Too early cutoff when load is low

During years we optimized pwr consumption of our home, idle mode at night is around 250W-350W ish. Last night was the first our new Multigrid / LG RESU 6.5 combo was running the home by battery. Nice feeling btw.
However although minimum SOC is set to 20% system switched back from inverter to grid at 49% SOC.
My first guess - this is related to the cutoff voltage which is relatively high for small loads. If so how can I change this behavior?

Hi, Lower the low voltage cutoff values.

Txs for confirming, to better understand sensitivity of parameters I'll try now

0.005 C= 50.80 V

0.25 C= 49.90 V

0.7 C= 49.20 V

2 C= 48.00 V
