Shenzhen PowerSTN Energy Co., Ltd. is a premier China-based manufacturer specializing in advanced off-grid energy storage systems (ESS). Our focus on the New York market stems from the region's aggressive transition toward renewable energy, mandated by the Climate Leadership and Community Protection Act (CLCPA).
We provide a comprehensive portfolio of Tier-1 lithium-ion solutions, ranging from 5kWh residential stackable units to 2MWh industrial containerized systems. By operating modern manufacturing facilities in Shenzhen, we combine the efficiency of the world’s leading battery supply chain with the specific engineering requirements needed for North American compliance.
Our engineering teams focus on Information Gain—delivering technical insights that help New York installers navigate the complexities of UL 9540A testing and FDNY fire safety requirements.
New York is currently at the forefront of the global energy revolution. As the grid faces mounting pressure from aging infrastructure and extreme weather events like Nor'easters, the demand for resilient off-grid and hybrid systems has surged.
For industrial facilities in Long Island and Upstate New York, a power outage isn't just an inconvenience; it's a massive financial loss. Our BESS solutions provide seamless UPS-grade switching, ensuring that critical operations continue even when the ConEd or PSEG grid fails.
NYC's push for electric vehicle adoption requires local energy storage to mitigate "Demand Charges." Our systems act as buffers, storing energy during off-peak hours and discharging during high EV charging demand, significantly reducing operational costs for fleet owners.
Upstate New York farms are increasingly adopting off-grid solar + storage to power remote irrigation systems and dairy facilities where extending the traditional grid is cost-prohibitive.
As a leading factory, PowerSTN is not just manufacturing for today but engineering for 2030. Our technical roadmap includes:
The synergy between our Shenzhen factory and our New York distribution partners creates a resilient supply chain. While many competitors suffer from component shortages, PowerSTN maintains strategic reserves of Tier-1 cells (CATL, EVE, BYD), ensuring that NY projects remain on schedule.
Scale of production and direct access to raw materials allow us to provide a 30% cost advantage over domestically assembled units without compromising on quality.
We specialize in UL 9540 and UL 1973 certifications, which are mandatory for insurance and legal operation within New York State jurisdiction.
The company operates modern manufacturing facilities equipped with advanced production technologies and strict quality control procedures. From battery cell selection and battery pack assembly to system integration and performance testing, every stage of production is managed to ensure reliability, safety, and long-term operational performance.
PowerSTN serves customers across multiple industries, including renewable energy, telecommunications, data centers, utilities, manufacturing, commercial facilities, and infrastructure projects. Its engineering team works closely with clients to deliver customized energy storage solutions tailored to specific project requirements and operational environments.
In addition to manufacturing capabilities, Shenzhen PowerSTN Energy Co., Ltd. offers OEM and ODM services for global brands, distributors, system integrators, and energy solution providers. By combining technical expertise, flexible production capacity, and customer-focused support, the company aims to be a trusted partner for organizations seeking reliable and scalable energy storage technologies in the rapidly evolving global energy market.

A: Our systems are designed to meet UL 9540 (for the complete system) and UL 1973 (for the battery modules). These are the primary standards recognized by NY State and NYC authorities for safety and insurance compliance.
A: We work with specialized hazardous materials logistics partners to provide DDP (Delivered Duty Paid) or CIF options to the Port of New York and New Jersey, ensuring all customs and battery disposal fees are managed.
A: Yes, our hybrid inverters are AC-coupled compatible, meaning they can be integrated into existing solar installations without replacing your current solar inverters, making them ideal for NY retrofits.
A: Typically, production takes 8-10 weeks, followed by 4 weeks for ocean freight. We provide real-time tracking and factory acceptance testing (FAT) via video link for our NY clients.
