onesuntech.com is the official website of OneSun Technology (Yiyang New Energy Technology Co., Ltd.), a Shenzhen, China-based integrated photovoltaic energy storage product manufacturer founded in 2014. The company owns its own production facility in Huizhou, Guangdong, with core business focused on the manufacturing of energy storage lithium batteries and photovoltaic inverters. It offers a full range of photovoltaic energy storage solutions for global customers, ranging from portable solar generators to large container-style energy storage systems for commercial and industrial use. It supports OEM/ODM customization and SKD/CKD semi-knocked-down/complete knocked-down component supply, and its products have been exported to more than 70 countries worldwide.
The company's core advantage lies in its independent layout of the entire industrial chain: it operates both battery and inverter factories, independently develops automotive-grade BMS battery management systems, and delivers outstanding core technical indicators: MPPT tracking efficiency reaches 99.99%, maximum conversion efficiency exceeds 98%, and some of its technologies are industry-exclusive innovations. Its full product range covers portable solar power generation, all-in-one residential energy storage, commercial and industrial cabinet/container energy storage systems, lithium battery cells, and photovoltaic inverters, to meet demands for different power outputs and capacities.
The official website does not publish unified retail pricing. All products use a custom quotation model based on customer requirements: customers communicate their needs to get a customized solution and quotation, and arrange production after paying a deposit or full amount upon signing the contract.
For advantages, the manufacturer has over 10 years of industry experience. End-to-end in-house production brings clear advantages in cost and quality control. All products hold complete certifications, come with long warranty periods, and the battery can offer a warranty of up to 20 years. They also meet compliance requirements for different global markets. The downsides are that the website is mainly targeted at B2B clients, with no public detailed specifications or pricing, so ordinary retail users face a high barrier to accessing information. The website also has a user experience issue of duplicated content.
This website is suitable for global photovoltaic energy storage distributors, system integrators, and commercial and industrial energy storage project owners looking for OEM/ODM manufacturing or bulk purchases of energy storage products. Individual retail users cannot purchase finished products directly through this website.
As the official website of a Chinese company, it can be accessed directly and normally from within mainland China, no VPN proxy is required.
