Self-consumption mode:
In this mode, the system prioritizes power supply to the load in the following order: PV (Photovoltaic) > Battery > Grid. It means that the system first uses power generated by the PV panels to supply the load. If the PV power is not sufficient, it will supplement the load with power from both the PV system and the battery. If the combined power is still not enough, the grid will be utilized to meet the remaining power demand. This mode maximizes the use of PV and battery power while reducing reliance on the grid. Any excess power generated by the PV system can be fed back to the grid.
Within this self-consumption mode, users have the flexibility to set up to 6 time periods for battery charging and discharging. This feature allows users to optimize battery usage based on their specific needs and take advantage of time-of-use pricing.
2. Off-grid mode:
When there are issues with the power grid, such as instability or disruption, the inverter will automatically switch to the off-grid mode. This transition occurs within a rapid switching time of fewer than 10 milliseconds, ensuring that critical loads can continue to operate safely without relying on the grid.
The off-grid mode also provides users with the ability to configure parameters related to off-grid backup. It can be seamlessly integrated with the DOD Holding function, enhancing its versatility and suitability for various applications.

The inverter ground and the chassis ground should not be connected at the same point. They need to be separated. The inverter ground serves as a working ground, which maintains a stable voltage relative to the ground during normal operation, ensures accurate measurements of relatively low voltages in the primary system, and discharges lightning current to the ground during lightning strikes. On the other hand, the chassis ground functions as a protective ground, designed to ensure personal safety and reduce the risk of accidents in electrical engineering applications.

A DC arc fault occurs when a loop is formed in the string, resulting in a current output that leads to an arc. This can happen due to various reasons, such as the inverter being operational while directly plugging and unplugging the string, short-circuits between the positive and negative poles of the strings, reversing the polarity of the connections, or having an imbalance in the number of series battery panels.
Solution: To address DC arc faults, follow these steps:
1. Before plugging and unplugging the string, ensure that the inverter has been turned off normally to avoid any arc faults during the process.
2. Check for any instances of positive and negative short-circuits within the string and ensure proper polarity of the connections before connecting to the inverter.
3. When connecting various strings with properly connected positive and negative poles, as well as strings with reversed connections, to the same MPPT input of the inverter, it is important to be aware of the potential for a short-circuit arc to occur. This can happen when positive and negative polarities are mixed, resulting in a short-circuit condition and the formation of an arc.
4. Make sure that you have an equal number of solar panels in each string when connecting them to the inverter. This will help ensure that there is no current flow between the strings that could cause arc faults when plugging or unplugging them. It’s important to balance the strings properly to avoid any potential safety hazards.

To address the issue of string current back-feeding in a photovoltaic system, it is recommended to follow the steps below:
1. Check if there is a difference in the number of solar panels between the affected string and other strings. If there is, wait until the photovoltaic (PV) string current drops below 0.5A, disconnect the DC switch and adjust the solar panel configuration in that string.
2. Inspect if any solar panels in the string are obstructed or shaded.
3. Once the PV string current drops below 0.5A, disconnect the DC switch and check if the open circuit voltage of the string is unusual. If there are any abnormalities, examine the wiring and configuration of the solar panels in that string.
4. Verify if there are any abnormalities in the orientation of the solar panels in the string.

Anti-island protection refers to a safety feature implemented in inverters to prevent the formation of islands during grid disconnection. An island occurs when the inverter and the local load continue to operate independently after the power grid is disconnected, posing safety hazards. To comply with grid-connected standards, the inverter should automatically stop its output within a specified time to prevent the formation of islands and ensure the safety and stability of the overall power system.

No, the inverter can generate both active power and reactive power. The output can be adjusted based on customer requirements, although it is typically set to default to produce full active power.

The following operations need to be carried out on the inverter during the grid connection process:

You should make sure that the AC and DC side wiring of the inverter is correct and that the DC string voltage is normal. Also, set the corresponding grid parameters and check that the AC side voltage of the inverter is normal after completing the AC side grid connection operation. Once you have completed these steps, turn on the inverter’s DC switch and it will automatically detect the AC and DC side environment and complete the grid connection.

If you find that the temperature is too high, here are some steps you can take to address the issue.
1. Make sure that the ventilation in the inverter’s installation location is adequate, and check that the inverter fan is functioning properly.
2. Take a look at the inverter’s temperature-related parameters and analyze the operating data to see if there are any overtemperature alarms or relevant temperature data recorded in the detection system.
3. Inspect the inverter’s installation to see if there is any direct sunlight irradiation, as this could contribute to high temperature readings.

The maximum short-circuit current refers to the maximum allowable current measured by short-circuiting the positive and negative terminals. On the other hand, the maximum input current pertains to the maximum output current value that allows the string to operate normally.

Yes, it can have an impact. The MPPT algorithm aims to find the maximum power point by adjusting the voltage. When one string of components is occluded, it results in a decrease in voltage for the affected string. This situation can lead to the presence of two power peak points, causing the MPPT tracking point to be lower than usual, which ultimately reduces the overall power generation efficiency.

To ensure your safety and the proper functioning of your equipment, it’s important to follow the correct sequence of steps when dealing with power outages and grid connections. During a power outage at the power station, it’s recommended to turn off the DC switch (module side) first, followed by the AC switch (inverter side). On the other hand, when connecting to the grid for power transmission, it’s important to first close the AC switch and then the DC switch. Remember, the order of operations for power outages and transmission is reversed, so it’s essential to follow the correct sequence to avoid any potential hazards.
