7.3 Use of limiter func�on
When the connec�on is completed, the following steps should be refered to use this func�on:
1. Turn on the AC switch.
2. Turn on the DC switch, wai�ng for the inverter's LCD is turned on.
3. Press Enter bu�on on the LCD panel in the main interface into the menu op�ons, select
[parameter se�ng] to enter setup submenu, and then select [running parameters] as shown
in picture 7.8, at this �me please input the default password 1234 through pressing the
bu�on [up down, enter], enter the opera�on parameter se�ng interface, shown as
picture 7.9.

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

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 .
