Huawei inverters | The main technical indicators of pv inverters

In a photovoltaic system, the energy emitted by the solar cell is first stored by the battery and then inverted by the pv inverter into 220V or 380V AC. However, the battery is affected by its own

Appearance

Local maintenance refers to operations performed after a USB flash drive or USB data cable is inserted into the USB port of the inverter. For example, import and export configurations using

System Power-On

Turn on the DC switch between the PV string and the inverter if there is any. Turn on the DC switch at the bottom of the inverter. Observe the LEDs to check the inverter operating status.

Powering On the Inverter

Off The inverter is not in grid-tied mode. Steady red If the alarm/maintenance indicator is red, an internal fault on the AC side of the inverter was generated. Communication indicator Blinking

Indicator Status

The PV connection indicator and the grid connection indicator preferentially indicate environmental faults. Local maintenance refers to operations performed after a USB flash

Huawei PV inverter steady-state mode

If the PV modules receive no sunlight, the battery works in discharge mode, and the battery reaches the end-of-discharge capacity, the inverter enters Shutdown mode.

Powering On the System

Before the equipment is put into operation for the first time, ensure that the parameters are set correctly by professional personnel. Incorrect parameter settings may result in noncompliance

System Power-On

Category Status Description Running indicator LED1 LED2 – Steady green Steady green The inverter is running in on-grid state. Blinking green slowly (on for 1s and off for 1s) Off The DC is

Setting Active Power Control

To enable this function, you need to set power meter, inverter, and grid connection with limited power parameters. This section describes how to set grid connection with limited power

SUN2000 power-on

If the off-grid load is overloaded, indicators LED1 and LED2 on the inverter blink orange slowly. Reduce the off-grid load power and manually clear the alarm or until the inverter is recovered.

Powering On the Inverter

If the DC power supply is connected but the AC power supply is disconnected, the inverter will report a Grid Failure alarm. The inverter can start properly only after the power grid recovers.

(Optional) Power-On in On-Grid Mode or by Starting the

If the PV strings are equipped with optimizers or receive no solar irradiance, power on the system in on-grid mode or by starting the generator. During power-on and commissioning, ignore the

6 FAQs about [Huawei PV Inverter Steady-State Mode]

What are the characteristics of Huawei inverters?

Huawei inverters, specifically the Huawei SUN2000L series, have the following characteristics: They incorporate the latest technology for residential use and have a power range from 2000w to 5000W. An intelligent solar panel optimization system, optimizers, is also a feature of these inverters.

How does a PV inverter work in standby mode?

The inverter enters Standby mode after detecting that the PV string output power is not suitable for connecting to the power grid for generating power. If the PV modules receive no sunlight, the battery works in discharge mode, and the battery reaches the end-of-discharge capacity, the inverter enters Shutdown mode.

What does standby mode mean on an inverter?

In Standby or Operating mode, the inverter enters Shutdown mode after detecting a fault or shutdown command. In Shutdown mode, the inverter enters Standby mode after detecting a startup command or that the fault is rectified. In Shutdown mode, if the black start button of the battery is pressed, the inverter enters Operating mode.

How does a PV inverter work?

The inverter tracks the maximum power point to maximize the PV string output. If the inverter detects a fault or a shutdown command, it enters the Shutdown mode. The inverter enters Standby mode after detecting that the PV string output power is not suitable for connecting to the power grid for generating power.

What is a Huawei power optimizer?

The Huawei Power optimizers are module-level buck-only optimizers. These are only compatible with some Residential and Commercial Inverters of the SUN2000 and SUN5000 series from Huawei. The optimizer has to permanently communicate with its inverter, through the DC connections.

What mode does an inverter work in?

The inverter can work in Standby, Operating, or Shutdown mode. The inverter enters Standby mode when the external environment does not meet the operating requirements. In Standby mode:
