Meaning

PV indication

LED1

LED4

-

Steady green

-

At least one PV string is properly connected, and the DC input voltage of the corresponding MPPT circuit is at least 500 V.

Blinking green at long intervals

-

The test on the cable connection of PV strings is complete, cables are correctly connected, and the buzzer does not buzz.

Blinking red at long intervals

-

The test on the cable connection of PV strings is in progress and the buzzer does not buzz.

Steady red

-

The test on the cable connection of PV strings is complete, cables are incorrectly connected, and the buzzer buzzes.

Blinking green at short intervals

Red

An environmental fault occurs at DC side.

Off

-

The inverter disconnects from all PV strings, or the DC input voltage of all MPPT circuits is less than 500 V.

Grid-tied indication

LED2

LED4

NA

Steady green

-

The inverter is in grid-tied mode.

Blinking green at short intervals

Red

An environmental fault occurs at AC side.

Off

-

The inverter is not in grid-tied mode.

Communications indication

LED3

-

Blinking green at short intervals

The inverter receives data over RS485 or MBUS communication.

Off

The inverter has not received data over RS485 or MBUS communication for 10 seconds.

Alarm/O&M indication

LED4

-

Steady red

A major alarm is generated.

Blinking red at short intervals

A minor alarm is generated.

Blinking red at long intervals

A warning alarm is generated.

Steady green

Local maintenance succeeds.

Blinking green at long intervals

In local maintenance or shuts down over a command.

Blinking green at short intervals

Local maintenance fails.

Off

No alarm is generated, and no local maintenance operations are performed.

NOTE:
  • Local maintenance refers to operations performed after a universal serial bus (USB) flash drive, Bluetooth module, WLAN module, or USB data cable is inserted into the USB port of the inverter. For example, local maintenance includes configuration import and export using a USB flash drive, and connecting to the SUN2000 app over a Bluetooth module, WLAN module, or USB data cable.
  • If the alarming and the local maintenance happen concurrently, the alarm/maintenance indicator shows the local maintenance state first. After the USB flash drive, Bluetooth module, WLAN module, or USB data cable is removed, the indicator shows the alarm state.
