Case Study | SUNGO Energy Upgrades Mitsubishi Chemical with Photovoltaic Safety Shutdown

In the wave of global energy transformation, the chemical industry, as a significant consumer of energy and a major source of carbon emissions, is actively exploring green, safe, and efficient energy solutions. Recently, Mitsubishi Chemical, a leading global chemical company, has taken the lead in responding to this trend through collaboration with SUNGO Energy, successfully achieving a safe upgrade of its photovoltaic system and setting a benchmark for green transformation in the industry.

Project Background and Challenges

Due to the nature of its production, chemical parks have high demands for the stability, safety, and emergency response capabilities of energy supply. On one hand, production equipment requires continuous power supply to maintain process flow, and any power outage could lead to significant losses; on the other hand, there are flammable and explosive risks within the park, where traditional photovoltaic systems may cause secondary disasters due to DC arcs during faults or fires.

The core challenges faced by Mitsubishi Chemical's Chinese subsidiary include:

- Rapid Emergency Response: The need for quick shutdown of the photovoltaic system in extreme situations (such as fires or equipment failures) to prevent arc propagation.

- High Safety Standards: Compliance with the stringent electrical safety regulations of the chemical industry to avoid threats from high DC voltage to personnel and equipment.

- Efficient Operation and Maintenance: With a large-scale photovoltaic system, there is a need to reduce maintenance costs and enhance system reliability.

SUNGO Energy's Solution

In response to Mitsubishi Chemical's specific needs, SUNGO Energy meticulously customized an efficient and safe photovoltaic system solution. In this project, a total of 1,182 rapid shutdown devices, independently developed by SUNGO, were installed (utilizing a "one-to-two" design). These devices can quickly disconnect the DC high voltage between photovoltaic modules in emergency situations, effectively avoiding safety incidents such as arc fires, and providing a reliable barrier for the production safety of Mitsubishi Chemical.

Additionally, SUNGO Energy's solution incorporates a module-level intelligent monitoring system that can monitor the operating status of each photovoltaic module in real-time, significantly improving operation and maintenance efficiency, and ensuring the long-term stable and safe operation of the photovoltaic system.

Throughout the installation process, the SUNGO team provided comprehensive professional technical support to ensure that every detail met Mitsubishi Chemical's high standards. The team conducted in-depth demand alignment, provided on-site guidance, and performed meticulous inspections and adjustments post-installation, striving for perfection in every aspect, which earned high recognition and praise from Mitsubishi Chemical.

Industry Insights: From Chemicals to Other High-Safety Demand Fields

The successful implementation of the Mitsubishi Chemical project not only sets a model for the safe application of photovoltaics in the chemical industry but also demonstrates the broad application prospects of rapid shutdown technology in other industries with high safety requirements. Whether in hospitals, schools, hotels, or critical infrastructure such as pharmaceuticals and data centers, SUNGO's rapid shutdown devices can provide customized safety solutions, ensuring that while enjoying clean energy, comprehensive safety guarantees are also in place.

As global attention to photovoltaic safety policies increases, rapid shutdown technology is gradually becoming a standard configuration in new and retrofitted photovoltaic projects, especially in industries with high safety demands, where its acceptance and prevalence are continuously rising. As an expert in the MLPE (Module-Level Power Electronics) field and a mature provider of integrated intelligent energy solutions, SUNGO Energy is actively promoting the global dissemination and application of this technology, offering safe, efficient, and reliable intelligent energy solutions to more industry clients.
