Common Questions What battery types are compatible with this inverter? The TBB Power RIIOSUN-II is compatible with a wide range of 12V battery types, including lead-acid (AGM, GEL, Flooded) and various lithium batteries (e.g., LiFePO₄) with appropriate BMS. Can this inverter operate without a battery? Yes, the RIIOSUN-II can operate without a battery, but this configuration is typically for single-use applications with a stable AC bypass supply, where PV energy supplements the AC bypass. Is it possible to expand the system capacity later? Yes, the RIIOSUN-II offers enhanced flexibility, allowing parallel connection of up to 3 units in single-phase applications or up to 9 units in three-phase applications for increased power output. What is the transfer time during a power outage? The inverter features a rapid 4ms automatic transfer switch, ensuring a near-instantaneous switch to battery power to maintain continuous operation of critical loads. Installation Notes Installation should be performed by a qualified professional in accordance with local electrical regulations and the manufacturer's manual. Ensure adequate ventilation around the inverter to prevent overheating and maintain optimal performance. Verify correct battery voltage (12V) and type compatibility before connecting to the inverter. Proper grounding is essential for safety and system stability. Consider the inverter's IP21 rating, which indicates protection against solid objects over 12.5mm and vertically falling drops of water. It is not suitable for outdoor exposure without additional protection. Before You Buy Confirm your total load requirements (continuous and surge) to ensure the 1kW continuous and 2kW peak power output meets your needs. Check your battery bank's nominal voltage to ensure it is 12V for compatibility with this inverter. Assess your solar array's specifications (Max PV Open Circuit Voltage 150V, MPPT Voltage Range 30-145V) to ensure it aligns with the inverter's MPPT controller. Consider future expansion needs; this model supports parallel operation for increased capacity. Review the physical dimensions (462 x 255 x 144 mm) and weight (12 kg) to ensure suitable mounting space. Always verify product specifications and compatibility with your existing system components before purchase. This product is covered by a 5-year manufacturer warranty.
