Frequently Asked Questions - LSG-3 Deye

How do I install the Deye LSG-3 inverter?

Installation must be performed by a qualified electrician. Mount the inverter on a wall or structure using the provided bracket, ensuring proper ventilation. Connect the DC input from solar panels, the AC output to the grid, and the communication cables as per the manual. Refer to the installation guide for detailed steps.

What is the maximum input voltage for the LSG-3?

The maximum input voltage (DC) is 800 V. Do not exceed this limit to avoid damage to the inverter.

Can the LSG-3 operate during a power outage?

The LSG-3 is a grid-tied inverter and will shut down during a power outage for safety reasons (anti-islanding). To have backup power, you need a hybrid inverter with battery storage, such as Deye's hybrid models.

How do I clean and maintain the inverter?

Keep the inverter free of dust and debris. Use a dry cloth to clean the exterior. Check the cooling vents for blockages. Do not use water or solvents. Regular visual inspection is recommended.

What does the error code 'E01' mean on the display?

Error code E01 indicates a grid overvoltage condition. Check the AC grid voltage and ensure it is within the inverter's acceptable range. If the problem persists, consult a technician.

Is the LSG-3 compatible with Wi-Fi monitoring?

Yes, the LSG-3 supports an optional Wi-Fi module for remote monitoring via the Deye app. The module can be plugged into the communication port.

What is the warranty period for the Deye LSG-3?

The standard warranty is 5 years. Extended warranty options may be available from your installer.

Can I connect batteries to the LSG-3?

No, the LSG-3 is a standard grid-tied inverter without battery support. For battery storage, consider Deye's hybrid series.

How do I update the firmware on the LSG-3?

Firmware updates can be performed via the RS485 connection using the Deye Update Tool. Contact technical support for the latest firmware file and instructions.

What should I do if the inverter is not producing power?

Check if the DC input voltage is within range (above 200 V), ensure the AC breaker is on, and verify no error codes on the display. If all else fails, contact support.

The maximum number of microinverters allowed for each branch depends on the model of the microinverter. And the total number of microinverses of the system is not allowed to exceed the maximum number of microinverter allowed of MECD.

Interface Explanation

Interface position

All of the MECD interface as below, from left to right, are Network port, DI and Power Connection Port.

RS485: This port function is reserved.

DI: Digital input. When the DI status changed from 1 to 0, the MECD will send command to control the microinverter shutdown immediately via Zigbee or PLC.

Power connection port: L1, L2, L3, N, PE, connects power through the power line. Power cable included in the MECD package.

Preparation

Make sure you have the following things taken care of before attempting to install the ECD:

● A dedicated standard AC electrical outlet (located electrically as close to the array as is possible).
● A broadband Internet connection is available for your use.
● Wireless router is available for you use a laptop.
With a web browser (to view the EMA online monitoring application).
● A pre-programmed MECD.

Selecting an Installation Location for the MECD

● A location that is electrically as close to the array asis possible-preferably a dedicated outlet installed directly to the solar system sub-panel.
The ECD is not rated for outdoor use, so if installing outdoors near a junction box or breaker panel, making sure that you enclose it in an appropriate weather proof NEMA electrical box.
● Using wall-mounted
When mounting the MECD on the wall, make sure to select a cool, dry, indoor location.
- Depending on the wall surface you are mounting the MECD, use either two #4 drywall screws or wall anchors, installed 122.5 mm apart. The drywall screws and wall anchors are NOT included in the MECD kit.
- Align and slide the MECD onto the mounting screws.

Connections

1. Connect the power cable to the power connection port on the bottom of the ECD;
2. Config the wifi device with your home router.
