The Pylontech documentation is silent on the SCS parameter:
Default is on. Must it be on? I will update it based on this answer.
SCS only has effect on the tail current measurement used by MPPTs to end absorption phase - when the MPPTs use their internal charge cycle.
If an ESS or battery bank is controlling MPPT charge cycle via 'external control' then SCS would have no effect.
