Why should PV generators be integrated into the grid?
With the increased integration of PV generators into the grid, the system operators start to require PV generators have capabilities to stay online during the fault, and provide the active power and the reactive power supports when being required to do so.
What is included in the off-grid PV power systems installation guideline?
system components are contained in the Off-grid PV Power Systems Installation Guideline. The relevant sections are referred to below and this section only highlights the installation of the fuelled generator and any additional req rate the generator into an Off-grid PV power system installation.15.1 Array InstallationRefer to section 5
How is a PV generator modeled in a power system steady state study?
A PV generator is modeled as a constant active power and reactive power source in power system steady state studies. When PV generation changes due to the ambient environment, the power system steady state studies do not investigate the transients of the power system caused by the change in PV generation.
What causes sustained power oscillations in photovoltaic energy storage system?
As a result, sustained power oscillations occur after the short-circuit failure in the photovoltaic energy storage system. The synchronous power continues to oscillate for more than 15 s even after the short-circuit fault is cleared, which seriously threatens the system security.
How does a PV generator work?
By controlling the instantaneous three-phase inverter output voltages v a, v b and v c, the PV generator controls the active power output and the reactive power interchanges with the external grid.

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.
