How do I choose a solar inverter size?
To calculate the ideal inverter size for your solar PV system, you should consider the total wattage of your solar panels and the specific conditions of your installation site. The general rule is to ensure the inverter’s maximum capacity closely matches or slightly exceeds the solar panel array’s peak power output.
How much solar power can a 5kw inverter produce?
Under the Clean Energy Council rules for accredited installers, the solar panel capacity can only exceed the inverter capacity by 33%. That means for a typical 5kW inverter you can go up to a maximum of 6.6kW of solar panel output within the rules.
Which solar inverter should I Choose?
The choice between a single-phase or three-phase inverter will depend on the size of your solar array and your electrical service. Generally, single-phase inverters are suitable for smaller solar installations (up to around 10 kW), while three-phase inverters are necessary for larger systems.
Should a solar inverter be oversized?
However, slight over-sizing of the solar panels compared to the inverter capacity (up to 133% under certain guidelines) can sometimes yield better overall efficiency due to the variable nature of solar irradiation throughout the day. The ratio for inverter sizing often depends on specific system requirements and local regulations.
How many solar panels can one microinverter serve?
Microinverters are usually placed under each solar panel, in a ratio of one microinverter for every 1-4 panels. A microinverter is a device that converts the DC output of solar modules into AC that can be used by the home. As the name suggests, they are smaller than the typical solar power inverter, coming in at about the size of a WiFi router.
What size inverter for a 5 kW solar array?
For example, a 5 kW solar array typically requires a 5 kW inverter. However, factors like derating, future expansion plans, and the array-to-inverter ratio influence the optimal inverter size. Most installations slightly oversize the inverter, with a ratio between 1.1-1.25 times the array capacity, to account for these considerations.

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.
