Sigenergy LoadHub
The Sigenergy Load Hub is an intelligent load management device designed to optimize how energy is distributed throughout a home or building. Acting as a central control point within the Sigenergy ecosystem, the Load Hub enables precise monitoring and prioritization of electrical loads, ensuring critical circuits remain powered during outages while balancing overall system demand. It works seamlessly with Sigenergy solar, battery storage, and EV charging solutions to maximize renewable energy usage and improve system efficiency. By enabling smart load shedding, peak demand management, and time-of-use optimization, the Load Hub helps reduce electricity costs and enhance energy resilience. Designed for safe and streamlined installation in North American electrical systems, it provides real-time visibility and control through Sigenergy’s connected energy platform. The result is a smarter, more responsive energy system that adapts to household needs automatically.

1. This refers to the load-side disruption time, to achieve this function Sigen LoadHub needs to be used together with Sigen Energy Controller US and Sigen Battery US. Test conditions: In the open-circuit state of the power grid, the nominal power of the Sigen Energy Controller US is higher than the total power of the home loads.
2. The MID Switch complies with UL Category NRNT2 and fulfills with the standards of UL 508, UL 60947-1, UL 60947-4-1, UL 61810-1 as well as UL 61810-20.
