electric energy. It is made by a simple semiconductor PN junction that the major
output characteristic is that there's only one maximum power point (MPP) at
certain sunlight intensity. The PV inverter is designed to track this point to
harvest maximum energy that is generated by the PV array.
Introduction of SAS interface
1. CH1 status bar: displays the output status of power channel 1.
2. CH2 status bar: displays the output status of power channel 2.
3. CH1/CH2: channel selection, Channel 1 or Channel 2.
4. SAS edit button. The functions are described as follows.


5. PV analog output in Userdefined mode. Support setting Voc, Vmp, Imp and
Isc parameters.
6. Output values view area: displays the output voltage value, output current
value and output power value of the current channel.
7. Setting values view area: When CV is prioritized, the voltage setting value,
current upper limit value, current lower limit value, power upper limit value,
and power lower limit value are displayed. When CC is prioritized, the
current setting value, voltage upper limit value, voltage lower limit value,
power upper limit value, and power lower limit value are displayed.
8. PV Curve
9. Displays the relevant parameters of the PV curve file.
