All-in-one hybrid design

The SkyBox SBX5048-120/240 combines a grid-tied inverter, battery inverter, and charge controller into one streamlined unit. Its transformerless, ungrounded design supports up to 600V PV input and eliminates the need for external components such as charge controllers or communication boxes—cutting installation time and system complexity. This integrated approach makes SkyBox ideal for solar storage projects where flexibility and scalability are key.

Smarter energy management

SkyBox intelligently manages power flow between the grid, solar array, batteries, generator, and home loads. It supports time-of-use optimization, net metering, and non-export modes to maximize energy independence and savings. The inverter also provides 5,000 VA of continuous power with seamless backup capability and meets all UL 1741 SA, CA Rule 21, and HECO Rule 14H standards for advanced grid interaction.

Future-ready with battery flexibility

Not ready for batteries? Install SkyBox now as a high-efficiency grid-tied inverter and easily add energy storage later—no rewiring or retrofitting required. Compatible with a wide range of 48V battery chemistries, including lithium-ion, SkyBox adapts to evolving energy needs and technologies, offering long-term investment protection and system scalability.

Built to last
