DEYE SUN-30K-G02-LV (01) PDF Document

The following safety symbols highlight potential risks during the operation of the DEYE SUN-30K-G02-LV:

Warning: Indicates important safety instructions which, if not correctly followed, could result in serious injury or death.

Shock Hazard: Indicates important safety instructions regarding electric shock risks that could result in electric shock if ignored.

Safety Hint: Indicates instructions that, if not followed, could result in damage to or the destruction of the inverter.

High Temperature Hazard: Indicates a hot surface; failure to follow instructions could result in burns.

When operating the DEYE SUN-30K-G02-LV, follow these requirements:

1. The inverter should be installed and maintained only by qualified persons under local standard regulations.

2. Always disconnect the AC side first, then the DC side, during installation and maintenance. After disconnection, wait at least 5 minutes before touching any components to avoid electric shock from remnant electricity.

3. The local temperature of the inverter may exceed 80 degrees Celsius during operation. Do not touch the case to avoid injury.

4. All electrical installation must comply with local electrical standards and be approved by the local power company.

5. Take appropriate anti-static measures.

6. Install the unit in a location where children cannot touch it.

7. Prohibit grounding the positive and negative poles of the PV string, as this will damage the inverter.

To ensure safe operation and prevent fire risks, consider these criteria for the DEYE SUN-30K-G02-LV installation:

Do not install the inverter in areas containing highly flammable materials, gases, or potentially explosive atmospheres.

Do not install in small, closed spaces where air cannot circulate freely. Blocked airflow can lead to overheating.

Avoid exposure to direct sunlight and rain, as sunlight increases operational temperature and may cause output power limiting. A sun shade is recommended if ambient temperatures exceed 40 degrees Celsius (100 degrees Fahrenheit).

The wall or structure must be strong enough to bear the weight of the unit.

Install the unit vertically with a maximum incline of +/-15 degrees. Tilting beyond this limit can inhibit heat dissipation.

To ensure proper ventilation for the DEYE SUN-30K-G02-LV, maintain the following minimum clearances:

Above: 500mm

Below: 500mm

Sides (to other inverters or walls): 500mm

Front: 1000mm

The front panel of the DEYE SUN-30K-G02-LV features four indicators:

The DEYE SUN-30K-G02-LV panel includes four buttons for the following functions:

UP Button: Used for page turning (moving up) and increasing parameter values.

DOWN Button: Used for page turning (moving down) and decreasing parameter values.

ESC Button: Used to exit or move left when modifying adjustable parameters.

ENTER Button: Used to confirm selection or move right when modifying adjustable parameters.

For the DC input connection of the DEYE SUN-30K-G02-LV, use the following cable specifications:

Cable Type: Industry generic PV cable (model: PV1-F)

Cross Section Range: 4.0 to 6.0 mm² (12 to 10 AWG)

Recommended Value: 4.0 mm² (12 AWG)

Maximum PV Array Open Circuit Voltage: Must be within 1000V.

The DEYE SUN-30K-G02-LV requires a copper core cable for the AC terminal. The recommended range for the conductor cross-sectional area is 25 to 50 mm².

The AC wiring sequence is as follows:

L1: Connected to socket 1

L2: Connected to socket 2

L3: Connected to socket 3

PE Line: Connected to the earth

N Wire: Connected to the N socket

According to the technical specifications for the DEYE SUN-30K-G02-LV:

Rated Output Power: 30 KW

Rated Voltage: 400V

Recommended Current Protection Device: 60A

Follow these steps to start the DEYE SUN-30K-G02-LV:

1. Ensure all PV modules are within the 1000Vdc maximum open voltage limit.

2. First, switch on the AC breaker.

3. Turn on the DC switch of the PV module. If the panels provide sufficient starting voltage and power, the inverter will start.

4. The inverter will check internal parameters and grid parameters; the LCD will display “self-checking”.

5. If parameters are within the acceptable range, the inverter will generate energy and the “NORMAL” indicator light will turn on.

To safely power down the DEYE SUN-30K-G02-LV:

1. Switch off the AC breaker.

2. Wait for 30 seconds.

3. Turn off the DC switch (if equipped) or disconnect the DC input connector. The inverter will close the LCD and all LEDs within two minutes.

To set up the zero-export function via the SUN limiter for the DEYE SUN-30K-G02-LV:

1. Turn on the AC switch and the DC switch. Wait for the LCD to light up.

2. Press “Enter” on the LCD panel to access menu options. Select [Setup], then [Run Param].

3. Input the default password “1234” using the UP/DOWN and ENTER buttons.

4. Move the cursor to “Limiter” and press ENTER. Use the UP/DOWN buttons to toggle the function to “ON”. Press ENTER to confirm.

5. Move the cursor to [OK] and press ENTER to save the settings and exit. If successful, the home page will display “utility power” or “meter power”.

The DEYE SUN-30K-G02-LV does not require regular maintenance. However, dust or debris on the heat sink can affect thermal performance. Follow these cleaning guidelines:

Clean the heat sink with a soft brush.

If the surface or LCD is very dirty, use a wet cloth to clean it.

Warning: Never use solvents, abrasive materials, or corrosive materials for cleaning any parts of the inverter.

Warning: When the device is running, the local temperature is too high. Turn off the inverter and wait for it to cool down before cleaning.

The DEYE SUN-30K-G02-LV displays error codes on its LCD if a failure occurs. Common codes include:
