Flashing green light on battery

There may be a very simple explanation. Why is the round green light between 'routes' to House, Battery & Grid flashing most of the time.? Assuming generated electricity is going to the grid. At present Good Energy pay my Feed In Tariff monies. .Battery is full. With the sun as it is my solar panels must be generating constantly.
Wouldn't know what to look for if I looked at Inverter in loft. Although I can access info from my online GivEnergy portal am not able to interpret activity whether working properly or not?

Flashing Green: The system is in waiting mode (waiting for solar power generation to begin, which is completely normal at night or on dark days).

Flashing Red and Green: The system is currently undergoing a firmware update.

Solid/Flashing Yellow or Amber: There is a communication issue (such as lost Wi-Fi connection or a portal offline state).

Solid or Flashing Red: The system has detected a fault and entered a protection state.

MERLIN Although I can access info from my online GivEnergy portal am not able to interpret activity whether working properly or not?

Why don't you post a screen capture of the your portal dashboard, in the day when the sun is out, and the Inverter is flashing green. Then others here will be better able to advise you.
