Key Features:

• Comprehensive all-in-one design: The RIIO SUN II combines multiple functionalities into one compact casing, including a pure sine wave inverter, two advanced MPPT solar charge controllers, and an efficient battery AC charger. This design offers simple installation and optimises performance in various applications.
• High surge capacity: Engineered to handle significant surge loads, the RIIO SUN II guarantees uninterrupted running of essential appliances during power outages, for off-grid living or as a backup scenario. With a swift 4ms transfer time, it quickly switches to battery power during outages, ensuring your critical appliances continue running.
• Enhanced flexibility: The RIIO SUN II can be configured in parallel with up to 3 units in single-phase applications, or up to 9 units in three-phase applications, achieving a maximum output of 72KVA. This feature is ideal for larger installations with higher power demands.
• Dual MPPT technology: Equipped with two MPPT trackers, the inverter supports flexible system design, allowing for efficient energy harvesting from multiple solar arrays. With a maximum PV open circuit voltage of up to 250V, it optimises energy yields, ensuring reliable and consistent performance for various installation scenarios.
• ESS capabilities: The RIIO SUN II inverter seamlessly integrates with the E4 LCD Monitor and IC-METER (sold on request), unlocking advanced Energy Storage System (ESS) functionalities. This maximises self-consumption, which helps lower electricity bills through advanced peak shaving and time-of-use management.
• 50A transfer switch: The AC transfer switch in the RIIO SUN II is rated up to 50A, allowing for up to 11.5kW of power to be passed through to the loads from the AC input when the inverter is in bypass.

Additional Intelligent Features:

• AGS functionality: The Automatic Generator Start (AGS) function ensures efficient operation by activating the generator only when necessary, optimising energy use.
• Power assist and control for generators: Power assist enables a small generator to handle heavy loads by supplementing its capacity when needed. Power control ensures the generator operates at its optimal consumption level, maintaining a consistent output to reduce significantly fuel consumption.
• User-friendly monitoring: Users can monitor performance through the Nova Web and mobile app via the TBB-KIN2 Kinergy-II Wi-Fi module, controlling and making adjustments from anywhere.
• Reliable operation: The inverter features a 4ms ultra-fast switch to battery power, ensuring swift response during power interruptions. Additionally, it operates in an ECO Mode, which extends backup time while maintaining low self-consumption.
• Superior efficiency: With a maximum MPPT efficiency of 98% and a maximum inverter efficiency of 94%, the RIIO SUN II delivers optimal performance, maximising energy capture and utilisation.
• Easy operation & maintenance: The all-in-one design offers straightforward installation and maintenance, ensuring hassle-free operation. The inverter automatically restarts when PV or AC power is restored, guaranteeing continuous availability of energy.
