What is inverter communication?
Inverter communications refer to the exchange of information between inverters and other devices, such as monitoring and control systems. Inverters are electronic devices that convert direct current (DC) to alternating current (AC), which is necessary for various applications, including renewable energy systems and industrial automation.
Why do HVAC systems use inverters?
HVAC systems perform best and save energy when inverters and components communicate well. Inverters are used in HVAC systems to control motors, compressors, and fans, which are crucial to efficient heating and cooling. Inverter communications enable real-time HVAC system monitoring and control, reducing energy consumption and costs.
Why do inverters use Ethernet?
Using Ethernet as the communication interface allows inverters to transmit large amounts of data over long distances with minimal data loss, crucial for efficient data exchange in smart grid systems. It also enables remote monitoring and control of inverters, improving system automation and control.
How do inverter controllers work?
The controller of each inverter resource continuously tracks its own angle as a reference. If the system is in a stable state, the controller updates the reference value of the angle to the present value.
Why is Modbus important for inverters?
By enabling seamless data exchange between devices, Modbus can help enhance the overall efficiency and performance of inverters in different industrial settings. The CAN bus (Controller Area Network) Protocol plays an essential role in inverter communications.

High - Capacity Lithium - Ion Energy Storage Systems
Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.
Smart Hybrid Inverters
Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.
Portable Solar Power Stations
Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit. Ideal for outdoor enthusiasts, campers, and those in need of emergency backup power, these stations can charge various electronic devices like smartphones, laptops, and even small appliances. Their portability and ease of use make them a convenient choice for anyone who wants to access clean energy wherever there's sunlight, providing a reliable power source in remote locations or during power outages.
Distributed Photovoltaic Power Station Solutions
Our distributed photovoltaic power station solutions are tailored for various applications, from small communities to large industrial complexes. By distributing solar panel installations across multiple locations, we can make better use of available space and increase the overall energy generation capacity. These solutions are designed with high-performance components and integrated monitoring systems to ensure efficient operation, easy maintenance, and maximum energy yield. They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
