Risen Energy Launches Lifetime Warranty for PCS, Elevating After-Sales Assurance for All-Liquid-Cooled SiC C&I Storage System

April 2026 — Risen Energy Co., Ltd. has officially introduced a lifetime warranty service synchronized with the battery cell lifecycle for the Power Conversion System (PCS) — the core component of its all-liquid-cooled silicon carbide (SiC) 131kW/261kWh commercial and industrial (C&I) energy storage system. Backed by advanced technology and centered on long-term customer value, this move sets a new benchmark for after-sales assurance in the energy storage industry.

Redefining Warranty Standards: Aligned with Battery Lifecycle

As the central power electronics unit in an energy storage system, PCS typically comes with an industry-standard warranty of 3–5 years. However, concerns over component replacement and long-term operation and maintenance (O&M) costs have remained a key pain point for customers.

Leveraging the advantages of SiC technology, Risen Energy is redefining after-sales standards by aligning the PCS warranty period with the battery cell lifecycle. Specifically, the PCS warranty for its all-liquid-cooled SiC 131kW/261kWh C&I energy storage system is synchronized with the battery’s design lifespan — based on calendar life (typically 10–15 years), more than 6,000 deep charge-discharge cycles under standard conditions, and industry-recognized benchmarks (capacity retention ≥80% of nominal capacity). Within this effective lifecycle of the battery cells, Risen Energy ensures the stable and reliable operation of PCS hardware throughout.

This initiative significantly alleviates customers’ long-term O&M burden, avoids mid-term replacement costs of critical components, and safeguards the stable operation and long-term returns of energy storage projects.

Robust SiC Technology Underpins Warranty Commitment

Risen Energy recognizes that customers prioritize not only warranty duration, but also stable performance throughout the entire lifecycle of their energy assets. Built on robust hardware capabilities and a stringent quality control system, the company is committed to delivering long-term, reliable protection.

Unlike conventional silicon-based devices combined with air cooling or standard liquid cooling solutions, Risen Energy’s all-liquid-cooled SiC PCS integrates advanced SiC chips with a full liquid cooling architecture. This significantly enhances resistance to aging and load stress at the hardware level, greatly improving long-term operational stability and reliability — forming a solid technological foundation for its warranty commitment.

Hassle-Free Relocation with Continuous Service Support

To ensure proper implementation of warranty benefits, Risen Energy has introduced a streamlined process for system relocation. Customers can retain full warranty coverage by completing a simple registration in advance.

Risen Energy’s professional service team will conduct a comprehensive assessment of the new site, including grid conditions, temperature and humidity environment, and installation requirements, ensuring compliance with operational standards. Project service records will be updated simultaneously to enable seamless continuation of lifecycle-synchronized warranty coverage.

Through standardized and professional after-sales services, customers can truly benefit from a “one-time investment, full-lifecycle protection” model — optimizing lifecycle costs and enhancing overall investment returns.

Driving Long-Term Value in Global Energy Transition

As a leading global provider of integrated renewable energy solutions, Risen Energy remains committed to addressing customer needs through high-quality products and technological innovation. The company delivers efficient and reliable solar-plus-storage solutions across residential, commercial and industrial, and utility-scale applications.

Looking ahead, Risen Energy will continue to uphold stringent quality standards and enhance its service systems, creating long-term value for customers while advancing the industry toward higher quality and greater sustainability.
