All-in-one hybrid energy solution

The SkyBox SBX5048-120/240 combines the functionality of a grid-tied inverter, battery inverter, and charge controller into a single enclosure. It manages power flow between solar arrays, energy storage, the utility grid, and loads—optimizing how energy is generated, consumed, stored, and exported. With its high PV input voltage (up to 600V) and transformerless design, SkyBox allows long string configurations and efficient system layouts.

Smart energy control and flexibility

SkyBox offers user-selectable modes for self-consumption, backup power, non-export operation, and time-of-use management. It intelligently prioritizes renewable energy use and supports configurable battery charging from AC or solar sources. The inverter complies with California Rule 21 and Hawaii Rule 14H, providing advanced grid support features and maximum operational flexibility.

Resilient and ready for storage

Not ready to add batteries? Install SkyBox as a grid-tied inverter today and add energy storage later without retrofitting your solar system. Once batteries are connected, the inverter provides 5,000 VA of backup power and instantaneous transition during grid outages, ensuring reliable energy supply and peace of mind.

Reliable performance and easy installation

Built to last, SkyBox features NEMA 3R weather protection for indoor or outdoor use and operates in temperatures from -20°C to 60°C. Extensive testing, including Highly Accelerated Life Testing (HALT), ensures long-term reliability. Installation is fast and simple, with all major components pre-integrated into one enclosure—minimizing wiring, labor, and system complexity.
