EG4 WallMount AW + Schneider XW Pro: External BMS or Custom/2-Stage?

DeadSparky

I have an EG4 WallMount All Weather 51.2 V / 280 Ah battery on a Schneider XW Pro 6848 with InsightLocal.

 

Current XW battery settings:

Battery Type: Custom
Charge Cycle: 2 Stage
SOC Control Enable: Enabled
Capacity: 280 Ah
Bulk/Boost: 55.2 V
Absorb: 55.3 V
Low SOC Cut Out: 15%
High SOC Cut Out: 99%

But the XW status page says:

Battery Control Mode: Voltage Control

Question: For EG4 WallMount AW + Schneider XW Pro, should this be left as Custom + 2 Stage + SOC Control Enabled, or changed to Li-Ion + External BMS + SOC Control Enabled?

Also: is P03-SCH normal on older EG4 firmware? Current docs seem to say Schneider is P04-SCH, but mine says P03-SCH and the BMS data is clearly coming through.

External BMS is available in the Charge Cycle dropdown. Li-Ion is available in Battery Type.

Battery screen:

RS485: P03-SCH
CAN: P07-LUX
BMS: Z02T13
LCD: V1.1.0
SOC: ~70%
Voltage: ~53.47 V
Cells: 3.339–3.342 V
Temps: 28–29 °C

InsightLocal sees the BMS:

Battery Type: SEMB_BMS
Associated to: House Battery Bank 1
SOC/SOH/voltage/current/temp all visible
Charge permitted: 1
Discharge permitted: 1
No BMS faults/warnings

EG4 should be guiding you on how to set this up!  What firmware is XWP ?
