@sleepy62 I want a battery like that! 😁 With an additional car and a climate a bit colder than ours, usage is really not that extraordinary - and yes, 1 kW sustained usage with a couple of large fish tanks is probably to be expected. We're currently looking to add a 10 kWh battery to our small (7 kWp) solar system as well as a 6 kW hybrid inverter, and we're debating whether to increase both solar and inverter capacity, or add more battery capacity instead (the budget is fixed, so something has to give). Danish power distribution adds tariffs to peak usage times, so we have 4 hours in the morning and another 4 hours around dinner time where electricity is significantly more expensive, while being very cheap during off-peak hours at night. I don't think we will get to a point where we run entirely on our own electricity, not even in the summer, but it would be nice to be able to operate on battery power during peak hours, and then charge during off-peak hours from either cheap grid electricity or our own solar panels. We use 3-4 kWh during the peak usage hours in winter, which means that a 10 kWh battery is slightly smaller than needed, so right now I thing we are going with a bigger battery and live with our small solar system - it can easily charge the battery in the summer anyway.
