Why do we need Island power systems?
Why Island Power Systems? The experience we cumulated from the island grids could forge a path of transforming a larger power grid into a highly renewable future. Variability and uncertainty from renewables: Maintain the balance between production and consumption. Oscillations caused by inverter-based resources (IBRs).
How does a solar inverter work if the grid goes down?
If the grid goes down, your solar system is designed to turn off automatically to ensure the safety of utility workers fixing power lines. On the other hand, if you're completely off the grid, you're already on your own power island. Your islanding solar inverter works independently from the power grid.
Can You Turn your home into an energy island?
However, much like islands are forced to be self-sufficient if you install a battery with islanding capabilities, you can turn your home into an "energy island." As a result, islanding allows you to keep your home powered regardless of what's occurring on the rest of the grid, including during weather-related outages.
How does a solar inverter work during a power outage?
With a safe solar island system, the inverter assumes a highly complex but crucial role during a power outage: First, your inverter completely removes your home from the grid to fulfill anti-islanding requirements. Your inverter then uses a transfer switch to connect your home directly with the solar power system in island mode.
Can your home be a solar energy island?
However, your home can be a solar energy island with renewable energy available during a power outage or blackout. Integrating a solar inverter with island mode and battery storage will give you this capability while maintaining a connection to the grid.
How does a grid-tie inverter work?
Grid-tie inverters know when and when not to deliver power, and they will synchronize power delivery with the grid. This quick and constant process allows your home to have all the power it needs when it needs it, and it will remove your system from the grid when anti-islanding is needed.
Featured Solar Products
High - Efficiency Photovoltaic Panels
Our photovoltaic panels are at the forefront of solar technology. With advanced cell designs and high - quality materials, they offer exceptional energy conversion rates, allowing you to maximize your solar energy harvest. Whether installed on a residential rooftop or a large - scale solar farm, these panels are built to last, withstanding harsh weather conditions and providing reliable performance for decades.
Advanced Monocrystalline Solar Panels
These advanced monocrystalline solar panels are crafted from single-crystal silicon, which endows them with outstanding electrical properties. 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.
