TBB Power Raython-R8 8kW All-in-One Solar Power System with 4 x ES100II Batteries

The TBB Power Raython-R8 is a fully integrated all-in-one solar energy storage system designed to provide complete off-grid power for remote homes, holiday properties, cabins, agricultural facilities, and hybrid generator applications. The system combines an 8kW 48V hybrid inverter charger, lithium iron phosphate battery storage, intelligent energy management, and monitoring within a single IP54-rated cabinet for simplified installation and reliable operation.

Engineered for standalone energy systems, the Raython-R8 enables independent power generation, storage, and distribution without reliance on utility grid infrastructure. Integrated Automatic Generator Start (AGS) functionality allows coordinated generator support when required, ensuring continuous power availability while improving fuel efficiency.

Dual MPPT solar inputs support flexible PV array design, while Power Assist enables temporary load support by combining inverter and generator power. Fast transfer switching supports uninterrupted operation of connected appliances and critical loads.

The integrated energy management system prioritises loads, balances available energy sources, and enables remote monitoring through the TBB E4 display and NOVA web/mobile platform.

The system is supplied as a complete cabinet-based solution suitable for indoor or sheltered outdoor installation.
