Sigenergy LoadHub 200A Backup Power System
SKU SIG-SIGEN-LOADHUB
The Sigenergy LoadHub is a professional-grade backup power management system engineered for seamless integration with SigenStor energy storage units. This 200-amp split-phase system delivers 0ms load-side disruption during grid outages through Sigenergy's patented power control algorithm, ensuring continuous power supply to critical loads without interruption. The system supports connection of up to 2 SigenStor units with 48A continuous current capacity per connection, providing scalable backup energy solutions for residential and light commercial applications. Operating on 120/240V split-phase configuration with 60Hz nominal frequency, the LoadHub manages bidirectional power flow between grid, solar, storage, and generator sources with precision current and voltage measurement accuracy of ≤1%.
TThe LoadHub incorporates advanced energy management features including 5 smart load ports with 64A continuous current capacity, generator integration with 2-wire start capability, and comprehensive system monitoring through the mySigen mobile application.
Sigen LoadHub Features
- Instantaneous Backup Transition: Patented 0ms load-side disruption technology maintains continuous power to all connected loads during grid failures, eliminating equipment shutdowns and protecting sensitive electronics
- Advanced Protection Systems: Industry-leading 350ms reverse power flow protection with bypass switch support and data-driven risk prevention mechanisms safeguard equipment and personnel
- Flexible Load Management: Five independent smart load ports with 64A continuous current capacity enable prioritized backup power distribution and remote control through mySigen App
- Ultra-Quiet Operation: Natural convection cooling maintains system noise below 25dB, suitable for residential installations without acoustic disruption
- Precision Monitoring: ≤1% current and voltage measurement accuracy with real-time data transmission via Fast Ethernet, RS485, and dry contact communication protocols

Sigenergy Sigen LoadHub Technical Review
Unlike traditional automatic transfer switches that introduce 10-100ms switching delays, the LoadHub's patented power control algorithm maintains continuous voltage and frequency during grid transitions, preventing nuisance trips in sensitive electronic equipment and motor loads. The 200-amp continuous current rating across both grid and distribution panel connections accommodates whole-home backup applications, while the dual SigenStor connection capability with 48A per port supports up to 23kW of inverter capacity (2 × 11.5kW). The five independent smart load ports provide granular control over critical and non-critical loads, enabling battery runtime optimization through selective load shedding strategies. Generator integration via 2-wire start with 64A continuous rating extends backup duration for prolonged outage scenarios, with intelligent starting logic minimizing fuel consumption through battery-first operation.
