Its pretty confusing so I'm just going to post my settings below and explain how it works.
Most of my output is on "Load" I have a geyser and plug on "non essential".
The system one screen I'm sure you are OK with at this point:

The system 2 screen is as follows:

Based on above during non loadshedding both "load" and "non essentials" are powered by a blend of solar, battery and grid until the battery SOC reaches my system1 preset. After that they will both power from solar and grid.
If there is loadshedding then "non essentials" is off and only "Load" is powered by solar and battery.
The 0w in "inverter power limiter" prevents power from going past the CT coil in this specific config. It has a different purpose in other configurations.
"Priority load" means "Load" gets PV power before the battery or grid (this seems to be best in most scenarios)
To confuse you further there is another input/output called aux/generator. Apparently this is smarter and has more adjustability but info is scarce and I don't use it.
