Sungrow DTSU666-20 - Displayed Functionality

From the displayed interface, the electrical parameter and energy data are all primary side data (that is, the
multiplied by current and voltage ratios). The energy measuring value will be displayed seven bits, with the
displaying range from 0.00kWh to 9999999MWh.
