Sunboost Split Phase Solar Inverter 8KW 10KW 12KW 15KW Hybrid Inverter 3 MPPTs Low Voltage Parallel Up to 6 Units

This characteristic encompasses the inverter's robust capability to handle substantial power flows while ensuring continuous operation during grid disturbances. The system supports a maximum charge and discharge current of 275A, enabling rapid energy transfer to and from the battery bank. This high-current capacity is essential for demanding applications such as whole-home backup, commercial load shifting, and heavy equipment operation, ensuring that the battery can be quickly recharged when solar energy is available and can deliver sustained power during peak demand periods. Complementing this high-power capability is the inverter's UPS-level switching performance, achieving a seamless transfer time of less than 10 milliseconds when transitioning from grid power to battery backup. This ultra-fast switching ensures that sensitive electronic equipment—including computers, medical devices, networking gear, and home automation systems—experiences no interruption during grid outages. For applications where continuous operation is critical, this feature provides true uninterruptible power supply functionality, maintaining business continuity and preserving data integrity without the need for additional external UPS devices.

This feature set defines the inverter's exceptional ability to integrate with existing infrastructure and scale with growing energy demands. The system is AC-coupling ready, allowing for straightforward retrofitting into existing solar installations without requiring system rebuilds. This capability is particularly valuable for customers who already have grid-tied solar arrays and wish to add battery storage functionality. By connecting at the AC side, the inverter can work alongside existing PV systems, storing excess solar energy that would otherwise be exported to the grid and making it available for self-consumption or backup power. For system expansion, the inverter supports three-phase parallel operation with up to 6 units. This scalable architecture enables power capacity to grow incrementally from a single unit to a multi-unit configuration, accommodating increasing energy demands without replacing existing equipment. The parallel configuration maintains synchronized phase coordination and balanced load sharing across all connected units, delivering the reliability and redundancy required for commercial and industrial applications. The inverter further enhances system flexibility through dual AC ports, separately accommodating grid connection, generator input, and smart load management. This design allows for prioritized load control, enabling critical circuits to remain powered during outages while non-essential loads can be shed automatically. The dedicated generator input supports integration with backup generators, creating a comprehensive hybrid power system that combines solar, battery storage, and generator backup under unified control.

This characteristic addresses the inverter's physical resilience and long-term reliability in challenging installation conditions. The unit is housed in a NEMA 4X-rated enclosure, providing comprehensive protection against environmental hazards. This rating signifies the inverter is fully sealed against dust ingress, water penetration from hose-directed spray or heavy rain, and corrosion resistance suitable for outdoor and industrial applications. The NEMA 4X construction makes the inverter suitable for installation in locations where standard electronic equipment would be at risk—including coastal areas with salt spray exposure, agricultural environments with ammonia and chemical exposure, food processing facilities requiring wash-down capability, and outdoor installations exposed to direct weather. The corrosion-resistant enclosure ensures long-term protection of internal components, maintaining operational reliability and extending service life even in demanding conditions. By eliminating the need for indoor installation or protective shelters, this rugged construction reduces installation costs and expands deployment possibilities, allowing the inverter to be placed closer to the point of use—whether on exterior walls, in equipment yards, or within industrial facilities—without compromising system integrity.
