NMS Series: An Efficient Power Generation Solution for PV Carport Projects
With the global promotion of renewable energy and the accelerating pace of green urban construction, PV carport projects have emerged as a typical integration of "energy conservation, environmental protection and practicality". As a new type of distributed photovoltaic application, PV carports not only realize the dual functions of vehicle shelter and solar power generation, but also form a "local generation and local consumption" green energy closed loop, which is widely used in residential communities, industrial parks, commercial plazas, railway stations and other scenarios. Different from traditional rooftop PV or ground PV systems, PV carport projects have unique operational characteristics and performance requirements for core equipment: affected by the shelter of vehicle bodies and surrounding buildings, the light conditions are complex and easy to produce partial shading; the load demand is flexible, involving both charging piles and daily power consumption; at the same time, they need to adapt to outdoor harsh environments and have high reliability. Against this backdrop, the NMS Series PV Inverter, with its dual core advantages of low startup voltage and wide power range, and a number of scenario-adaptive auxiliary functions, has become an efficient and reliable power generation solution for PV carport projects, breaking through the technical bottlenecks of traditional inverters in carport scenarios and empowering the high-quality development of PV carport projects.
To understand the core value of the NMS Series in PV carport projects, it is first necessary to clarify the unique technical challenges of PV carport power generation systems. As a comprehensive application combining photovoltaic power generation and transportation supporting facilities, the PV carport system has three prominent pain points in the process of operation. First, the light environment is unstable: the PV modules installed on the carport roof are easily shaded by vehicle bodies, adjacent buildings, trees and other obstacles, resulting in uneven output voltage of the modules and difficulty in stable power generation of the system. Second, the load demand is diverse and fluctuating: the PV carport needs to supply power to electric vehicle charging piles (including super charging piles and fast charging piles), and also needs to meet the power demand of auxiliary facilities such as lighting and monitoring in the carport. The load power varies greatly, requiring the inverter to have strong adaptability. Third, the operating environment is harsh: as an outdoor equipment, the inverter needs to withstand the test of high temperature, rain, strong wind, dust and other harsh weather, and its reliability and durability directly determine the stable operation of the entire PV carport project. The NMS Series PV Inverter is precisely designed for these pain points, integrating multiple advanced technologies to provide a targeted efficient power generation solution for PV carport projects.
The low startup voltage advantage of the NMS Series PV Inverter is the key to solving the problem of low energy utilization in PV carport scenarios with complex light conditions. Due to the particularity of the carport structure, the PV modules on the roof are often in a state of partial shading: for example, when vehicles are parked under the carport, the vehicle body will block part of the sunlight; in the morning and evening, the sunlight angle is low, and the surrounding buildings or trees will also form shading on the PV modules. Traditional PV inverters usually have a startup voltage of 80-100VDC, which can only start working when the PV module output voltage reaches the minimum startup standard under strong light. Once shaded, the module output voltage decreases, and the traditional inverter will shut down frequently or fail to start, resulting in serious waste of solar energy and low power generation efficiency of the PV carport.
In contrast, the NMS Series has optimized its internal circuit design and adopted advanced power management chips, reducing the minimum startup voltage to 45VDC—far lower than the industry average. This significant optimization enables the NMS Series to effectively capture weak solar energy, even when the PV modules are partially shaded and the output voltage is low, it can still start stably and maintain continuous power generation. Practice has proved that the NMS Series inverter can extend the daily working time of the PV carport system by 1-2 hours on average, especially in cloudy days, early mornings, late afternoons or seasons with short daylight hours. For example, in a commercial plaza PV carport project covering 20 parking spaces, the PV modules on the roof are often shaded by adjacent commercial buildings in the morning and evening. After adopting the NMS Series inverter, the system can still start generating electricity stably at 7:00 in the morning, while the traditional inverter can only start at 8:30; in the evening, the NMS Series can continue working until 18:00, while the traditional inverter shuts down at 16:30. This 2.5-hour extension of working time increases the daily power generation of the PV carport by 18%-22%, effectively improving the energy utilization rate and economic benefits of the project.
In addition, the NMS Series is equipped with advanced MPPT (Maximum Power Point Tracking) technology, which can cooperate with the low startup voltage advantage to further improve the power generation efficiency of PV carports under complex light conditions. The MPPT controller can real-time monitor the voltage and current output of each group of PV modules, automatically adjust to the optimal operating point, and extract the maximum possible power even when the modules are partially shaded. For PV carports with scattered module installation or uneven light reception, this technology can effectively solve the problem of "drag-down effect" caused by partial shading, ensuring that each group of modules can operate at the highest efficiency, and further maximizing the utilization of solar energy. This is particularly important for PV carport projects in urban areas, where shading is inevitable due to dense buildings and complex environments.
