Excess production

This is more of a general interest question , if a solar system produced 4 kw daily and the consumption is only 3 kw then what happens to the extra produced . I know some is used on Equipment , Charge Controllers , Inverters Etc and some natural loss from the batteries but i dont think that would account for 25% in my case a KW each day , the batteries are AGM and new , the equipment is Victron and also new , all the settings and operation of the Charge Controller is correct and as i would expect , im taking these figures from Victrons VRM Historical Data which shows the daily production and Consumption .

It is simply unused.

Then am i right in thinking that the most that can be produced the following day couldn't be more than the amount consumed the previous day plus natural battery loss and the loss through equipment efficiency

And the energy you use that day of course! This time of year it is hard to use it all offgrid if you are sized for winter!
 It is the cost of sizing and reducing genset time offgrid. Some of the good locations for sun do not need a generator ☺
