TBB Power 8kW Raython-R8 All-In-One Solar Power System (Batteries not included)

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 , the TBB-E4 monitor , and up-to-four ES100II lithium batteries (sold separately) 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 factory pre-assembled and fully tested, reducing installation time to under three hours. It features a rugged IP54-rated enclosure , ensuring protection against dust and water ingress—perfect for indoor or outdoor deployment .

Sustainable and Efficient Energy Solution

The system integrates solar generation , battery storage , and intelligent energy management to minimise fossil fuel usage. Compared to conventional generator-only systems, it significantly reduces noise, emissions, and fuel consumption—helping you operate sustainably and cost-effectively.

Seamless Generator Integration with AGS Function

The built-in Automatic Generator Start (AGS) feature intelligently manages generator usage based on load, battery state-of-charge, or time schedules. When paired with larger generators , the Raython-R8 enables them to run for shorter, high-output periods , greatly improving fuel efficiency by reducing idle or low-load runtime.

Hybrid Generator Kit Compatibility

Designed to work seamlessly in hybrid generator setups , the Raython-R8 allows smart energy blending between renewable and generator sources—offering reliable backup without sacrificing efficiency.

Advanced Load Management & Power Assist

Its high surge capacity makes it ideal for heavy inductive loads like air conditioners, pumps, and power tools. With Power Assist , the system can temporarily combine battery and generator power, preventing overload and allowing use of smaller or existing generators without system compromise.

Fast Transfer Time

With a transfer time of just 4ms , the Raython-R8 ensures near-instant switchover between power sources, providing uninterrupted operation for sensitive appliances and critical systems.

Reliable and Intelligent Energy Distribution

The built-in smart EMS (Energy Management System) dynamically balances solar, battery, and generator power. AC output includes leakage protection for enhanced safety, while smart load prioritisation ensures critical loads are always powered.

Remote Monitoring and Smart Control

With integrated support for the TBB E4 display and the NOVA Web and mobile app , users can remotely monitor performance, view historical data, and fine-tune settings to optimise performance and boost solar self-consumption.

Included in the Raython-R8:

• 8kW 48V TBB Power RIIOSUN-II Hybrid Inverter Charger (Transformer-based design)

• TBB Power E4 LCD Monitor

• IP54-rated portable cabinet with: Pre-wired cables AC/DC switches AC/DC circuit breakers Cooling fans Racking space for up to 4 x ES100II batteries

For users seeking a powerful, fuel-efficient , and intelligently integrated solar power system , the Raython-R8 delivers exceptional performance with minimal setup and maximum control—ideal for off-grid living, hybrid systems, and backup power in remote locations .
