Pic 7.10 Limiter func�on turn on
Utility Power:
20W

Limiter
4. Operate the bu�on [up down], move se�ng cursor to limit func�on and press the bu�on [enter].
At this �me you can turn on or turn off the limit func�on by choosing [up down] bu�on, please
press [enter] bu�on to confirm when se�ng done.
5. Move the cursor to [confirm] , press ENTER to save the se�ngs and exit the running parameters
page, otherwise the se�ngs are invalid.
6.If set up successfully, you can return to the menu interface, and display the LCD to [home page]
by press the [up down] bu�on. If it displayed as [u�lity power], the limiter func�on se�ngs will
be completed. Shown as picture 7.10.
7. [u�lity power] showing posi�ve means grid power is consuming energy, and there is no
backflow. If [u�lity power] shows nega�ve, which means there’s excess PV energy flows to
grid or current transformer arrow direc�on is in wrong direc�on. Please read more on
chapter 7.9.
8. A�er properly connec�on is done, wait for inverter star�ng. If the power of the PV array
meets the current power consump�on, the inverter will maintain a certain output to
counteract the power of the grid without backflow .
Safety Hint:
While the u�lity power is nega�ve and inverter has no output power, that means
the orienta�on of the current sensor is wrong, please turn off the inverter and
change orienta�on of the current sensor.
(when using limiter, the arrow of current sensor points to the grid)
7.4 Notes while using zero export func�on
For your safety and the opera�on of limiter func�on of the inverter, we put forward the
following sugges�ons and precau�ons:
Warning:
Under zero export mode 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.
