- Country:
allowed to choose a different country setting. - Reclosure time:
allowed to change the reclosure time.
- Country:
- Insulation: Allowed to enable/disable Insulation detection.
- DC Injection: Allowed to enable/disable DC injection detection.
- Uac/Freq. Protection: Allowed to change UAC/Freq. protection setting. The key value in the blank, if the value is out of the range, it will not be modified in the inverter side.

- Active Power:
- Enable/Disable this function
- PM(%):
control the max output power percentage (0~100%) - Ramp up power (%):
ramp up rate per minute (max 6000)
- Reactive Power:
- Mode:
Select reactive power mode - Fixed cosΦ:
when in “Constant cosΦ “mode, the value can be controlled here Fixed Q:
when in “Constant Q “mode, the value can be controlled here
- Response time:
decide the response time for all reactive power function
- Mode:
- Q(U) Ctrl:
- Q(U) function will be controlled in the “Reactive Power ”page
- Lock-in Power: when active power is higher than this value, this function starts working
- Lock-out Power: when active power is lower than this value, this function stopped working
- P(U) Function:
- Q by Night:
- Mode:
- Select reactive mode to “Fixed kvar 24/7”
- Set specific percentage for reactive power.
- Q setting 24/7 allows inverter to generate fixed reactive power at night.
- Range of ConstQ_Percent: -100%~+100%
- Mode:
- Q(P) Function Setting:
This function is only applied for VDE4110, customer can set different (P,Q) points to determine the behavior of inverter.
- P-F Control:
- Cos(Φ) of P Ctrl: It will be controlled in “Reactive Power ”page.
- FRT: Some grid code required FRT function, different behavior can be made by this part.(Only a person with permission from Delta can modify the value).
- Fan Test: You can use fan test function to test the fan.
- Fan Fail: Showing the defective fan during the fan test.
- Fan Fail: Showing the defective fan during the fan test.
- Anti-PID:
When Trip time is ‘0’ means this function is disabled, if the value has been set, the anti-PID function will start after 30 mins when the inverter status shows “No DC”.
Set specific value for anti-PID function active time. Range of Trip Time value: 0~11 (hour) - ARC: When Arc is detected, the inverter will be locked, the user can use “un-lock” to unlock the inverter.
- Dry Contact: The user can set different trigger conditions for the dry contact relay to make the external alarm device work.
- Multi-function Relay: Same as dry contact function, but includes more application combinations.
Other Functions
- Sync Clock: synchronize the inverter’s time with your laptop’s
- Firmware: for FW upgrade
After first connection, press”
”to load FW file.
After the file is loaded, the current FW version will shown in yellow, you can know whether the FW needs to be upgraded or not.
If yes, press “
”.
When the upgrade is finished, “FIRMWARE UPGRADE COMPLETED” will be shown.
- Language: Three languages available(English /German/French)by clicking the national flag.
- Protocol: Switch between Sunspec & Delta protocol.
Notice:
If switched to Sunspec, there will be no readings in DSS because DSS is for Delta protocol - Grid Load:
Enter the password you got.
“Config_ID1” can be found in the “ConfigLog” folder, and settings can be implemented to other inverters. - Grid save: save the Grid setting as “Config_ID1” in the “ConfigLog” folder
- Datalog: log data on Main page
- Time intervals can be chosen.
- Data will be in the “Datalog” folder.
