As the accumulated total power is stored, total generation power can be checked.
5.1.3 Initialization and action for abnormality
In case the inverter stops due to any errors, error indication is shown on the screen. At this time, examine the
reason why any error occurs, remove the fault cause and then re-run the inverter. When the same problem
happens or the inverter does not re-run, you should contact Dass tech or Installer.
Fault scan is stored 100 in the order in which they were generated in the past from 0 to 99 and the most recent
one is No. 0. By using the Up/Down key on the keypad inside the inverter, it is able to find out the situations of
the fault occurrences from the past or variables.
When the inverter is stopped, it is able to change the parametric value by using the inner keypad.
There are two initializations, which is Parameter initialization and Fault initialization. Parameter initialization
sets every parameter or selection function to the Factory Default, and Fault initialization deletes the fault records
occurred in the past and sets to ‘ready’ mode.
Controlling the inner keypad randomly shall cause malfunction of the inverter. You should contact DASS tech..
5.1.4 Fault
1) Fault
Input Overvoltage (DC OV)
In case the voltage of solar cells is higher than the specified value, stop the system to protect the inverter.
Output Over-current (Over current)
In case the output current of the inverter is over-current due to abnormal load status, stop the system to protect
the inverter.
Inverter Overheat (Over heat)
In case the temperature inside the inverter is higher than 95
℃
, stop the system to prevent overheat. If the
temperature inside the inverter returns to normal, operate the inverter normally after reset.
Earth fault
In case the current leaks due to abnormal earth, stop the system.
Line failure (Over/Under frequency, Over/Under voltage)
When abnormality occurs in the grid power, stop the system. (Anti-islanding, protection of system over/under-
voltage, protection of system low voltage, protection of system over/under-frequency, protection of system low-
frequency)
Abnormal PWM control (Over current 2)
If there is abnormal status found in PWM control inside the inverter, stop the system
