Solar being sent to grid rather than charging batteries

Set your self use mode between 0530-2330, this is to use your battery/s. Then during IOG cheap rate at night, charge your battery/s and car etc at the off peak rate.
During the day, adjust (grid feed in power limit) accordingly. If the sun is powerful say 4.2kw, maybe send 2.5Kw to the grid and the remainder will feed the house and top up the battery/s.
It looks like you’re currently sending more to the grid than is being supplied and hence your batteries low. Or, you didn’t have your self use mode to NOT use the battery whilst the car is charging, so it has used all of your battery to charge the car, as well as from the grid.
Also, I’ve noticed your battery is at 3%, you should limit its lower limit to about 10-15%, mine won’t allow the batteries to drain below 12%. This ensures you don’t damage your batteries by allowing them to discharge too far.

Octopus Go cheap chsrge rate is between 0030 hrs and 0530 hours.
Type into You Tube (how to change solis force charge times). There will be a video. I managed to set my parents to charge between these hours.

This is usually just a settings issue rather than a fault. On Solis systems, if it’s in feed-in/export priority, it will send power to the grid before charging the battery, whereas self-use mode does the opposite (solar → home → battery → grid) . Check your inverter mode and battery priority settings, switching to self-use or battery-first should fix it so your solar charges the battery before exporting, more details here: Commercial solar panels UK
