electric appliances kick in and out causing some minor import, early morning toaster and kettle at the same time will require some import... so who will be the first to Zero ?

The leccy shower is what kills it for me, its running 5 times a day on a normal day, so unless I can convince the family to shower when the sun is out (tried and failed) then it's not gonna happen.
I suppose the silver lining is that it's 2kw a day from an average usage of 30kwh a day (not sure why it's so high, it's usually 20-25kwh a day) so the solar +batts is working well.
Just need to fit hot water tank and ditch the leccy showers

How much did your battery setup cost ?
If you don't mind me asking.
