Key features:

• Comprehensive all-in-one design: The RIIO SUN II integrates multiple functionalities into a compact unit, including a pure sine wave inverter, an advanced MPPT solar charge controller, and an efficient AC battery charger. This streamlined design simplifies installation while optimising performance across various applications.
• High surge capacity: Engineered to handle significant surge loads, the RIIO SUN II ensures uninterrupted operation of essential appliances during outages. Its rapid 4ms transfer switch guarantees a smooth transition to battery power for critical systems.
• Enhanced flexibility: The RIIO SUN II supports parallel configurations, allowing up to 3 units for single-phase setups or up to 9 units for three-phase applications, delivering a maximum output of 72KVA. This makes it ideal for larger installations requiring higher power output.
• Dual MPPT technology: Equipped with two MPPT trackers, the inverter enables flexible system design, allowing for efficient energy harvesting from multiple solar arrays. With a maximum PV open-circuit voltage of up to 250V, it maximises energy yields, ensuring reliable and consistent performance across a range of installation scenarios.
• ESS capabilities: The inverter integrates seamlessly with the E4 LCD Monitor and IC-METER (available on request), unlocking advanced ESS features. These enable peak shaving, time-of-use energy management, and maximised self-consumption, helping to lower electricity bills.
• 50A transfer switch: The built-in AC transfer switch, rated at up to 50A, allows up to 11.5kW of power to pass through from the AC input in bypass mode.

Additional intelligent features:

• AGS functionality: The Automatic Generator Start (AGS) activates the generator only when necessary, optimising fuel consumption and energy use.
• Power assist and control: Power assist supplements small generator capacity to handle heavy loads, while power control ensures the generator operates at optimal efficiency, reducing fuel consumption.
• User-friendly monitoring: The Nova Web and mobile app, accessible via the TBB-KIN2 Kinergy-II Wi-Fi module,  enable remote monitoring and adjustments from anywhere.
• Reliable operation: Features a 4ms ultra-fast switch to battery power for immediate response during interruptions, alongside an ECO Mode for extended backup time and low self-consumption.
• Superior efficiency: Achieves up to 98% MPPT efficiency and 91% inverter efficiency, ensuring maximum energy capture and utilisation.
• Easy operation & maintenance: The all-in-one design simplifies installation and maintenance. Automatic restart upon PV or AC power restoration ensures consistent energy availability.
