How to connect an inverter to a grid?
4.4.1 AC Side Requirements Before connecting the inverter to the grid, ensure the grid voltage and frequency comply with requirements, for which, refer to Specification. Otherwise, contact the electric power company for help. Connect the inverter to the grid only after getting an approval from the local electric power company.
What should I do before starting my inverter?
Safety First: Before starting, turn off the main power supply and wear proper safety gear, such as gloves and goggles. Our inverter integrates Type II Surge Protection Devices (SPD) on both the AC and DC sides, providing robust protection against surges from lightning or grid fluctuations. Proper installation ensures system reliability and safety.
How do you mount a solar inverter?
Proper mounting not only ensures safe and stable operation but also allows the inverter to perform at peak efficiency. Wiring the Inverter: Connect the DC input from the solar panels to the inverter. Most inverters have clearly marked terminals for DC input.
How do you insulate a DC inverter?
Do not insert or pull the AC or DC terminals when the inverter is in operation. To completely insulate the equipment, turn of the DC switch and AC breaker, and disconnect the DC and AC terminals.
How do you install an inverter?
The inverter is best installed at eye level. This facilitates maintenance and allows the best visibility of product label, warnings, and LCD display. Install the inverter vertically or with a backward tilt within 15°. The inverter should not be tilted sideways. Do not install the inverter horizontally.
How to adjust a power inverter?
Turn on the DC switch, and set safety country according to the local regulation. Turn on the AC breaker. Check that the inverter functions normally. It is possible to adjust special setpoints such as trip points, trip times, reconnect times, active and inactive QU curves and PU curves. These are only adjustable through specific software.
Featured Solar Products

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.
