TR8500WX-PRO Residential Energy Storage System Earns ETL Listing to UL1973, UL9540 and UL9540A

LITHTECH’s wall-mounted residential energy storage system has completed full-chain safety certification by Intertek (ETL), together with UN38.3, an SDS and a maritime transport assessment report.

Recently, LITHTECH’s wall-mounted residential energy storage system, the TR8500WX-PRO, has passed comprehensive, rigorous testing and evaluation based on the UL1973, UL9540 and UL9540A standards, and has simultaneously obtained UN38.3, an SDS and a maritime transport assessment report.

This testing and certification was completed by the internationally recognized body Intertek (ETL), which issued the ETL Listing, covering the complete safety chain from cell, module and system to the finished unit and fire propagation. It marks a new milestone in LITHTECH’s product safety, system integration and global compliance capabilities.

Market Value: Unlocking Access, Strengthening Global Competitiveness

ETL certification to UL standards clears the way into the North American market for this product; in Europe and other overseas markets, the testing endorsement against UL — a top-tier international safety standard — is equally a strong asset for earning the trust of customers and channel partners.

Together with UN38.3, the SDS and the maritime report, the product meets complete air, land and sea export-compliance requirements, materially reducing partners’ risk in compliance and project deployment.

Safety Value: End-to-End Validation, Safety as a Non-Negotiable Baseline

Thermal-runaway propagation testing based on the UL9540A standard requires coordinated performance across intrinsic cell safety, multi-level BMS protection, thermal management and system integration — any single weak point means failure.

The inherently more stable LiFePO4 chemistry, combined with multiple layers of protective design, turns “safe and reliable” from a marketing line into a hard metric verified by independent third-party testing.

Performance Value: Stable and Reliable, Adaptable to More Scenarios

The 51.2V 314Ah LiFePO4 cells provide a solid foundation in cycle life and operational stability; the wall-mounted design simplifies residential installation; and compatibility with most mainstream inverters gives customers greater freedom in system selection — one battery, more possible configurations.

Management Value: Manufacturing Consistency, Traceable Quality Control

Issued by the international testing and certification body Intertek under its ETL Listing, this certification covers not only product testing but also factory audits and ongoing surveillance.

Through standardized production and quality-control processes, LITHTECH ensures that mass-produced units stay consistent with the certified samples, turning a one-time pass into a sustainable manufacturing capability.

Brand Value: Authoritative Endorsement, Reinforced Overall Strength

Passing, in a single round, the full set of ETL certification based on the UL1973, UL9540 and UL9540A standards is a systematic test of LITHTECH’s R&D, validation and quality systems, and a concentrated demonstration of the company’s overall strength.

This authoritative third-party endorsement further solidifies LITHTECH’s brand image in international markets and strengthens the confidence of customers, channels and partners.

This certification is not only an affirmation of a single product, but solid proof of LITHTECH’s product philosophy — safe, reliable and easy to deploy. From residential and commercial & industrial to marine energy storage, LITHTECH will continue to benchmark against international standards, advancing steadily toward its goal of becoming a full-scenario energy storage system solution integrator.
