All in One Energy Storage System in Testing and Shipment

 

We Are Honored to Receive a Major Order for Residential Energy Storage Systems

We are pleased to announce that we have secured a significantly larger order of Residential Energy Storage Systems (RESS) from one of our valued customers. This milestone is not only a strong vote of confidence in our products and services, but also a testament to the growing global demand for reliable, clean, and intelligent home energy solutions.

Meeting Rising Demand with Reliable Capacity

As electricity prices continue to fluctuate and extreme weather events place increasing pressure on power grids worldwide, more and more households are looking for ways to take control of their energy future. Residential energy storage systems allow homeowners to store excess solar power during the day and use it at night or during outages — reducing electricity bills, increasing energy independence, and supporting a lower-carbon lifestyle.

This growing demand is exactly why our customer has expanded their order with us. To meet this increased volume, we have optimized our production planning, strengthened supply chain management, and expanded quality control capacity to ensure every system is delivered on time and to the highest standard.

Famous-Brand Components for Guaranteed Quality

Quality has always been the foundation of our business, and it is the core reason our customers keep coming back. For this order, we will continue to build our systems around world-renowned components:

Battery: We will use lithium iron phosphate (LFP) battery modules from internationally recognized brands such as BYD, Pylontech, and Dyness. These batteries are known for their exceptional safety, long cycle life (typically 6,000+ cycles), and stable performance across a wide temperature range — giving homeowners peace of mind for more than a decade of daily use.

Inverter: The systems will be equipped with hybrid inverters from leading brands such as Deye, Growatt, and SMA. These inverters deliver high conversion efficiency (up to 97%+), seamless switching between grid, solar, and battery power, and smart monitoring through user-friendly mobile apps.

By combining first-tier batteries and inverters with our mature system integration and rigorous factory testing, we ensure that every residential energy storage system we ship offers superior safety, efficiency, and reliability.

Why Customers Trust Us

Beyond component quality, our strength lies in complete system solutions. Each order is backed by:

• Professional system design tailored to local grid codes and customer requirements

• 100% pre-delivery testing, including full charge/discharge and communication protocol verification

• Certified compliance with international standards such as CE, IEC 62619, UN38.3, and VDE

Now most of factory plant rarely uses heating sealing provision on OPzV Battery Cases, only some factory to use it for Eliminateing weak points bu fusing the container and lid together and maintaining cleaning and professional finish battery container that reflects the premium quality of your brand.

Heat Sealed Feathures: heat sealing method creates a molecular bond, offering 100% leak- proof assurance and superior structural integrity that glue simple cannot match.

Packing Enhancement for OPzS Battery Container To Meet Save Cost Goal

 One of our valuable customers share feedback regarding the handling and transportation of our OPzS Babttery Containers. We understand their request to insert the OPzS 200AH (Small Volume) unit inside an OPzS 1000AH battery tanks as a way to optimize costs.

At the same time, we take seriously your concern about possible friction between the two containers, which could affect the smooth surface clairity, scratch the surface and overall presentation of the battery cases.

To address this, we have introduced an improved packaging method:each OPzS 200 battery box will be securely wrapped in high-density protective foam before placement into the OPzS 1000ah battery jar. This foam layer serves as a cushioning barrier, elimination direct contact and greatly reducing the risk of abrasion during handling, storage and transit.

We have carried out internal assessments to confirm that this configuration maintains both product integrity and visual quanlity. the solution aligns with your cost-efficiency goals while upholding our commitment to delivering products in excellent condition.

We are confident that every shipment will meet our rigorous quality standards and arrive ready for immediate use. we value your partnership and remain dedicated to providing solutions that balance performance, protection and cost effectiveness.
