TBB Power Raython-R8 8kW | All-In-One Off-Grid Solar Power System (Battery-Ready)

TBB Power Raython-R8 8kW All-In-One Off-Grid Solar Power System (Battery-Ready)

Reliable Off-Grid Power System – Designed as a Complete System

Clean, quiet and efficient off-grid energy with the TBB Power Raython-R8 all-in-one solar power system. Designed specifically for locations without grid access, the Raython-R8 replaces or significantly reduces reliance on generators by intelligently combining solar generation, battery storage and generator integration into a single factory-built enclosure.

The system is supplied battery-ready as standard (no batteries included) and can be configured with optional lithium batteries to suit your energy requirements at the time of purchase, with the flexibility to expand later as usage increases.

What Is Included (All Configurations)

• 8kW TBB Power RIIOSUN-II 48V Hybrid Inverter (transformer-based)
• Integrated Energy Management System (EMS)
• TBB E4 LCD Monitor
• IP54-rated steel enclosure
• Pre-wired AC & DC cabling
• AC & DC isolators and circuit protection
• Cooling system and internal battery racking

Important: Lithium batteries are selected via the product dropdown and are not included in the base battery-ready option.

Battery Configuration Options (Selectable)

The Raython-R8 supports flexible internal battery configurations using compatible TBB Power ES100II lithium battery modules.

• Battery-Ready (0 Batteries) – lowest upfront cost, ideal if batteries will be added later
• 2 x Batteries – approx. 10.08kWh usable storage
• 3 x Batteries – approx. 15.12kWh usable storage
• 4 x Batteries – approx. 20.16kWh usable storage (maximum internal capacity)

All batteries are installed internally and automatically managed by the system’s EMS.

Key Features

• 8kW continuous output – suitable for full off-grid homes and demanding loads
• Factory-built all-in-one system – significantly reduced installation time
• Battery-ready as standard – scale storage when required
• Automatic Generator Start (AGS) support
• Power Assist – combines battery and generator power for high surge loads
• 4ms transfer time – near-UPS performance for sensitive equipment
• Dual MPPT solar charge controllers
• Smart load prioritisation
• Remote monitoring via NOVA Web & mobile app

Generator Integration & Fuel Savings

The Raython-R8 is designed to integrate seamlessly with generators where required. Using Automatic Generator Start (AGS) and intelligent EMS logic, the system allows generators to:

• Run only when required
• Operate at higher, more efficient load levels
• Remain off during quiet periods using battery power instead

This significantly reduces fuel consumption, noise and maintenance compared to generator-only systems, while extending generator service life.

Typical Applications

• Off-grid homes and cabins
• Holiday homes and lodges
• Remote workshops and offices
• Generator replacement or hybrid systems
• Sites requiring quiet-hour or low-noise operation
