Description

 

RiioSun II 3 kVA Solar Hybrid Inverter

The RiioSun II 3 kVA is a high-performance, transformer-based all-in-one solar hybrid inverter, built for backup power, off-grid systems, and Energy Storage System (ESS) applications. This compact powerhouse combines a pure sine wave inverter, battery charger, and a rapid-transfer UPS, providing seamless, reliable energy management.

Key Features

Versatile Power & Design

  • All-in-One Compact Design: Integrates inverter, charger, MPPT, and automatic transfer switch for easy installation and streamlined operation.

  • Built-In Rapid Transfer: 4 ms transfer time (2 ms UPS-level in some models), ensuring continuous power to critical loads during outages. 

Smart Energy Management

  • Programmable Smart Port: Configurable for generator input or secondary AC output to support load management or backup strategies (in 5/6 kVA models; includes similar smart management features in 3 kVA). 

  • Solid ESS Capabilities: Supports self-consumption, peak shaving, time-of-use optimisation, and grid feed-in/functionality—depending on local regulations. 

Durable & Expandable

  • Transformer-based design handles high surge (200–300%) loads—great for heavy appliances. 

  • Parallel & Three-phase Expansion: Combine up to 9 units to scale output to 54 kVA or higher.

  • Optional Battery-Less Operation: Can run directly from solar + grid in systems with stable AC bypass, reducing initial cost.

Monitoring & Support

  • Bluetooth & App Monitoring: Use TBB Nova App, Nova Web, or the local E4 LCD monitor for remote monitoring and control. 

  • ECO Mode: Extends backup duration by minimising self-consumption and efficiently managing power. 

Why Choose the RiioSun II 3 kVA?

  • Streamlined installation with robust design: Ideal for off-grid settings seeking reliable backup and off-grid operation.

  • Smart energy control: Supports sophisticated ESS functionality and load management tailored to self-sufficiency and cost savings.

  • Built to scale: Future-proof design allows expansion as energy needs grow.
