With the implementation of favorable electricity pricing policies and subsidies across Europe, an increasing number of businesses are exploring more intelligent and efficient solutions for Commercial & Industrial (C&I) energy storage. However, enterprises often face various challenges in the process of adopting these systems, including difficulties in product selection, high initial investment, lack of clear ROI metrics, complexity of installation, concerns about the safety of energy storage systems and lack of responsive customer service.

Founded with the mission to address these obstacles in the C&I energy storage sector, Dunext has already accumulated years of extensive experience in the PV and ESS industry. The company's core team, comprising experts from leading companies like Huawei, Sungrow, and BYD, is exceptionally seasoned and brings a combined expertise of over 15 years in power electronics, digital technologies, energy storage, and thermal management. The broad experience has significantly strengthened Dunext's R&D capabilities, empowering the company to develop and deliver innovative and high-performance solutions. Dunext offers a comprehensive product portfolio of PV and ESS, crafted to meet diverse energy needs across residential and C&I scenarios. In particular, the company has developed PowerHill, an all-in-one C&I BESS solution, through continuous innovation, establishing a technological edge in the C&I storage market. With a growing global presence, Dunext has already achieved substantial progress in European markets like Poland and Romania, earning strong positive feedback from industry leaders.

Simplifying Product Selection and Enabling Flexible Expansion

The market offers a wide range of energy storage solutions, making it challenging for business owners to determine the most suitable option for their needs. Evaluating factors such as system scalability, compatibility with existing energy infrastructure, and hidden costs beyond initial procurement and installation expenses can be overwhelming. Enterprises often overlook long-term costs, such as potential upgrades or expansions, which can significantly impact the total cost if not thoroughly assessed upfront.

As a dedicated expert in C&I energy storage, Dunext simplifies decision-making with PowerHill ESS. No need for additional inverters or complex systems, PowerHill can seamlessly connect with existing energy infrastructure with efficient DC coupling solution. It supports versatile energy sources, including photovoltaic, wind, and diesel generator, delivering tailored solutions to meet diverse business needs. Meantime, PowerHill also provides access to multi-grid ancillary services and ensures scalability for expansion, enabling businesses increase power capacity without costly grid upgrades. This makes it easier for corporates to achieve satisfying returns on investment while optimizing energy usage, offering them a flexible, future-proof solution to adapt to evolving energy demands. 

All-in-One Design for Easy Installation

Installation of energy storage systems is often complicated and costly, particularly in Europe, where labor and installation costs are significantly high. Typically, it requires specialized teams who not only need to be familiar with the storage equipment but also understand how to integrate it with other energy sources to ensure optimal performance.

Dunext solves these problems with its innovative plug-and-play, all-in-one energy storage solutions. PowerHill features a pre-fabricated design, ensuring the system arrives fully assembled, ready for quick connection and commissioning, enabling rapid deployment with ease. Installation of the system takes less than 2 hours, while the connection process usually takes around 30 minutes, minimizing the need for extra manpower and significantly reducing transportation and installation costs. With Dunext, enterprises benefit from a streamlined installation process that not only saves time and money but also ensures optimized energy management from day one.

Five-Layer Safety Design for Enhanced Security

Safety remains a critical concern when it comes to energy storage systems, especially during charging and discharging cycles. Risks such as overheating, short-circuiting, or battery failure could lead to severe safety incidents, like fires, which could disrupt energy supply and put corporates at operational risk.

To mitigate these risks, Dunext’s PowerHill adopts a Five-Layer safety design, incorporating over 60 efficient safety test strategies that span from individual components to the entire system. The design includes a fire detection system and an advanced fire suppression system, ensuring early risk detection and preventing accidents from escalating.

Cell Level: Utilizes LFP (Lithium Iron Phosphate) chemistry for intrinsic safety, effectively preventing overheating and thermal runaway.

Pack System: Incorporates two-bolt insulation installation and pack-level status monitoring to enhance operational reliability.

Monitoring System: Leverages advanced AI and big data technologies analytics to predict thermal risks, providing early warnings and proactive system protection.

Electrical System: Employs multi-tier protections to prevent fault propagation and escalation of system issues.

Cabinet level: Includes explosion relief and ventilation structures to mitigate fire and explosion risks.

This comprehensive safety framework minimizes operational risks while enhancing system stability, providing corporates assurance in reliable and secure energy storage.

Professional Localized Service Support

Another concern for business owners using energy storage solutions is the risk of poor or delayed customer service. When energy storage systems encounter malfunctions or operation faults, clients sometimes fail to receive timely response or adequate support. Without a robust service and maintenance network, even minor issues may escalate and result in decreased system performance or more severe failures. Delays in repair and maintenance can disrupt production or operations, leading to financial losses. Furthermore, European clients may face more challenges like language and cultural barriers in after-sales services. The absence of local service teams or language support can hinder timely and effective responses.

Understanding that quick and reliable service is essential to maintaining business operations, Dunext has built a dedicated and professional customer support team to offer end-to-end service from pre-sales consultation to post-sales technical support. Equipped with deep expertise in energy storage technologies, the Dunext team provides precise product advice and solutions tailored to client needs. Combining remote hotline supports with on-site technical assistance, Dunext establishes a rapid-response mechanism to help clients address issues promptly, minimizing downtime and operational impact. To better serve European clients, Dunext has set up service centers in UK, Poland and Romania and offers multi-language support, which ensures that clients receive timely assistance, regardless of their location. Additionally, the company provides clients with an intelligent O&M platform, Dulink, which facilitates fault diagnosis and analysis, enabling efficient troubleshooting and enhancing energy management efficiency. 

Since its establishment, Dunext has been committed to tackling key challenges in the C&I energy storage sector through innovation-driven solutions. Guided by a vision to accelerate energy transformation for businesses, Dunext leverages intelligent operations and advanced technology to ensure its products and services stay at the forefront of the industry, laying a solid foundation to become a future leader in this sector. Collaborating closely with its clients and partners, Dunext not only addresses current industry challenges but is also poised to drive a sustainable and green future for the global energy landscape.
