5.3 Connection of the ground line
Good grounded is important for resist the surge voltage shock and improve EMI’s performance.
So before the connection of AC, DC, communication connections, inverter needs to ground first.
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 equipotent connection. The installation of the shell ground wire is shown as Pic 5.12 The external protective earthing conductor is made of the same metal as the phase conductor.

Table 5.3  Recommened cable specifications
Warning:
Inverter has built-in leakage current detection circuit, If an external leakage current protection device is connected, its operating current must be greater than 300mA or higher, otherwise inverter may not work properly.

The inverter has Wifi function and Wifi Plug in the accessories is used to realize the connection between the inverter and the network. The operation, installation, networking, APP download are detailed in the WIFI PLUG instructions. Figure 5.13  is the Internet monitoring solution.

5.4.1 Installation of datalogger

When installing the WiFi stick, tear off the sealing strip on the inverter. Insert the datalogger into the interface and fix it with a screw. The configuration of the datalogger needs to be performed after various electrical connections have been completed and the inverter DC power on. When the inverter is on the DC power, it is determined whether the datalogger is normally electrified (The LED light shines out of the shell).

5.4.2 Configuration of datalogger
For the configuration of datalogger, please refer to illustrations of the datalogger.

Start up and Shut off

Ensure that the inverter meets the following conditions before starting the inverter, otherwise it may cause fire or damage to the inverter without quality assurance, at the same time the situation on our company does not undertake any responsibility. At the same time, to optimize the system configuration, it is recommended that the two inputs be connected to the same number of PV modules.
a). The maximum open circuit voltage of each set of PV modules shall not exceed 800 Vdc under any conditions.
b). Each input of the inverter better use the same type of PV module in series.
c). Total output power of PV shall not exceed the maximum input power of inverter, each PV modules shall not exceed the rated power of each channel.

6.1 Start up the inverter
When starting up the inverter, should fellow steps below：

1. Starting switch on the AC breaker.
2. Turn on the DC switch of the PV module, and if the panel provides sufficient starting voltage and power, the inverter will start.
3. The inverter will first check the internal parameters and the grid parameters, while the liquid crystal will show that the inverter is self-checking.
4. If the parameter is within acceptable range, the inverter will generate energy. NORMAL indicator light is on.

6.2  Shut off the inverter
Must follow below steps while Shutting down the inverter:

1. Switch off the AC breaker.
2. Wait for 30 seconds, turn off the dc switch (if any), or simply disconnect the dc input connector. The inverter will close the LCD and all led within two minutes.

Zero-export function via energy meter

There’re four kinds of energy meters for this series inverter. First type is Eastron SDM630-Modbus V2 which is able to measure the Max. 100A current directly. More details please refer to Pic 7.1& 7.4. For the Eastron SDM630 MCT 40mA, it needs external CT to measure the current. The CT power range is from 5A-2000A. More details about the Eastron SDM630 MCT, please refer to Pic 7.5 & 7.8. Also, the CHNT meter DTSU666 is supported, it can measure the Max. 80A current directly. More details about the DTSU666, please refer to Pic 7.9 – 7.16.
When you are reading this, we believe that you have completed the connection according to the requirements of chapter 5, 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 5 minutes until the inverter completely discharged.
For system wiring diagram, the red line refers to L line (L1, L2, L3), the black line refers to the neutral line (N). Connecting energy meter RS485 cable to inverter’s RS485 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.

Warning:
In final installation, breaker certified according to IEC 60947-1 and IEC 60947-2 shall be installed with the equipment.

Safety Hint:
Ensuring grid input cables connect 1/4/7/10 port of energy meter, and inverter AC output cables connect 3/6/9/10 port of energy meter when connecting.

1. 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 [run param], at this time please input the default password 1234 through pressing the button (up down, enter], enter the operation parameter setting interface, shown as picture 7.17.
2. Operate the button [up down], move setting cursor to energy meter and press the button [enter]. At this time you can turn on the energy meter by choosing [up down] button, please press [enter] button to confirm when setting done.
3. Move the cursor to [OK], press [enter] to save the settings and exit the running parameters page, otherwise the settings are invalid.
4. lf 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 7.18.
5. Meter power 428 W 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.
6. 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 .

7.1 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’re several inverters parallelling operation in a plant, also it can use 1 pcs meter to realize zero export function.For example, if there’re 3 pcs inverters parallelling operation in the system with 1 pcs meter.We need to setup 1 pcs inverteras the master and others setup as slaves. And, all of them need to connect to the meter via RS485 .Below is the system diagram and configuration of the system.![Deye SUN-K-GP-EU-AM-LV Grid Connected PV Inverter

When the frequency exceeds StopPoint: 51.5Hz, the inverter output should stop (ie 0 W).
When the frequency is lower than StopPoint: 51.5 Hz, the inverter will linearly increase the power output with a gradient of 100% Pmax/Hz until it reaches StopPoint: 50.5 Hz.
In the hysteresis mode, when the frequency is lower than StopPoint: 51.5 Hz, the inverter will not increase the power output until it is lower than RecoverPoint: 50.1 Hz.The inverter provides a reactive power regulation function.
Tap Reactive Power Regulation Mode to select proper regulation mode and set the corresponding parameters.

• “OFF” Mode
  The reactive power regulation function is disabled. The PF is fixed at +1.000

• ReactiveP
  Adjust reactive power output in %.

• “PF” Mode

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.
