Please help me understand the readings

I just successfully installed my Marstek B2500 (HMJ-3) battery and have few questions from my first observations:

I see several things I don't understand here and wonder if other experience this too:

• Why is the battery output not maxed out? I configured the limit to 800W and currently the load that is reported from the Shelly is higher. Could that be a temperature limitation of the inverter (currently at 62°C)?
• Why does the battery not use its two outputs synchronously but outputs more power via output 2 than output 1?
• I notice a pretty large discrepancy between the reportings of the battery and the inverter. Notably I would have expected that the battery outputs should be the same es the inverter inputs (accepting a few % tolerance). Also the AC-out reported by the inverter is higher than the Output of the battery, which doesn't make sense to me. Or am I interpreting the values wrong?

Here's another screenshot that shows the same behavior combined with the update values being only 6 seconds apart.
