In two EVC parallel system, do I need to do the settings for each EVC?

Do the APP setting on primary charger, no need to do setting on secondary charger.
1. Enable Parallel function in advanced setting.
2. Choose power allocation ratio, the default is 1:1, and supported ratio is 1:1, 1:2, 2:1.
This feature is to allocate the PV energy and remaining load capacity for the two
charger if user needs
3. Set the main breaker value as needed on primary charger.
