Exporting to grid despite <100% battery SOC
I noticed today that although the PV production was good, my battery charging wasn’t always taking advantage of the full PV power and instead the system was exporting to the grid. I’m aware that low temperatures can cause a lower power charge but the temperature wasn’t too low today (see screenshot). There’s a weird (not a smooth curve) behaviour for the battery charge (see circled region). I took snapshots at 10:05 and 11:45 where you can see im Exporting to the grid despite not having 100% SOC. Is there perhaps a safety feature at high SOC to limit the power (eg at 11:45)? Much like EVs? But then again what’s the reason for the low charge at 10:05 when the SOC is 48%?
any ideas?

I’ve just noticed with latest firmware on the 3.6ECCO - high Soc charge throttling now starting at 70%. This is becoming quite annoying!
