I have an off-grid setup with 2 EG4 18kpv Inverters in parallel.  I also have 2 banks of 6 EG4 LL Batteries for a total of 12 or about 60kw of battery.  When I view the Inverter monitors web they give me confusing and differing data for the BMS.  My Parent Inverter says

BMS Limit Charge: 300 A
BMS Limit Discharge: 600 A

While my Child inverter shows

BMS Limit Charge: 66 A
BMS Limit Discharge: 66 A

When I view the same screen on the App it shows those same numbers but the Parent Inverter also says:

Batt Parallel Num: 6
Batt Capacity: 600Ah

While the Child Inverters states:

Batt Parallel Num: 0
Batt Capacity: 0Ah

I must have a setting wrong somewhere but can't figure this out.

Are you sharing all 12 batteries with both inverters? Or does each inverter have its own battery bank?
