All has been going well for several months since the breaker was removed to my battery (last post).
In these sunny times, I noticed that theres a lot of sunshine still available after the discharge period has expired - or the battery has hit its FD minimum.
Tonight, the battery discharged back to the grid and reached its FD minimum of 29% by about 6pm, and stopped discharging. But the panels are still producing a lot of power (capped at 5kWh by the inverter).
Rather than sending this power to the grid, the system appears to send it to the battery first, even though the FD period is still active.
Is there a way to 'restart the FD' as the FD minimum may have ben reached by the batter has gone back to charging, and as I type this its up to 63% - so 34% of the capacity should have been dumped.
In all honesty i’m surprised that when the Force Discharge period is still active with an FDSoC set, it would charge the battery once it gets to FDSoC.
The default workmode it returns to is Self Use afterwards so perhaps it is defaulting to that once it meets the FDSoC condition… ? - i’d be inclined to check your firmware is at the latest versions as depending on inverter model the early versions of Force Discharge had a few bugs.

Heres my settings.
And here's the behaviour.
But on a really sunny day (three days ago), where the solar system is running full tilt at FD start time, the solar panels go straight to the grid for over 90 minutes until the sun drops a bit, the FD time seems to be recognised and so discharge starts to happen even though the solar is available to provide all the FD power ?
That tends to suggest that even though the solar can continue to provide export to the grid, the batteries tsrat doing it and power is effectively lost as the solar panels cant charge the batteries and cant send to the grid ?
Surely the most efficient way would be for the panels power to always go to the grid during discharge time and only do the batteries as a topup when the panels cant produce enough ?
