RIIO SUN II 8KVA/48V SOLAR INVERTER -(TBB)

Description

The TBB RiiO Sun II 8KVA/48V is a brand-new, versatile all-in-one transformer-based hybrid solar inverter engineered for backup power, off-grid, and energy storage system (ESS) applications. It combines a pure sine wave inverter, a 90A AC battery charger, dual MPPT solar charge controllers, and a rapid 4ms automatic transfer switch into a single compact unit — with an improved display interface and a better human-machine interface compared to the original RiiO Sun series. The transformer-based design gives it exceptional durability, high surge handling capability, and the robustness needed to power heavy loads and motor-driven appliances reliably. With support for parallel and three-phase operation across up to 9 units, it scales from a single home backup solution all the way up to a 72KVA commercial or industrial power system making it one of the most scalable and versatile all-in-one hybrid inverters in its class.

Key Features

• All-in-One Design: Integrates a pure sine wave inverter, dual MPPT solar charge controllers, a 90A AC battery charger, and a 4ms automatic transfer switch in a single compact unit, simplifying installation and reducing wiring complexity.
• Transformer-Based Construction: The heavy-duty transformer core provides exceptional surge handling at 300% rated power 
• Dual MPPT Solar Charge Controllers: Two independent 50A MPPT trackers (100A total solar charge current) support flexible solar array configurations, mixed orientations, and maximum energy harvesting with MPPT efficiency up to 98%.
• 4ms Ultra-Fast Transfer Switch: Switches to battery power in under 4ms during a grid outage fast enough to maintain uninterrupted operation of sensitive electronics, computers, and critical loads without a noticeable power interruption.
• Scalable Parallel & Three-Phase Operation: Supports parallel connection of up to 3 units for single-phase systems or up to 9 units for three-phase applications delivering a maximum combined output of 72KVA for larger installations.
• ESS & Peak Shaving Ready: Integrates with the TBB E4 LCD Monitor for advanced energy storage system features including peak shaving, time-of-use energy management, and self-consumption optimisation.
• AGS Generator Control: Automatic Generator Start function activates the generator only when solar and battery power are insufficient — minimising fuel consumption and automating hybrid energy management.
• ECO Mode: Reduces inverter standby power consumption during periods of low load, extending battery backup time and minimising energy waste.

Why Choose TBB Solar Inverter?

Most solar installations require separate devices for inverting, charging, and switching but this inverter eliminates all of that in a single transformer-based unit. Its heavy-duty transformer core handles surge loads at 300% rated power — pumps, compressors, and motor-driven appliances that lighter switchmode inverters struggle with. Dual MPPT trackers deliver 100A total solar charging, the 4ms transfer switch keeps critical electronics running without interruption, and parallel support across up to 9 units means the system scales to 72KVA without replacing any hardware. One unit. Real-world reliability. Room to grow.
