As a core infrastructure underpinning modern societal production, operations, and public welfare, the stability, cost-effectiveness, and sustainability of electricity supply directly shape the quality of socio-economic development. At present, issues such as power shortages and production curtailments, volatile electricity prices, and frequent outages continue to constrain progress across multiple sectors, placing increasingly stringent demands on the energy‑security system. Ruisu Intelligent Technology, a full‑chain manufacturer of charging and energy‑storage equipment, is deeply engaged in the research, development, and application of multi‑energy complementary technologies integrating solar, storage, and diesel power. Guided by the design philosophy of “solar priority, storage regulation, and diesel backup,” the company leverages intelligent coupling and coordinated operation among photovoltaic systems, energy‑storage units, and diesel generators to build highly reliable, economically efficient, and widely adaptable hybrid energy systems, offering tailored solar‑storage‑diesel multi‑energy solutions for diverse industries.


01

Precise adaptation across all scenarios, with customized solution applications.

Based on varying grid‑coverage conditions, load characteristics, and operational objectives, the Ruisu intelligent solar‑storage‑diesel multi‑energy complementary system delivers comprehensive adaptability, providing tailored energy‑security solutions across diverse sectors. Specific application scenarios are as follows:

1. Remote areas with no or weak network coverage: Establish an independent and reliable power supply system.

For remote mountainous areas, islands, agricultural and pastoral regions, border outposts, and other locations without grid access—along with factories, mining sites, and overseas areas facing power shortages where grid extension is inadequate—the system delivers autonomous energy supply in the form of standalone microgrids, replacing or supplementing conventional large-scale grids. During daylight hours, photovoltaic generation directly powers loads and charges energy storage; at night or during overcast or rainy conditions, stored energy discharges to ensure continuous power supply. In the event of prolonged extreme weather, a diesel generator automatically starts up to provide backup and replenish the energy reserves, thereby fully addressing issues of unavailability and instability in power supply and ensuring reliable electricity for both production and daily life.

2. Critical Infrastructure: Strengthening the Security Barrier for Uninterrupted Power Supply

Critical infrastructure such as hospitals, data centers, communication base stations, and fire stations demand exceptionally high power‑supply continuity, with availability requirements of at least 99.99%. The Ruisu intelligent photovoltaic–storage–diesel system serves as a high‑grade emergency backup power source, enabling seamless switching within ≤200 ms in the event of a utility‑grid failure—far faster than conventional UPS systems—thereby effectively preventing equipment downtime, data loss, and risks to life and property. When the duration of a power outage exceeds the storage system’s autonomy, the diesel generator automatically starts, providing dual redundancy and ensuring uninterrupted operation of critical business functions.

3. Temporary Construction Scenarios: Providing Flexible and Efficient Mobile Power Solutions

Construction sites for railways, highways, and tunnels, as well as temporary operation areas at mines and oilfields, are characterized by dispersed work locations, high mobility, and challenging grid‑connection conditions. Traditional diesel‑generator‑based power supply systems suffer from high costs and substantial carbon emissions. Ruisu Intelligent addresses these challenges with a modular, containerized “range‑extended power‑supply unit,” enabling plug‑and‑play deployment and flexible relocation in line with construction progress. This solution significantly reduces diesel consumption—case studies show savings of up to 710,000 liters—while cutting pollutant emissions, precisely matching load‑variation demands across different construction phases, and enhancing both the economic efficiency and environmental sustainability of temporary power provision.

4. Industrial and Commercial Sectors: Achieving Optimization of Electricity Costs and Enhancement of Energy Efficiency

Industrial and commercial settings—such as manufacturing plants, mixed‑use complexes, and large industrial parks—are characterized by high energy intensity and pronounced time‑of‑use price differentials. The system prioritizes optimizing electricity costs and achieves efficient energy utilization through arbitrage between peak and off‑peak tariffs: during peak periods, it prioritizes dispatching solar generation and discharging energy storage to reduce grid‑purchased power; during off‑peak periods, it draws grid power to charge the storage system, thereby smoothing load peaks and valleys and significantly lowering enterprise electricity expenses. Moreover, in the event of a sudden grid outage, the system ensures uninterrupted operation of critical production lines and core equipment, minimizing losses from production stoppages.

Intelligent Collaboration Mechanism: Standardizes workflows and ensures efficient system operation.

The Ruisu Intelligent Multi‑Energy Complementary System integrating solar, storage, and diesel power comprises distributed photovoltaic modules, an energy storage unit, a diesel generator, load terminals, and an intelligent monitoring and energy management system (EMS). By establishing a clear hierarchical energy flow and employing dynamic control strategies, the system enables coordinated operation among its components, ensuring stable and efficient energy supply. The specific operational mechanism is as follows:

1. Core Energy Flow Logic

The system adheres to a three-tier energy dispatch priority: At the first level, photovoltaic (PV) generation takes precedence, with PV power directly supplying the load; at the second level, energy storage is used for regulation and balance—when PV output exceeds load demand, excess energy charges the storage unit, while during periods of insufficient PV generation or sudden load spikes, the storage unit discharges to provide additional power; at the third level, a diesel generator serves as a backup—when the storage unit’s state of charge falls below a predefined safety threshold, the diesel generator automatically starts up to supply power and simultaneously replenish the storage unit. In grid‑connected operation mode, the system further integrates grid‑time‑of‑use pricing signals: during off-peak hours, it purchases electricity from the grid to charge the storage, and during peak periods or grid‑demand‑response phases, it releases stored energy, thereby achieving coordinated, optimized operation with the grid.

2.  Dynamic Mode Switching

Based on the state of charge (SOC) of the energy storage system, photovoltaic power forecast data, and real-time electricity price signals, the energy management system (EMS) automatically switches operating modes: when the energy storage has sufficient capacity and photovoltaic generation meets load demand, the system transitions to a standalone mode centered on energy storage, ensuring stable voltage and frequency; when the storage SOC falls below a safety threshold, it shifts to a diesel‑generator‑dominated standalone mode, maintaining power supply while simultaneously charging the storage unit. In grid‑connected operation, the system dynamically adjusts its charging and discharging strategy in response to real-time prices, maximizing both economic efficiency and social benefits.

Multi‑architecture Design: Adapts to Diverse Requirements and Enhances Overall System Performance

To accommodate the load characteristics and operational requirements of diverse scenarios, the Ruisu intelligent solar‑storage‑diesel system offers two architectural configurations—AC coupling and DC coupling—balancing technological maturity with operational efficiency to meet differentiated application needs.

1. AC-coupled system This design integrates photovoltaic inverters, power conversion systems (PCS), and diesel generators all connected to an AC busbar, featuring a mature technological framework and a wealth of engineering implementation cases. The architecture supports modular expansion, enabling flexible capacity upgrades in response to growing load demands, while also facilitating seamless participation in grid‑side ancillary services, thereby enhancing the overall value of the energy system.

2.  DC-coupled system The photovoltaic modules and the energy storage unit are directly connected to the DC bus via a DC/DC converter, and then converted into AC power by a centralized inverter to supply the load. This architecture reduces the number of AC–DC conversion stages, thereby significantly improving both the utilization efficiency of solar energy and the overall system efficiency. It is particularly well suited for applications involving high‑power, transient loads—such as fast‑charging stations—and helps ensure stable system operation.
