What is high-voltage control system (distribution voltage stabilization system)?
High-voltage control system (Distribution voltage stabilization system) controls voltage using LRT, SVR, SVC, PCS and storage battery in high-voltage network and cooperating with multiple low-voltage control systems. High-voltage control system indicates specified power flow at the connection point to low-voltage network.
How sapv inverter is controlled?
The inverter of the SAPV system’s inverter is controlled with the sliding mode controller for obtaining the required PWM pulses. For both systems, the phase locked loop generates a corresponding angle with respect to the instantaneous output load voltage. 3.1. Controllers for hybrid source microgrid systems
How does a PV panel affect a sapv system?
The SAPV system will be affected due to the short circuit current of the pv panel (defined by the irradiance and temperature) and the load voltages. The control signal u is generated by the SMC based on the PV current and voltage. The SMC derives both the PV voltage and current to construct the switching function.
What is a solar cell in a photovoltaic system?
The solar cell is the basic component of a photovoltaic (PV) system. The cells are formed in parallel or series to produce the necessary current, voltage, and high power that forms a PV array. Each solar cell has a p–n junction of semiconductor materials, similar to a diode.
Why do solar inverters need a SMC controller?
Since the weather conditions affect the solar output, the constant dc needs to be maintained and maximized effectively using the SMC controller for the boost converter. Also, the SMC controller stabilizes the single-phase inverter’s output voltage and frequency with properly produced PWM pulses.
How VSI based sliding mode controller works?
The output of the DC–DC converter is connected to VSI with PWM based sliding mode controller in the final stage, which provides 1 ϕ power to the isolated 1 ϕ AC loads. The constant voltage and frequency at the inverter’s output are obtained using the sliding mode controller even under the variable loading pattern.
Featured Solar Products

They have a higher efficiency in converting sunlight into electricity compared to other types of panels. Their sleek appearance also makes them a popular choice for both residential and commercial installations. Moreover, they are durable and can maintain stable performance under various environmental conditions, ensuring a long lifespan and excellent return on investment.
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.
