FAQ

1. Have any design tool and how to use it?

Shine Design is the system design software just for inverters, It can conduct installers to figure out panel numbers for a system, panel numbers for each string, and which inverter model is suitable for the system. Moreover, it can print a design report after input all necessary parameters, can calculate DC/AC wire wastage, annual generation, etc.

2. Does the inverter have monitoring solutions for residential system?

For small rating system, we have wired two monitoring solution (ShineNet via RS232 or RS485). (a) Local wireless monitoring solution (ShineVision via RF module communication) (b) Global wireless monitoring solution (WIFI module via WIFI network)

3. Do you have free solution for monitoring?

ShineNet is an inverter monitoring software run in Windows XP, Windows Vista, Windows 7 operating system. It can monitor inverter via RS232 (or RS232 convert to USB cable) and RS485 wire connection. Customers can purchase the cable locally to get the inverter monitored, it is simple.

Q: What is the role of a surge protector in a solar inverter?: The role of a surge protector in a solar inverter is to safeguard the inverter and connected electrical equipment from voltage spikes and power surges that can occur due to lightning strikes, grid fluctuations, or other electrical disturbances. It helps to prevent damage to the inverter and ensures the stability and longevity of the solar power system.

Q: What is the role of an anti-islanding feature in a solar inverter?: The role of an anti-islanding feature in a solar inverter is to ensure the safety of utility workers during power outages. It detects when the grid goes down and immediately disconnects the solar system from the grid to prevent the flow of electricity back into the grid. This prevents the potential danger of utility workers being exposed to live electricity while working on the grid.

Q: Can a solar inverter be used in areas with unstable grid connections?: Yes, a solar inverter can be used in areas with unstable grid connections. Solar inverters are designed to convert the DC power generated by solar panels into usable AC power for consumption or to be fed back into the grid. In areas with unstable grid connections, solar inverters can still function and provide power by utilizing battery storage systems or operating in off-grid mode. This allows for uninterrupted power supply and provides stability in areas with unreliable grid connections.

Q: How is a solar inverter connected to the solar panels?: A solar inverter is connected to solar panels through a direct current (DC) input from the panels, which is then converted into alternating current (AC) output by the inverter.

Q: How does a solar inverter handle electromagnetic interference?: A solar inverter handles electromagnetic interference (EMI) by incorporating various measures to reduce and mitigate its impact. These measures include using shielding materials, implementing proper grounding techniques, and utilizing filters to suppress EMI. Additionally, advanced inverters may employ digital signal processing techniques to minimize the effects of EMI on the solar power system.

Q: How does a solar inverter handle voltage rise in case of low load conditions?: A solar inverter handles voltage rise in case of low load conditions by using a feature called voltage regulation. It continuously monitors the voltage level and adjusts the power output accordingly to prevent any excessive rise in voltage. This helps maintain a stable and safe voltage level, even during low load conditions.

Q: Are there any safety risks associated with solar inverters?: Yes, there are potential safety risks associated with solar inverters. These risks can include electrical hazards, such as electric shock or fire, especially if the inverter is not installed or maintained correctly. Additionally, there is a possibility of arc flash incidents and potential exposure to high voltage DC electricity. It is important to follow proper installation and maintenance procedures, as well as adhere to safety guidelines provided by manufacturers and professionals, to mitigate these risks and ensure safe operation of solar inverters.

Q: What is the role of a power control unit in a solar inverter?: The role of a power control unit in a solar inverter is to regulate and control the flow of electricity between the solar panels and the grid. It ensures maximum power output from the solar panels by optimizing their performance and matching it with the electrical requirements of the grid. Additionally, it provides protection against overvoltage, overcurrent, and other electrical faults to ensure safe and efficient operation of the solar inverter system.

Q: What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?: Offline generally need energy storage, not to send energy to the Internet. Grid has no right to interfere.

Q: Can a solar inverter be used in areas with unstable grid power?: Yes, a solar inverter can be used in areas with unstable grid power. In fact, solar inverters are often used in such areas to provide a stable and reliable power supply. The inverter's ability to convert solar energy into usable electricity allows it to function independently of the grid power, ensuring a continuous power supply even during grid outages or fluctuations.
