About This Product

The Sigenergy 15kW SigenStor Three Phase Controller is a three-phase energy controller designed for solar plus battery storage installations. It integrates inverter functionality, an energy management system (EMS), and hybrid battery support to manage generation, storage and grid or off-grid supply in one unit. It supports direct DC input from solar arrays, coordinates battery modules, and delivers AC output appropriate for three-phase supply ‘ making it a core component in a complete storage-ready solar system.

Who This Product Suits

This controller is ideal for residential or small commercial sites with a three-phase electrical supply, especially where you plan to combine solar generation and battery storage from day one. It suits homeowners or businesses looking for a robust, integrated solution to manage solar, battery and grid interaction ‘ including off-grid or backup-capable setups. It also works well for systems expecting future expansion or higher loads, thanks to its hybrid controller design and three-phase output.

Specifications Explained

• Built-in EMS: Integrated energy management system enables precise control of solar input, battery storage and AC output ‘ optimising generation usage and battery charging/discharging.
• Three-phase output (15 kW): Delivers balanced three-phase power, suitable for three-phase electrical supply in homes or light commercial premises.
• Hybrid ready (battery integration): Designed to work with compatible battery modules from the same family, enabling a full solar + storage solution rather than just a solar inverter.
• On-grid and off-grid compatible / black-start capable: System supports grid-tied operation and can also operate or restart from battery/solar supply in an off-grid or blackout scenario.
• DC ground-fault protection and safety features: Built-in protection against DC ground faults, plus standard inverter protections (anti-islanding, surge protection, over-current/voltage, etc.), for safe and compliant installation.
• Durable enclosure (IP66): Weather-resistant housing allows for indoor or outdoor installation, protecting internal electronics from dust and water ingress.

Summary

The Sigenergy 15kW SigenStor Three Phase Controller is a flexible, hybrid-ready energy controller that combines inverter, storage-management and grid/off-grid capability in a single unit. Its three-phase, 15 kW output, integrated EMS, and safety protections make it a solid choice for homes or small businesses aiming for a solar + battery setup. If you want a streamlined, expandable system that can handle solar generation, battery storage and provide reliable three-phase power ‘ this controller offers a complete foundation.
