With 3 hours of free power, a 15kW inverter and a 42kWh battery, I could almost do away with my solar panels and just survive of free grid power. I do have a 15kW solar panel set up, but I get very little from selling anything back to the grid.

I have a 12 kW inverter (single phase) and 48 kWh battery. In Australia, 9 months of the year my 16 kW of solar fills the battery and covers all needs including cooking, heating and charging the EV.

In winter, I’ve been using Ovo’s 3 hours free for about a year now and that ensures the battery is filled up daily. My electricity bill returns a credit every month since I got the battery a year ago.

		I was trying to understand how to do this, and I formed the opinion that most of the battery providers don’t really allow the degree of ‘on/off’ or ‘charge/discharge’ customisation as might be necessary to make this work? Or was I fooled by the packaged products that are aiming to turn me and my battery and panels into a residential power plant at the whim of the energy company?

There is a 24KWh/day fair use

Grid power is already cheap. Making things free actually makes people use more power. Its called the rebound effect.