The wide power range of the NMS Series PV Inverter perfectly matches the diverse load demands and flexible system scales of PV carport projects, providing a one-stop power generation solution for carports of different sizes and types. PV carport projects vary greatly in scale, from small residential community carports with 5-10 parking spaces to large-scale industrial park or railway station carports with hundreds of parking spaces, and their power generation capacity and load demand differ significantly. The NMS Series covers a full power range from 1kW to 100kW, including small-power models (1kW-5kW) suitable for small residential carports, medium-power models (5kW-30kW) suitable for commercial plaza or enterprise parking lot carports, and high-power models (30kW-100kW) suitable for large-scale railway station or industrial park "light storage and charging" integrated carports, which can flexibly match the power demand of PV carports of different scales without the need for multiple inverters to be combined, reducing system installation costs, simplifying operation and maintenance, and improving system stability.
The small-power models (1kW-5kW) of the NMS Series are tailored for small residential community PV carports. Such carports usually have a small number of parking spaces, and the load is mainly electric vehicle charging piles for residents and auxiliary lighting in the carport. The small-power NMS Series inverter has a compact size, easy installation, and can be flexibly placed in the corner of the carport without occupying too much space. Its low startup voltage ensures that the system can generate electricity efficiently even when the carport is shaded by surrounding buildings or trees, stably supplying power to residential electric vehicle charging and carport lighting. For example, a residential community PV carport with 8 parking spaces adopts the NMS-3kW inverter, which can stably generate electricity under weak light, meet the daily charging needs of 8-10 electric vehicles, and feed excess power into the grid, bringing additional economic benefits to the community property and residents.
The medium-power models (5kW-30kW) of the NMS Series are mainly used in commercial plaza, enterprise parking lot or small-scale public facility PV carports. These carports have moderate scales, with 15-50 parking spaces, and the load includes electric vehicle charging piles, carport lighting, monitoring equipment, and even can supply power to the surrounding commercial facilities or office areas. The medium-power NMS Series inverter has strong load adaptability, which can flexibly adjust the output power according to the load changes, ensuring stable power supply to charging piles and other equipment. For example, in a enterprise parking lot PV carport with 30 parking spaces, the NMS-20kW inverter is adopted to power 15 fast charging piles and 20 sets of monitoring and lighting equipment. During the peak charging period (such as commuting time), the inverter can stably output high power to meet the simultaneous charging demand of multiple electric vehicles; during the low peak period, it can adjust the output power in real time, avoid energy waste, and optimize the energy allocation of the system. This flexible load adaptation capability fully meets the practical needs of commercial and enterprise PV carports.
The high-power models (30kW-100kW) of the NMS Series are designed for large-scale "light storage and charging" integrated PV carport projects, such as railway station parking lots, large industrial parks or airport carports. These projects usually have hundreds of parking spaces, integrate photovoltaic power generation, energy storage systems and super charging facilities, forming a green energy closed loop of "local generation, local storage and local use". The high-power NMS Series inverter adopts a modular design, which can be flexibly combined according to the actual scale of the PV carport, facilitating later expansion and maintenance. Its wide power range enables it to adapt to the large fluctuations in power output of large-scale PV arrays and the high-power demand of super charging piles, ensuring stable power supply to the entire system. For example, in a railway station "light storage and charging" integrated PV carport project covering 100 parking spaces, the total installed capacity of the PV system is 500kW, and 6 sets of NMS-80kW high-power inverters are adopted. The system not only supplies power to 34 charging piles (including 600kW super charging piles), but also configures a 215kWh energy storage system to store excess photovoltaic power, which can not only improve the self-consumption capacity of the system, but also use the peak-valley electricity price difference to reduce the operation cost of the project. The NMS Series inverter’s stable high-power output and flexible scalability provide a reliable guarantee for the efficient operation of such large-scale integrated projects.
In addition to the dual core advantages of low startup voltage and wide power range, the NMS Series PV Inverter also has a number of auxiliary advantages that are highly compatible with PV carport scenarios, further enhancing its reliability and practicality in outdoor carport environments. First, it has excellent environmental adaptability: the inverter adopts a high-quality aluminum alloy shell, which has good heat dissipation, dustproof and waterproof performance, and can operate stably in harsh outdoor environments such as high temperature, high humidity, strong wind and dust storms. Its operating temperature range is -30℃ to 60℃, which can adapt to extreme climate conditions in various regions, whether it is the hot summer in southern China or the cold winter in northern China, it can maintain stable performance. This is particularly important for PV carports, where inverters are placed outdoors for a long time and are vulnerable to the impact of harsh weather.
