What size solar inverter do I Need?
Matching Your Inverter Size to Your Solar Panel System A good rule of thumb is that your inverter should be sized to handle 80-100% of your total solar panel capacity. For a 5kW solar panel system, a 4kW to 5kW inverter is typically recommended. For a 6kW system, a 5kW to 6kW inverter would be most appropriate.
How to choose a solar inverter?
If you intend to expand your solar power system in the future, possibly by adding more panels or a battery storage system, consider choosing a larger inverter or a hybrid inverter. These options can accommodate additional capacity and support your energy goals. 6. Checking Inverter Efficiency Ratings
Why is sizing a solar inverter important?
Correct sizing of a solar inverter is crucial. The wrong inverter capacity will weaken the performance of the solar panel system. The inverter has to be able to deal with the amount of energy it’s getting from the panels. Inverter sizes are measured in watts (W) or kilowatts (kW) – units of a thousand watts – the same as solar panels.
Is there a difference between inverter size and solar panel capacity?
However, this should always be within the recommended ratio. This is the reason why you may see a ‘mismatch’ between inverter size and solar panel capacity – for example, a 6.6kW system advertised with a 5kW inverter.
How do you calculate solar inverter size?
An important consideration in calculating inverter size is the solar panel system:inverter ratio. This is the direct current capacity of the solar array divided by the maximum alternating current output of the inverter. For example, a 3kW solar panel system with a 3kW inverter has an array-to-inverter ratio of 1.0.
How much power does a solar inverter produce?
Using the example of ten 300-watt panels, your total power output is 3,000 watts. Solar inverters have an efficiency curve, which shows how efficiently they convert DC power from the solar panels into AC power for your home. In general, look for an inverter with an efficiency rating above 95%.
Featured Solar Products

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.
