Frequently Asked Questions - VSG-3 Deye

What is the recommended cable size for DC input?

For the Deye VSG-3, use 4 mm² to 6 mm² PV cables with MC4 connectors. Ensure proper polarity and secure connections.

How do I reset the inverter?

Press and hold the reset button on the side panel for 5 seconds. Alternatively, power cycle the unit by disconnecting AC and DC for 1 minute.

Can I monitor the inverter remotely?

Yes, the VSG-3 supports optional Wi-Fi dongle for monitoring via the Deye app. Connect to RS485 port for local monitoring.

What is the maximum number of solar panels I can connect?

With two MPPT trackers, each handling up to 3000W, you can connect up to 10 panels (300W each) per tracker, depending on voltage limits.

Does it work during a power outage?

No, the VSG-3 is a grid-tied inverter and will shut down during grid outage for safety (anti-islanding). For backup, consider a hybrid or battery inverter.

How often should I clean the inverter?

Clean the exterior with a soft dry cloth every 6 months. Avoid water on electrical parts. Ensure vents are dust-free for proper cooling.

What error codes are common?

Common codes: E01 (Grid overvoltage), E04 (Isolation fault), E08 (Over temperature). Refer to manual for full list and troubleshooting.

Can I install the inverter outdoors?

Yes, the IP65 rating allows outdoor installation. Avoid direct sunlight and ensure adequate airflow. Mount on a wall with at least 20 cm clearance.

How do I update the firmware?

Firmware updates are done via the Deye Service Tool connected to the RS485 port. Download the latest firmware from Deye's website and follow instructions.

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.
