20~30KVA Online Low Frequency 3 in 3 Out Double Conversion UPS

 

 

1. Wide range of input voltage

The UPS can offer normal and stable service voltage under its input voltage range. When the input voltage is out of its range the machine will switch to battery mode automatically to keep the output power in order to protect the equipment, such as computers, ensure they will not be damaged by the over high or over low voltage, users can continue the operation of equipment for a while or save the data on computers while the power network is abnormal.

 

2. Wide range of AVR(Automatic voltage regulation)

In the product’s input voltage range and under 3 steps of intelligent AVR function, it can provide a stable output voltage.

 

3. Automatic self detection when UPS on(LED).

Before the UPS on, red, yellow, blue LED will light up two times by cycle turns, after self detection UPS switch to AC mode/battery mode or working mode. 

 

4. Silence function

In the "battery mode", shortly press the switch to turn off the buzzer. But the battery is about to run out or the load is too heavy, the buzzer sound cannot be muted.

 

5. Overload protection

In the battery mode, output voltage turn down correspondingly when it is overload, after the capacity of load is lower than the rated power then output voltage will back to rated value, it ensures the UPS will not shut down by abrupt overload which caused by surging current during the computer is working and other equipment is added.

 

6. Short circuit protection

When the mis-operation caused the load short circuit or computer failure (such as power tube breakdown of switch) cause short circuit, the UPS will shutdown automatically for protection.

 

7. The low current switch

This UPS adopts low current switch to extend the service life which is longer than conventional battery and high current switch in AC current path.

 

8. Automatic charging

There are two charging mode, charging time is faster than ordinary charging mode, higher efficiency, and greatly prolonging the service life of the battery.

 

9. With a bypass output

Independent bypass output socket for external printers or scanners of computer peripherals, with surge protection of the load.

Q:How does a solar inverter handle voltage regulation during load changes?
A solar inverter handles voltage regulation during load changes by continuously monitoring the load and adjusting the inverter's output voltage accordingly. It uses various control mechanisms to maintain a stable voltage output, such as pulse width modulation (PWM) and maximum power point tracking (MPPT) algorithms. These algorithms enable the inverter to regulate its output voltage to match the load requirements, ensuring a consistent and reliable power supply.
Q:Can a solar inverter be used with a solar tracker system?
Yes, a solar inverter can be used with a solar tracker system. A solar inverter is responsible for converting the direct current (DC) produced by solar panels into alternating current (AC) that can be used to power electrical devices. A solar tracker system, on the other hand, is designed to maximize the efficiency of solar panels by orienting them towards the sun throughout the day. By using a solar inverter in conjunction with a solar tracker system, the generated electricity can be efficiently converted and used for various applications.
Q:Can a solar inverter be used with different solar panel brands?
Yes, a solar inverter can be used with different solar panel brands as long as they are compatible in terms of voltage, current, and power ratings. The inverter should support the specific voltage and power requirements of the solar panels for optimal performance and efficiency.
Q:Can a solar inverter be integrated with a smart home system?
Yes, a solar inverter can be integrated with a smart home system. This integration allows for monitoring and controlling the solar energy production, as well as optimizing energy usage and managing the overall efficiency of the system.
Q:Can a solar inverter be used with solar-powered electric vehicle charging stations?
Yes, a solar inverter can be used with solar-powered electric vehicle charging stations. A solar inverter is responsible for converting the DC power generated by solar panels into AC power that can be used to charge electric vehicles. By using a solar inverter, the solar energy harvested from the panels can be efficiently utilized to charge EVs, making it an environmentally-friendly and sustainable option for charging stations.
Q:How does a solar inverter contribute to reducing carbon emissions?
A solar inverter plays a crucial role in reducing carbon emissions by converting the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be used to power homes and businesses. By enabling the integration of solar power into the electrical grid, solar inverters help to replace conventional fossil fuel-based electricity generation, which is a major source of carbon emissions. This shift towards clean and renewable solar energy helps to reduce carbon emissions and mitigate the adverse effects of climate change.
Q:Are there any ongoing maintenance requirements for a solar inverter?
Yes, there are ongoing maintenance requirements for a solar inverter. Regular cleaning of the solar panels to remove dust and debris is necessary to maintain optimal performance. Additionally, inspections and tests of the inverter's components, such as cables and connections, should be conducted periodically to ensure everything is functioning properly. Monitoring the inverter's performance and addressing any issues promptly is also crucial for long-term maintenance.
Q:What is the role of a galvanic isolation transformer in a solar inverter?
The role of a galvanic isolation transformer in a solar inverter is to provide electrical isolation between the input (solar panels) and the output (power grid). This isolation helps in preventing any electrical noise, surges, or ground loops from affecting the solar inverter or the power grid, ensuring safe and reliable operation. Additionally, the galvanic isolation transformer helps in maintaining the required level of insulation and protection, complying with safety standards and regulations.
Q:Can a solar inverter be used with a solar-powered water pumping system?
Yes, a solar inverter can be used with a solar-powered water pumping system. A solar inverter is responsible for converting the direct current (DC) electricity generated by the solar panels into alternating current (AC) electricity, which is required to power the water pump. Therefore, a solar inverter is a crucial component in ensuring the efficient operation of a solar-powered water pumping system.
Q:What are the key differences between a central inverter and a string inverter?
The key differences between a central inverter and a string inverter lie in their design and functionality. A central inverter is a single large inverter that is typically installed at a central location in the solar power system. It receives the DC power generated by multiple solar panels connected in series, and then converts it into AC power for use in the electrical grid. Central inverters are more suitable for large-scale solar installations as they can handle higher power outputs. On the other hand, a string inverter is a smaller inverter that is installed close to the solar panels. It works by converting the DC power generated by a string of panels, typically 8 to 12, into AC power. String inverters are commonly used in residential or smaller commercial solar installations. One notable difference is the location of the inverters. Central inverters are typically installed in a dedicated room or enclosure, away from the solar panels, whereas string inverters are generally mounted either on the wall or directly on solar panel mounting racks. Another difference is the impact of shading or panel malfunction. In a central inverter system, if one panel is shaded or malfunctions, it affects the output of the entire string of panels. In contrast, with a string inverter system, the impact is limited to only the affected string, allowing other strings to continue generating power efficiently. Additionally, string inverters offer better monitoring capabilities as they can provide real-time data for each individual string of panels, allowing for easier troubleshooting and maintenance. Central inverters, on the other hand, provide a single output value for the entire solar array. Overall, the choice between a central inverter and a string inverter depends on the scale of the solar installation, the available space, and the specific requirements of the project.
