SCU Battery Container

Configuration

In the SCU interface:

Go to "Maintenance"
Go to "Comm Settings"
Go to "PCS"
Under "BMS: Number of devices" -> Set this to the amount of batteries / BMS systems that are connected.

GRES uses the same SCU interface path, but configure based on battery rooms (up to 4 groups):

Go to "Maintenance" → "Comm Settings" → "PCS"
Set "BMS: Number of devices" to your battery room count (1-4 for GRES-300-200)
Ensure PCS remote control is enabled for curtailment
Modbus address: Default 1 (matches driver DEFAULT_BUS_ADDRESS: 1)
