The Raython-R8 is an advanced 8kW all-in-one solar power system designed to provide reliable and sustainable energy for off-grid homes, holiday houses, and remote applications. By combining the 8kW 48V RIIOSUN hybrid inverter, four ES100II lithium batteries, and the TBB-E4 monitor into a single compact unit, the Raython-R8 delivers a powerful and user-friendly energy solution. This system is ideal for locations without grid access, where generators are commonly used, offering a cleaner, quieter, and more efficient alternative to traditional power sources.

Key Features:

All-In-One design for simple installation

The Raython-R8 is designed for fast and hassle-free installation, taking less than three hours to set up. As a fully assembled and factory-tested system, it eliminates the complexity of wiring and integration, allowing for a smooth installation process with minimal groundwork. Its IP54-rated enclosure provides robust protection, making it suitable for both indoor and outdoor environments.

Sustainable and efficient energy solution

With its eco-friendly design, the Raython-R8 reduces pollution, noise, and fuel consumption compared to conventional generator-based power systems. By integrating solar energy generation, battery storage, and intelligent energy management, it enables users to reduce their dependence on fossil fuels and lower their carbon footprint while maintaining a reliable power supply.

Seamless generator integration with AGS function

The system is equipped with an Automatic Generator Start (AGS) function, which intelligently controls the generator based on battery level, load demand, or predefined time settings. This ensures continuous power availability, even in cases of insufficient solar power or high energy demand, without unnecessary fuel consumption or manual intervention.

Advanced load management and Power Assist

The Raython-R8 is designed to handle heavy electrical loads, including air conditioners, refrigerators, water pumps, and washing machines. Its high surge capacity ensures stable performance when powering inductive loads with high startup currents. The Power Assist function allows the system to work in conjunction with a small generator, preventing overload and ensuring smooth operation without the need for oversized generators.

Reliable and intelligent energy distribution

The integrated energy management system optimizes power distribution between solar input, battery storage, and AC loads, ensuring efficient energy utilization. Leakage protection on the AC output enhances system safety, while the built-in smart load management feature prioritizes energy supply based on real-time demand.

Remote monitoring and smart control

The Raython-R8 supports real-time monitoring and remote management via the NOVA Web and mobile app. Through the TBB-E4 monitor, users can track system performance, view historical data, and adjust power consumption settings for improved efficiency. This intelligent monitoring capability allows users to make data-driven decisions to optimize energy usage and maximize solar self-consumption.

For users seeking a high-performance, easy-to-install, and sustainable energy solution, the Raython-R8 All-In-One Solar Power System offers unmatched reliability, intelligent automation, and seamless integration, making it the perfect choice for off-grid living and remote power applications.
