The NMS Series PV + EV Charging Integrated Energy Solution is a holistic system composed of high-efficiency photovoltaic modules, intelligent charging piles, an energy storage unit, and a centralized management platform. It leverages advanced integration technology to realize complementary advantages of each component, delivering stable, efficient, and cost-effective energy services for commercial complexes.
1. High-Efficiency PV System: Maximizing On-Site Energy Generation
The PV module of the NMS Series adopts monocrystalline silicon technology with a conversion efficiency of up to 23.5%, significantly higher than the industry average of 19%-21%. Designed for commercial scenarios, the modules feature a lightweight and durable structure, suitable for installation on roofs, parking lot canopies, and building facades without affecting the original architectural functions. The system supports both "spontaneous self-consumption and surplus power grid feed-in" and "full self-consumption" modes, allowing commercial complexes to flexibly adjust based on local electricity policies and operational needs.
For example, a medium-sized commercial complex with a 10,000-square-meter roof can install a 1.5MW NMS PV system, generating approximately 160,000 kWh of clean electricity annually. This covers about 15% of the complex’s daily electricity demand, including lighting, air conditioning, and charging piles. By reducing reliance on grid power, the complex can cut annual electricity costs by 80,000 to 120,000 US dollars, while reducing carbon emissions by 120 tons per year—equivalent to planting 6,600 trees. The PV modules also serve as an additional protective layer for roofs and canopies, extending their service life by preventing direct sunlight and rain erosion.
2. Intelligent EV Charging Piles: Meeting Diversified Charging Needs
The NMS Series is equipped with a full range of EV charging piles, including DC fast chargers (60kW-180kW) and AC slow chargers (7kW-22kW), to meet the needs of different users such as shoppers, office workers, and residents. The charging piles adopt modular design and IP54 waterproof and dustproof rating, ensuring stable operation in outdoor commercial environments with high foot traffic. What sets them apart is the intelligent load balancing technology, which dynamically distributes power between the PV system, energy storage unit, and grid to avoid overload during peak charging periods.
The charging system is integrated with a mobile app and cloud platform, enabling users to complete reservation, payment, and charging status monitoring with a single click. For commercial complex operators, the platform provides real-time data on charging volume, power consumption, and revenue, facilitating refined management. During off-peak hours (e.g., late at night), the system can store low-cost grid power or surplus PV power in the energy storage unit, and use it for charging during peak hours—effectively reducing peak electricity costs and improving energy utilization efficiency.
3. Energy Storage Unit: Enhancing Energy System Resilience
A key highlight of the NMS Series solution is its integrated lithium-ion energy storage unit (with a capacity range of 100kWh-500kWh), which acts as a "energy buffer" for the entire system. It solves the intermittency and instability problems of PV power generation caused by weather changes, ensuring continuous power supply for critical loads such as emergency lighting, security systems, and core charging piles.
The energy storage unit supports grid-connected/off-grid dual-mode operation. In the event of grid outages due to natural disasters or equipment failures, it can quickly switch to off-grid mode within 10ms, providing emergency power supply for the complex’s key facilities. This not only enhances the energy system’s resilience but also ensures the safety of personnel and property. Additionally, the unit participates in demand response programs, helping the complex reduce peak load demand and earn subsidies from local power grids—creating an additional revenue stream.
4. Centralized Intelligent Management Platform: One-Stop System Control
The NMS Series is managed by a centralized intelligent platform that integrates PV generation monitoring, charging pile operation, energy storage management, and grid interaction. The platform uses big data and AI algorithms to analyze real-time energy flow, predict PV generation and charging demand, and optimize energy allocation strategies dynamically.
Operators can monitor the entire system’s operation status through a dashboard, including PV module efficiency, charging pile utilization, energy storage SOC (State of Charge), and energy consumption data. The platform also supports remote diagnosis and maintenance, automatically alerting technicians to faults such as abnormal charging or PV module damage—reducing maintenance costs and downtime. For large commercial complexes with multiple branches, the platform enables unified management of all energy systems, realizing standardized operation and cost control.
