TBB Riiosun II 3kVA 48V Hybrid Solar Inverter

The TBB Riiosun II 3kVA 48V Hybrid Solar Inverter is a versatile, high-performance power solution tailored for modern off-grid and hybrid solar power systems. Built to support residential and small commercial installations, this hybrid inverter combines intelligent energy management, robust performance, and long-lasting reliability in a compact, easy-to-install design.

At the heart of the Riiosun II is a true sine-wave inverter capable of delivering up to 3000 VA (3 kVA) of continuous AC power from a 48V battery bank. Designed to power a wide range of household and office loads—including LED lighting, TVs, computers, refrigerators, pumps, and small appliances—this unit ensures clean, stable energy without electrical noise or distortion, keeping sensitive electronics safe and efficient.

As a hybrid solar inverter, the Riiosun II intelligently manages power flows from multiple energy sources: solar panels, batteries, and utility or generator input (if available). During periods of strong sunlight, solar energy is prioritized to power loads and charge the connected battery bank through built-in MPPT (Maximum Power Point Tracking) solar charge controllers, which optimize PV array performance for maximum energy harvest even in changing light conditions.

When solar energy alone is insufficient—as in cloudy weather or at night—the unit seamlessly draws energy from the battery bank to maintain uninterrupted power delivery. In grid-hybrid configurations, it can also pull from the utility or generator as required, providing peace of mind in locations with unstable grid supply.

Engineered for flexibility, the TBB Riiosun II supports various battery types, including high-quality lead-acid, GEL, AGM, and lithium batteries (with appropriate configuration), supporting deep discharge and efficient charging. Its robust battery charging algorithm helps extend battery life and improve cycle performance.

The inverter’s LCD display and intuitive user interface provide real-time insights into system status, including battery voltage, solar input, load output, operating modes, and fault notifications, making system monitoring straightforward for homeowners and technicians alike.

Safety and durability are built-in features. The system includes overload protection, short-circuit protection, reverse polarity protection, over-temperature shutdown, and DC/AC voltage safeguards, ensuring stable operation under various conditions. Its rugged construction and efficient cooling design make it suitable for indoor or covered outdoor installations.

Whether you’re powering a small home, remote cabin, workshop, or small business, the TBB Riiosun II 3kVA 48V Hybrid Solar Inverter offers dependable performance, smart energy management, and reliable backup power in one intelligent package.
