Off-Grid Solar System Packages with Batteries + PAYGO | ONESUN OEM/ODM Solutions

In the global wave of energy transition and green development, “Off-grid solar system packages with batteries + PAYGO” (off-grid solar systems with batteries combined with Pay-As-You-Go models) is emerging as a major force in addressing electricity shortages in remote areas and improving energy access. In this field, the well-known battery brand manufacturer ONESUN (Shenzhen Wanyou Sunshine Technology) is providing optimal overall solutions to global customers through its strong product performance, flexible business models, and comprehensive ODM/OEM customization capabilities.

I. What is an Off-Grid Solar System Package?

An off-grid solar system package refers to an independent energy system that does not rely on the public power grid. It typically consists of the following key components:

- Solar panels (PV panels): convert sunlight into electrical energy;
- Battery energy storage system (high-safety LiFePO₄ cells, etc.): store electricity to ensure power supply at night or on cloudy days;
- Inverter: converts DC electricity from the battery into AC electricity usable by households or appliances;
- Accessories, mounting brackets, and cables: used for system installation and connection.

ONESUN’s off-grid system packages range from 1 kW to multi-kilowatt levels, with complete configurations that enable fast deployment and easy installation. They are suitable for homes, schools, clinics, farms, and even small commercial and industrial facilities in areas without reliable grid access.

II. PAYGO Model — Making Clean Energy More Accessible

PAYGO (Pay-As-You-Go), or “pay-as-you-go/rent-to-own” model, is an innovative purchase and usage solution launched by ONESUN. Its core advantages include:

Significantly lowers the upfront investment barrier
Traditional off-grid solar systems require a large one-time payment, which is a heavy burden for many households or small businesses. With PAYGO, users can start using the system first and pay later — only a low down payment or periodic installments (weekly, monthly, or quarterly) are needed to keep the system running.

Remote intelligent management and risk control

ONESUN’s PAYGO systems feature remote control and authorization activation mechanisms:

- After payment, the system generates a one-time activation code;
- The user enters the activation code to enable normal operation;
- If payment is not made on time, the system automatically enters standby mode to prevent misuse or default risk.

This design ensures continuity of electricity use for customers while providing partners with a reliable tool for stable cash flow management.

III. ONESUN’s Product Highlights in Off-Grid and PAYGO Applications

ONESUN’s off-grid solar systems and battery products feature the following strengths:

√ Fully integrated, one-stop system

ONESUN’s complete off-grid packages include solar panels, high-quality lithium battery storage units (LiFePO₄), inverters, and all necessary accessories — truly “plug-and-play” with no need for customers to source and match components themselves.

√ High-performance batteries with strong safety assurance

ONESUN places strict emphasis on battery quality and safety. Its products use A-grade LiFePO₄ cells, offering high safety, durability, and long cycle life, while complying with multiple international standards and adapting to various environmental conditions.

√ Wide range of models and flexible configurations

From small 1 kW off-grid systems to large-capacity 6 kW or even higher energy storage systems, ONESUN offers multiple specifications that can be flexibly configured according to actual user power consumption needs.

IV. ODM & OEM — Creating Optimal Solutions for Partners

In addition to standard products, ONESUN provides comprehensive ODM (Original Design Manufacturing) and OEM (Original Equipment Manufacturing) services to global clients, including:

Independent R&D and customization capabilities

ONESUN possesses complete in-house production lines for batteries, BMS (Battery Management Systems), inverters, and energy management systems. It can customize product appearance, system configuration, and functional integration according to the partner’s brand positioning.
