1. Operate the button [up down], move setting cursor to energy meter and press the button [enter]. At this time you can turn on or turn off the energy meter by choosing [up down] button, please press [enter] button to confirm when setting done.

2. Move the cursor to [OK], press [enter] to save the settings and exit the running parameters page, otherwise the settings are invalid.

3. If set up successfully, you can return to the menu interface, and display the LCD to [home page] by press the [up down] button. If it displays [meter power XXW], the zero-export function setting is completed. Shown as picture 7.21.

Pic 7.21 Zero-export function via energy meter turn on

1. Meter power XXW shows positive means grid is supplying the load, and no power fed into grid. if meter power shows negative, it means PV energy is being sold to grid.

2. After properly connection is done, wait for inverter starting. If the power of the PV array meets the current power consumption, the inverter will keep a certain output to counteract the power of the grid without backflow.

7.2 Sensor Clamp(optional)

The inverter has integrated export limitation function. The function 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 function is optional. If you buy the inverter with limiter, a current sensor will be included in the package which is necessary for limiter function.

7.2.1 Zero-export function via CT

When you are reading this, we believe that you have completed the connection according to the requirements of chapter 5, if you has been running your inverter at this time, and you want to use the limiter function, please turn off AC and DC switch of the inverter, and wait for 5 minutes until the inverter completely discharged. Then connect the current sensor to the inverter limiter interface. Make sure they are reliably connected, and the current sensor should clamp to the live wire of the incoming line. In order to make it easier for you to use the built-in limiter function of the inverter, we have specifically given the wiring diagram, as shown in Picture 7.23, the red lines connected to the utility grid said wire (L), blue line shows the zero line (N), yellow green line shows the ground wire (PE). We recommend installing a AC switch between the inverter outlet and the utility grid, the specs of the AC switch is determined according to the load capacity. The AC switch we recommend to connect to the inverter output can refer to Table 5.1. If there is no integrated DC switch inside the inverter you purchased, were commend you to connect the DC switch. The voltage and current of the switch depends on the PV array you access.

2. Move the cursor to [confirm], press ENTER to save the settings and exit the running parameters page, otherwise the settings are invalid.
3. If set up successfully, you can return to the menu interface, and display the LCD to [home page] by press the [up down] button. If it displayed as [utility power], the limiter function settings will be completed. Shown as picture 7.26.

\* This item is not available for some FW verison

Pic 7.26 Limiter function turn on

1. [utility power] showing positive means grid power is consuming energy, and there is no backflow. If [utility power] shows negative, which means there’s excess PV energy flows to grid or current transformer arrow direction is in wrong direction. Please read more on chapter 7.
2. After properly connection is done, wait for inverter starting. If the power of the PV array meets the current power consumption, the inverter will maintain a certain output to counteract the power of the grid without backflow.

7.4 Notes while using zero export function

For your safety and the operation of limiter function of the inverter, we put forward the following suggestions and precautions:

Safety Hint:

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.

Safety Hint:

While the utility power is negative and inverter has no output power, that means the orientation of the current sensor is wrong, please turn off the inverter and change orientation of the current sensor.

(when using limiter, the arrow of current sensor points to the grid)

7.5 How to browse the load power of your PV grid-tie plant on monitoring platform?

If you want to browse load power of the system and how much energy (KWH) does it export to grid(inverter output power is used to power the load firstly and then the surplus energy will feed into grid). You also need to connect the meter according to Pic 7.12. After the connection completed successfully, the inverter will show the load power on the LCD. But please don't setup "Meter ON". Also, you will be able to browse the load power on the monitoring platform. The plant setting method as below description.

Firstly, go to the solarman platform(https://pro.solarmanpv.com, this link is for solarman distributor account; or https://home.solarmanpv.com, this link is for solarman end user account;) plant home page and click “edit”

And then choose your system type as "Self-consumption"

Secondly, go to plant page, if it shows the PV power, load power and grid power, which means the configuration is correct.
