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 Technical Specifications System Overview Nominal system voltage: 48V Maximum AC output power: 8000W Cabinet protection rating: IP54 Dimensions (W x D x H): 750 x 650 x 1130 mm Weight: Approx. 140 kg (battery-ready configuration) Total system weight and usable storage capacity depend on the number of batteries selected.

Yes. The Raython-R8 is supplied battery-ready as standard. Select the “0 Batteries” option if you plan to add batteries later. Can I add batteries after installation? Yes. The system supports up to four internal lithium batteries and can be expanded after installation. Does the system require a generator? No. Many systems operate purely on solar and batteries. A generator can be added for backup or seasonal support if required. Is this suitable for full off-grid living? Yes. With appropriate solar array and battery sizing, the Raython-R8 is suitable for full off-grid residential use.
