Pic . Zero-export function via energy meter turn on . 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. . 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 .
. 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.

.. Zero-export function via CT
When you are reading this, we believe that you have completed the connection according to the requirements of chapter , 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 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 ., 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 .. 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.

. 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)

. 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 .. 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”

. Repair and Maintenance
String type inverter doesn’t need regular maintenance. However,debris or dust will affect heat sink’s thermal performance. It is better to clean it with a soft brush. If the surface is too dirty and affect the reading of LCD and LED lamp, you can use wet cloth to clean it up.

High Temperature Hazard: When the device is running, the local temperature is too high and the touch can cause burns. Turn off the inverter and wait for it cooling, then you can clean and maintain.
Safety Hint: No solvent, abrasive materials or corrosive materials can be used for cleaning any parts of the inverter.

.Error information and processing
Inverter has been designed in accordance with international grid tied standards for safety, and electromagnetic compatibility requirements. Before delivering to the customer the inverter has been subjected to several tests to ensure its optimal operation and reliability.
. Error code
If there is any failure,the LCD screen will display an alarm message. In this case,the inverter may stop feeding energy into the grid. The alarm description and their corresponding alarm messages are listed Table ..
