1. All-in-One ESS: Simplified Deployment and Enhanced Reliability

Traditional energy storage systems usually consist of multiple separate components such as batteries, inverters, and controllers, resulting in complex wiring and long on-site commissioning times. ONESUN’s All-in-One ESS solutions integrate lithium batteries, power inverters, and intelligent control systems into a single compact unit, eliminating complicated configuration requirements.

This integrated design enables faster installation, improved safety, and higher system reliability. It is widely used in residential, commercial, and light industrial scenarios, allowing users in off-grid or unstable-grid regions to access stable and reliable electricity with ease.

All in one ESS

ONESUN’s All-in-One Energy Storage Systems cover power ranges from several kilowatts up to more than ten kilowatts, meeting diverse energy demands. All systems adopt high-safety LiFePO₄ battery technology combined with intelligent Battery Management Systems (BMS), ensuring safe operation under harsh conditions such as high temperatures and vibration. With a cycle life exceeding 6,000 cycles, these systems are built for long-term, global deployment.

2. PAYGO Model: Lowering Entry Barriers and Enabling Energy Access

High upfront costs have long been a major obstacle to ESS adoption. To address this challenge, ONESUN has introduced the innovative PAYGO (Pay-As-You-Go) model, also known as the “pay-per-use” solution.

Instead of paying the full cost upfront, end users make a small initial payment and then pay weekly, monthly, or quarterly installments to activate the system. With built-in smart remote control technology, system usage is linked to payment status. If payments are overdue, the system can be temporarily disabled and automatically reactivated once payment is completed.

The core value of PAYGO lies in dramatically reducing the initial purchasing threshold, significantly improving market penetration. In regions such as Africa, Southeast Asia, and the Middle East—where power infrastructure is limited and distributed energy demand is strong—PAYGO enables easier access to clean energy. At the same time, it provides distributors and partners with healthier cash flow and effective risk control, creating a more sustainable energy storage ecosystem.

3. One-Stop ODM & OEM Services: Accelerating Brand Launch

With years of experience in the new energy industry, ONESUN offers not only standardized ESS products but also a mature ODM (Original Design Manufacturing) and OEM (Original Equipment Manufacturing) service system.

Whether partners aim to build their own branded energy storage products or develop customized features for specific markets, ONESUN provides a one-stop solution—from battery pack design and industrial appearance customization to system parameter configuration and PAYGO business model integration.

Lithium Battery OEM & ODM Factory

Unlike traditional contract manufacturing, ONESUN possesses full value-chain R&D and manufacturing capabilities, covering battery cells, BMS, and inverters. This ensures high cost-performance while maintaining industry-leading standards in performance, safety, and reliability. The integrated service model also significantly shortens the time from product design to market launch, enabling partners to gain a competitive edge quickly.

4. Global Vision with Localized Support

Founded in 2014, ONESUN has grown into a well-established global energy storage brand. Its products have been exported to more than 70 countries and regions, with over 3GW of projects successfully delivered worldwide and customer satisfaction reaching approximately 90%.
