2. Fault recovery (Temporary Fault)
The KP100G’s Data Logger continuously monitors the system status. When unexpected conditions such as grid problems or system fault which defined
in “error message table” occur and the inverter recovers itself within 48 hours, the LCD turns yellow color.
3. Fault (Permanent Fault)
The status of disconnection due to system fault and inverter failure defined in “error message table”. The inverter is disconnected from grid at that
moment and the error message is shown and the LCD turns red color. When inverter has problem, there will be “warning” or “fault” followed by
“Status”. And an additional message of warning or fault situation is showed and blinking below “Status” line.
4. Shutdown
If DC voltage decreases than 200VDC at the moment of reduced sunlight, the KP100G automatically shuts down. The display is not shown and the
operation keys are inactive.
Daily graph
By pressing “ ” key in text display, the display is switched to daily display as above. The principles of design are:
Time-axis (x-axis): 12 hours maximum can be displayed. The first data of a day is plotted on the left most point. Until the first set point, the
time axis then shows the number. Every hour is divided into 10 points, each point is the average power during 6 minutes.
Power-axis (y-axis): Fixed value from 0 to 12kW. Every segmentation indicates 1kW.
Date information: On the upper right corner, the date of present display is shown.
Date change: By pressing “ “ and “ ”, user can switch the date he interested. The corresponding date has to be changed in the same manner
More view: If the data recorded in more than 12 hours, user can press
“
OK” to set. After doing that, he can use “ “ and “ ” to shift the time he
interested. But the maximum display on the screen is still 12 hours.
