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:How does a grid-tied solar inverter function?: A grid-tied solar inverter functions by converting the direct current (DC) generated by solar panels into alternating current (AC) that can be used to power appliances and feed back into the electrical grid. It synchronizes the AC power output with the grid's frequency and voltage, allowing excess electricity produced by the solar panels to be sent back to the grid, earning credits or reducing the homeowner's energy bill. It also ensures the system's safety by monitoring grid conditions and automatically shutting down during power outages.

Q:Can a solar inverter be used with smart home systems?: Yes, a solar inverter can be used with smart home systems. Smart home systems are designed to integrate and control various devices, including solar inverters, to optimize energy usage and manage power generation. By connecting a solar inverter to a smart home system, users can monitor and control their solar power production, track energy consumption, and even automate energy-saving actions based on real-time data. This integration enhances the efficiency and functionality of both the solar inverter and the smart home system.

Q:Can a solar inverter be used with different types of solar panel mounting systems?: Yes, a solar inverter can be used with different types of solar panel mounting systems. The solar inverter is designed to convert the direct current (DC) generated by the solar panels into alternating current (AC) that can be used to power appliances and electrical devices. Regardless of the mounting system, as long as the solar panels are connected to the solar inverter, it can efficiently convert the generated energy for use.

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:Can a solar inverter be connected to a home automation system?: Yes, a solar inverter can be connected to a home automation system. This integration allows homeowners to monitor and control their solar power generation and consumption remotely through their home automation system. It provides real-time data on energy production, allows for scheduling and optimizing energy usage, and enables the automation of various appliances and devices based on solar power availability.

Q:Can a solar inverter be used in conjunction with a backup generator?: Yes, a solar inverter can be used in conjunction with a backup generator. In a hybrid system, the solar inverter intelligently manages the power supply, utilizing solar energy when available and seamlessly switching to the backup generator during times of low solar production or high energy demand. This setup ensures continuous power supply even during cloudy days or power outages.

Q:How do you calculate the maximum power point voltage for a solar inverter?: To calculate the maximum power point voltage for a solar inverter, you need to consider the voltage at which the solar panel generates the highest power output. This can be determined by using the voltage-current (V-I) curve of the solar panel and finding the point where the product of voltage and current is maximum. By analyzing this curve, the maximum power point voltage can be identified, which is crucial for optimizing the performance of a solar inverter.

Q:How does a solar inverter synchronize with the electrical grid?: A solar inverter synchronizes with the electrical grid through a process called grid synchronization. This involves the inverter constantly monitoring the voltage and frequency of the grid and adjusting its own output accordingly to match the grid's parameters. Once the inverter's output matches the grid's voltage and frequency, it can seamlessly feed the solar-generated electricity into the grid, ensuring safe and efficient integration of solar power into the existing electrical infrastructure.

Q:Can a solar inverter be used with solar-powered electric fences?: Yes, a solar inverter can be used with solar-powered electric fences. Solar inverters are used to convert the direct current (DC) produced by solar panels into alternating current (AC) that can be used to power various electrical devices, including electric fences. By connecting a solar inverter to the solar panels of a solar-powered electric fence system, the DC power generated by the panels can be converted into the AC power required to operate the electric fence.

Q:What are the main components of a solar inverter?: The main components of a solar inverter typically include the DC input, MPPT (Maximum Power Point Tracking) system, inverter circuit, transformer, and AC output.
