The connection of the ground line
Good grounding is good for resisting surge voltage shock and improving EMI performance.Therefore, before connecting AC, DC and communication cables, you need to ground the cable firstly. For a single system, just ground the PE cable. For multiple machine systems, all PE cables of the inverter need to be connected to the same grounding copper platoon to ensure the equipotential connection. The installation of the shell ground wire is shown as picture .. The external protective earthing conductor is made of the same metal as the phase conductor.

7. Zero-export funcon via energy meter
There’re two kinds of energy meters for this series inverter. First type is Eastron SDM-Modbus V which is able to measure the Max. A current directly. More details please refer to Pic . & .. For the Eastron SDM MCT mA, it needs external CT to measure the current. The CT power range is from A-A. More details about the Eastron SDM MCT, please refer to Pic . & .. Also, the CHNT meter DTSU is supported, it can measure the Max. A current directly. More details about the DTSU, please refer to Pic . & .. When you are reading this, we believe that you have completed the connection according to the requirements of chapter , if you have been running your inverter at this time, and you want to use the zero-export function, please turn off AC and DC switch of the inverter, and wait for minutes until the inverter completely discharged.Please follow below Picture . to connect the energy meter. For system wiring diagram, the red line refers to L line (L, L, L), the black line refers to the neutral line (N). Connecting energy meter RS cable to inverter’s RS port. It’s recommended to install an AC switch between the inverter and the utility grid, the specs of the AC switch are determined by the power of load. If there is no integrated DC switch inside the inverter you purchased, we commend you to connect the DC switch. The voltage and current of the switch depend on the PV array you access.

. Multiple strings and parallel connection meters
This application is that when the string inverters work in parallel, there is only one power grid and one load, and only one meter can be connected to prevent reverse current, so only this many-to-one anti-reverse current connection can be connected. If there’s several inverters in a plant, also it can use pcs meter to realize zero export function. For example,if there’s pcs inverter in the system with pcs meter.We need to setup pcs inverter as the master and others setup as slaves. And, all of them need to connect to the meter via RS. Below is the system diagram and configuration of the system.

Use of zero-export function

When the connection is completed, the following steps should be refered to use this function: . Turn on the AC switch. . Turn on the DC switch, waiting for the inverter’s LCD is turned on. . Press Enter button on the LCD panel in the main interface into the menu options, select
[parameter setting] to enter setup submenu, and then select [running parameters] as shown in picture ., at this time please input the default password through pressing the button [up down, enter], enter the operation parameter setting interface, shown as picture ..

Pic . Meter switch

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

Meter Power: 20W
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 or energy meter wiring conncetion has problem. . 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 .

– –

. 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.

. 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 above diagram. 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”.

9. 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.
10.Error informaon 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.
