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 the cost of sizing and reducing genset time offgrid. Some of the good locations for sun do not need a generator ☺
