RIIO SUN-II 5KVA/48V SOLAR INVERTER 250V/100A-TBB

Description

The TBB RiiO Sun II 5KVA/48V is a versatile all-in-one transformer-based hybrid solar inverter for backup power, off-grid, and ESS applications. It combines a pure sine wave inverter, 60A AC battery charger, dual MPPT solar charge controllers, and a 4ms automatic transfer switch in a single compact unit. The transformer-based design delivers robust surge handling at 300% rated power — making it reliable for heavy loads and motor-driven appliances. With a programmable smart port, battery-optional operation, and support for parallel and three-phase configurations across up to 9 units, the 5KVA is a capable, scalable entry point into the RiiO Sun II ecosystem.

Key Features

• All-in-One Design: Integrates a pure sine wave inverter, dual MPPT solar charge controllers, a 60A 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 MPPT trackers 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 45KVA 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 higher output power without replacing any hardware. One unit. Real-world reliability. Room to grow.
