4. Operate the button [up down], move setting the cursor to limiter function, and press the button
[enter]. At this time, you can turn on or turn off the limiter function by choosing [up down] button.
Please press [enter] button to confirm when the setting is done.
5. Move the cursor to [confirm], press ENTER to save the settings, and exit the running parameters
page. Otherwise, the settings are invalid.
6. If set up successfully, you can return to the menu interface and display the LCD to [output data]
by press the [up down] button. If it is displayed as [grid power], the limiter function settings will be
completed. See Figure 26.
Figure 26 - Limiter function turned on.
7. [grid power] showing positive means grid power is consuming energy, and there is no backflow.
If [grid power] shows negative, it means there is no backflow. If [grid power] shows negative, it
means backflow to the grid or current transformer direction error has occurred. Please read more
on Chapter 7.3.
8. After connecting correctly, wait for the inverter starting. If the power of the PV array meets the
current power consumption, the inverter will maintain a certain output to counteract the grid's
power without backflow.
7.3. Notes while using limiter function
Warning:
Under limiter function, we strongly recommend that the two PV arrays are formed by the
same number of PV panels of the same size, which will make the inverter more responsive
to limit the power.
Shock Hazard:
When using the limiter function, you need to ensure that the PV input's opening voltage is
no more than 450V. Otherwise, it may cause inverter malfunction. Do not have this
limitation if the inverter is not working under the limiter function.
