Identify the `total energy` payload of the MS51 status frame #64

I assume the Nuvoton MS51 on the WiFi dongle tracks the delivered energy and provides a total energy reading available at the Android app. The payload of the Soyosource inverter doesn't contain the value for sure.

Unanswered question: The maximum total energy is 0xFFFF (65535 * 0.1 = 6553.5 kWh). Is there a wrap-around?
