GSL Energy Warranty: Comprehensive After-Sales Support, Safeguarding Every Customer's Energy Peace of Mind

1.GSL Energy Warranty: Comprehensive After-Sales Support, Safeguarding Every Customer's Energy Peace of Mind

At GSL Energy, delivering high-quality energy storage batteries is merely the starting point for building long-term trust with our customers. We understand that as a core component of energy supply, the stable operation of energy storage systems directly impacts our customers' production efficiency, daily life, and business development. Therefore, professional, efficient, and attentive after-sales support is equally important as the premium products themselves. We are committed to eliminating customer concerns through transparent service processes, immediate technical support, and practical solutions. This ensures not only reliable energy storage products but also worry-free after-sales assurance throughout the entire lifecycle. From initial installation guidance and mid-term troubleshooting to long-term technical training, GSL Energy's warranty service spans the entire product usage cycle, striving to maximize value for our customers.

2. Installation & Technical Support: From "Paper Guidance" to "Real-Time Assistance" for Zero-Error Installation

The quality of energy storage battery installation directly determines subsequent safety and stability. To ensure seamless installation for customers, GSL Energy equips every energy storage battery product with a comprehensive and easy-to-understand user manual. This manual not only provides clear step-by-step installation procedures (such as equipment mounting, wiring connections, and interface matching) but also includes high-definition diagrams and important notes (such as waterproofing and moisture protection requirements, wiring standards, and safety distance specifications). Even technicians new to the product can quickly grasp the installation essentials through the manual.

However, we recognize that printed manuals alone cannot address every complex scenario. When customers encounter unique challenges during installation—such as non-standard site conditions, interface compatibility questions, or unexpected technical issues—GSL Energy's engineering team provides "real-time video conference support": Customers simply initiate a video request via phone or computer. Our engineers connect within minutes, visually assessing the site through the video feed to provide one-on-one real-time guidance. From the torque required for a single screw to the wiring layout of an entire system, engineers offer precise recommendations based on professional expertise, ensuring every installation step meets standards. Additionally, for large-scale energy storage projects or complex installation scenarios, we offer preliminary on-site surveys. Engineers will visit the location beforehand to assess the environment and develop customized installation plans, mitigating risks at the source for a more efficient and secure installation process. 2. Product Issue Resolution: “Step-by-Step Troubleshooting + Rapid Response” to Minimize Downtime Losses

Energy storage batteries may encounter faults during long-term use. GSL Energy understands that downtime not only disrupts normal power usage but can also cause economic losses. Therefore, we have established a fault resolution mechanism centered on "rapid troubleshooting, precise identification, and swift resolution." Through a scientific step-by-step troubleshooting approach, we resolve issues in the shortest possible time, minimizing downtime costs for our customers.

Typically, there are two main causes for energy storage battery failure. We provide targeted solutions for each:

(1) BMS (Battery Management System) Malfunction: "Remote Diagnosis + Free Expedited Shipping" for rapid repair.

As the “brain” of energy storage batteries, the BMS monitors battery status and manages charging/discharging processes, serving as the core component ensuring safe operation. In actual failure cases, approximately 80% of issues stem from minor BMS faults (e.g., software glitches, sensor anomalies, communication interruptions). For such issues, GSL Energy engineers first conduct remote diagnostics to swiftly pinpoint the cause: Customers need only photograph the indicator light status and error codes of the faulty device, or describe abnormal behavior via video (e.g., failure to start, abnormal charging/discharging, blank screen). By cross-referencing product specifications with our fault database, engineers can preliminarily determine if the BMS is at fault within 30 minutes.

Once BMS failure is confirmed, we immediately activate our "Free Replacement + Express Logistics" service: Dedicated personnel coordinate new BMS components, prioritizing international couriers like DHL (domestic customers receive next-day delivery via SF Express) to ensure swift delivery. Engineers simultaneously provide video-guided replacement instructions to facilitate rapid customer installation.

(2) Cell or Module Issues: "Free Replacement + Full Assistance" to Ensure System Stability

Although GSL Energy subjects batteries to multiple stringent tests during production (including high/low-temperature cycling, charge/discharge lifespan, and safety performance tests) to minimize cell/module failure rates, we offer worry-free solutions should issues arise (e.g., excessive cell capacity degradation or module connection faults).

Upon confirmation by our engineers through remote diagnostics or on-site inspection that the fault originates from a battery cell or module, GSL Energy will provide customers with new replacement cells or modules free of charge based on the specific failure condition, covering all associated logistics costs. For the replacement process, we offer two support options: If the customer's technical team possesses the capability to perform the replacement, our engineers will provide detailed replacement procedure manuals and video guidance to ensure standardized operations. If the customer requires assistance, we can also arrange for engineers to visit the site to personally complete module replacement and system commissioning. After replacement, the engineer will conduct comprehensive testing of the entire system, ensuring stable operation is restored before departure, eliminating any concerns about post-replacement performance for the customer.

3. Training and On-Site Support: Empowering Customers to "Fish for Themselves" and Enhance Self-Maintenance Capabilities

GSL Energy believes that quality after-sales support should not only “solve immediate problems” but also "help customers prevent future issues." Therefore, we integrate "technical training" as a vital component of our warranty services. Through systematic training, we enhance the operational and maintenance capabilities of our clients' technical teams, enabling them to transition from "reliance on external support" to "autonomous system management."

(1) Factory Professional Training: Deepen product understanding and master core maintenance skills

We strongly recommend clients dispatch technical engineers to GSL Energy's factory for complimentary professional training. Led by senior engineers with over 10 years of energy storage industry experience, the curriculum covers: - Core product principles (e.g., battery structure, BMS operation, energy storage system logic) - Daily maintenance essentials (e.g., routine inspection items, cleaning methods, anomaly identification) - Practical troubleshooting techniques (e.g., assessing battery health via data, rapid fault localization and resolution)

The training adopts a blended "theory + hands-on practice" approach: During theoretical sessions, engineers illustrate concepts using real-world case studies to aid comprehension. In practical sessions, trainees operate various energy storage equipment in the factory's training workshop, simulating installation, commissioning, and troubleshooting scenarios to translate theoretical knowledge into practical skills. Upon successful completion, participants receive a training certificate. We also establish a "Trainee Communication Group" where graduates can consult our engineers anytime for ongoing support.

(2) On-site Training and Support: Customized on-site training to address unique requirements

For clients unable to send personnel to our facility or with specialized training needs (e.g., project-specific operational training or simplified training for frontline O&M staff), GSL Energy can dispatch engineers to conduct training at the client's location. Engineers will tailor training programs based on actual client needs and technical team proficiency levels. For example: - For operations teams at large-scale energy storage plants, training emphasizes comprehensive system monitoring, data analysis, and emergency response protocols. - For technicians at small-to-medium commercial/industrial sites, training focuses on routine inspections, basic troubleshooting, and safety operating procedures.

Additionally, during project commissioning or when clients encounter significant technical challenges, our engineers can promptly deploy on-site support. Whether assisting clients in establishing comprehensive equipment maintenance protocols or resolving complex system failures, our engineers operate with a dual objective: solving immediate issues and imparting skills. Beyond addressing current needs, they explain underlying principles and countermeasures to the client's technical team, progressively enhancing their autonomous maintenance capabilities to ensure long-term stable operation.
