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 grid connection feature in a solar inverter?: The role of a grid connection feature in a solar inverter is to allow the solar power system to connect and interact with the electrical grid. This feature enables the solar inverter to convert the direct current (DC) produced by the solar panels into alternating current (AC) that is compatible with the electrical grid. It ensures that excess solar energy can be fed back into the grid, allowing the system owner to receive credit or payments for the electricity generated. Additionally, the grid connection feature allows the system to draw power from the grid when solar energy is insufficient, ensuring a reliable and continuous power supply.

Q: What is the role of a maximum power control feature in a solar inverter?: The role of a maximum power control feature in a solar inverter is to optimize the energy output of the solar panels by constantly tracking the maximum power point (MPP) of the solar array. This feature adjusts the operating conditions of the inverter to ensure that it operates at the highest possible efficiency, maximizing the energy harvested from the solar panels and improving overall system performance.

Q: Photovoltaic grid-connected inverter without DC emc how will happen: Solar photovoltaic power generation technology is the use of solar cells, the photovoltaic effect of semiconductor materials, solar radiation can be directly converted into a new type of power generation system, solar energy is a radiant energy, solar power means --- to direct conversion of sunlight Into electricity,

Q: How does a solar inverter handle ground fault protection?: A solar inverter handles ground fault protection by continuously monitoring the electrical currents flowing between the solar panels and the grid. If it detects any abnormal current leakage to the ground, it quickly shuts down the system to prevent any potential electrical hazards or damage. This ensures the safety of both the equipment and personnel working with the solar installation.

Q: Can a solar inverter be used with different types of monitoring systems?: Yes, a solar inverter can typically be used with different types of monitoring systems. Most modern solar inverters come with built-in communication interfaces that allow for seamless integration with various monitoring systems. These systems can range from basic monitoring apps provided by the inverter manufacturer to more advanced third-party monitoring platforms. As long as the monitoring system supports the communication protocol of the solar inverter, it can be used to monitor and manage the performance of the solar power system.

Q: Can a solar inverter be used with a solar-powered water pump?: Yes, a solar inverter can be used with a solar-powered water pump. A solar inverter converts the direct current (DC) generated by solar panels into alternating current (AC) that can be used to power various electrical devices, including water pumps. This allows the solar panels to directly power the water pump, making it an efficient and sustainable solution for water pumping applications.

Q: What are the safety certifications for a solar inverter?: Some common safety certifications for solar inverters include UL 1741, IEC 62109, and CSA C22.2 No. 107.1. These certifications ensure that the inverters meet specific safety standards and requirements, such as protection against electrical shock, fire hazards, and grid stability.

Q: What is the difference between a central inverter and a string inverter?: A central inverter is designed to convert the DC power generated by multiple solar panels into AC power at a central location. It usually handles larger power capacities and requires professional installation. On the other hand, a string inverter is installed near the solar panels and converts the DC power generated by a string or series of panels into AC power. It is typically used in smaller-scale solar installations and is easier to install and maintain.

Q: How does a solar inverter synchronize with the electrical grid?: A solar inverter synchronizes with the electrical grid by constantly monitoring the grid's voltage and frequency. It adjusts its own output voltage and frequency to match those of the grid, ensuring seamless integration and safe operation. This synchronization process allows the solar inverter to feed power into the grid and maintain grid stability.

Q: How do you choose the right size of solar inverter for a system?: When choosing the right size of solar inverter for a system, it is important to consider the total capacity of the solar panels and the expected power output. The inverter should have a capacity that matches or slightly exceeds the maximum power output of the panels to ensure optimal efficiency. Additional factors such as the type of grid connection and any future expansion plans should also be taken into account. Consulting with a professional solar installer or conducting a thorough system assessment can help determine the appropriate size of the inverter for a given solar system.
