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 7.3, 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 7.4.

4. Operate the bu�on [up down], move se�ng cursor to energy meter and press the bu�on
[enter]. At this �me you can turn on or turn off the energy meter by choosing [up down]
bu�on, please press [enter] bu�on to confirm when se�ng done.
5. Move the cursor to [OK], 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 displays [meter power XXW], the zero-export
func�on se�ng is completed. Shown as picture 7.15.

7.2 Sensor Clamp(op�onal)
The inverter has integrated export limita�on func�on.The func�on is to adjust the output of
inverter quickly according to the power of the user and solar panels, prevent the output of the
inverter from being fed to the power grid. This limiter func�on is op�onal. If you buy the
inverter with limiter, a current sensor will be included in the package which is necessary for
limiter func�on.
7. Meter power XXW shows posi�ve means grid is supplying the load, and no power fed into
grid. if meter power shows nega�ve, it means PV energy is being sold to grid or energy meter
wiring connce�on has problem.
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 keep a certain output to counteract
the power of the grid without backflow .