Second, it supports grid-tied and off-grid dual working modes, which can be flexibly switched according to the actual needs of PV carport projects. For most urban PV carports, they are connected to the public power grid to ensure stable power supply when solar energy is insufficient; for remote areas or temporary PV carports (such as construction site carports), the off-grid mode can be adopted to realize independent power supply, which is flexible and convenient. In addition, the NMS Series has a complete set of protection functions, including overvoltage protection, undervoltage protection, overcurrent protection, short-circuit protection, over-temperature protection and leakage protection, which can effectively protect the inverter, PV modules, charging piles and other equipment from damage, and avoid safety accidents such as short circuits or fires caused by equipment failure, ensuring the safe and stable operation of the PV carport system.
The intelligent performance of the NMS Series also provides strong support for the efficient operation and convenient maintenance of PV carport projects. The inverter is equipped with an intuitive LCD display and supports WIFI/GPRS remote monitoring, allowing project operators to real-time monitor the operation status, power generation, load consumption and fault information of the PV carport system through a smartphone app or computer, regardless of their location. For large-scale PV carport projects with scattered inverter installation, this remote monitoring function can greatly reduce the workload of on-site inspection, improve the efficiency of operation and maintenance, and timely detect and solve potential faults. In addition, the NMS Series has a one-key reset function, which can quickly solve minor faults without professional technical personnel, further reducing the operation and maintenance cost of the project.
Practical application cases further verify that the NMS Series is an efficient and reliable power generation solution for PV carport projects. In a railway station "light storage and charging" integrated PV carport project in East China, the project covers 120 parking spaces, integrates photovoltaic power generation, 250kWh energy storage system and 40 charging piles, and adopts 8 sets of NMS-75kW high-power inverters. Due to the complex surrounding environment of the railway station, the PV modules on the carport roof are often shaded by nearby buildings and passing vehicles. The low startup voltage and advanced MPPT technology of the NMS Series ensure that the system can start stably and generate electricity efficiently even under partial shading conditions. The annual power generation of the project reaches 600,000 kWh, which can meet 40% of the charging demand of the carport and 30% of the power demand of the railway station’s auxiliary facilities, reducing carbon emissions by 500 tons per year and achieving significant economic and environmental benefits. In a residential community PV carport project in South China, 10 sets of NMS-3kW inverters are adopted to supply power to 50 parking space charging piles and community public lighting. The system operates stably all year round, with an annual power generation of 80,000 kWh, which not only meets the daily charging needs of residents, but also reduces the community’s reliance on the public power grid, bringing good economic benefits to the community.
Against the backdrop of the global photovoltaic inverter market fluctuations, the NMS Series PV Inverter still maintains strong competitiveness in the PV carport field with its unique scenario adaptation advantages. According to industry reports, after reaching a record high in 2024, global photovoltaic inverter shipments are expected to decline to 577GWac in 2025 (a decrease of 2%) and further to 523GWac in 2026 (a decrease of about 9%), reflecting uncertainties in major markets. However, with the acceleration of global green travel and the promotion of new energy vehicle industry, the demand for PV carport projects is growing rapidly, and the demand for high-performance inverters suitable for carport scenarios is also increasing. The NMS Series, with its dual core advantages of low startup voltage and wide power range, and its excellent environmental adaptability and intelligent performance, has won wide recognition in the PV carport market, and its application scope is constantly expanding.
Beyond its technical and practical advantages, the NMS Series PV Inverter also embodies the concept of sustainable development, aligning with global efforts to reduce carbon emissions and promote green travel. PV carports, as an important carrier of distributed photovoltaic energy, can effectively utilize idle parking space resources to generate clean energy, reduce reliance on fossil fuels, and mitigate climate change. The NMS Series, by improving the power generation efficiency and stability of PV carport projects, helps to promote the popularization of PV carports, accelerate the integration of renewable energy and transportation, and contribute to the construction of green cities and low-carbon society. For enterprises and institutions, adopting the NMS Series as the power generation solution for PV carport projects can not only reduce energy costs, but also enhance environmental protection image, achieving a win-win situation of economy and environmental protection.
In conclusion, the NMS Series PV Inverter, with its dual core advantages of low startup voltage and wide power range, and a number of scenario-adaptive technologies, perfectly solves the technical pain points of PV carport projects such as complex light conditions, diverse load demands and harsh operating environments, and has become an efficient, reliable and cost-effective power generation solution.
