About This Product

The Sigenergy 20kW SigenStor Three Phase Controller is a 20kW three-phase hybrid energy controller designed to manage solar PV generation, SigenStor battery storage and grid interaction within the Sigenergy energy platform. The Australian model is SigenStor EC 20.0 TP AU and provides four independent MPPT trackers for connecting multiple PV strings or roof orientations.

It supports direct connection to compatible SigenStor battery modules and can form part of a grid-connected or backup-capable system when installed with the appropriate Sigenergy equipment. The controller has an IP66 enclosure rating and includes integrated communications and electrical protection functions suited to Australian residential and commercial installations.

Who This Product Suits

The Sigenergy 20kW SigenStor Three Phase Controller suits larger three-phase homes, small commercial sites and other installations requiring substantial solar inverter capacity with the option of battery storage.

Its four MPPT inputs make it particularly useful for PV arrays spread across several roof orientations or electrically separate array sections. It is also suited to customers planning a complete SigenStor system where solar, battery storage, monitoring and optional backup operation are managed through the same platform.

Specifications Explained

• 20kW nominal AC output: Provides up to 20,000W nominal three-phase grid output.
• 32kW maximum PV input: Supports a maximum connected PV power of 32,000W, allowing suitable oversizing of the solar array.
• Four MPPT trackers: Four independent maximum power point trackers provide flexibility when designing arrays with different orientations or operating conditions.
• 1100V maximum DC input: Supports high-voltage PV string design, with a nominal DC input voltage of 600V.
• 160-1000V MPPT range: Provides a broad operating voltage window for compatible solar array configurations.
• 98.3% maximum efficiency: High conversion efficiency helps minimise inverter losses during normal solar operation.
• SigenStor battery support: Compatible with SigenStor BAT 5.0 and BAT 8.0 battery modules, with one to six battery modules supported per controller.
• Backup capability: Supports three-phase backup operation when incorporated into a correctly configured Sigenergy system with the required gateway equipment.
• IP66 protection: The enclosure is protected against dust ingress and strong water jets, allowing suitable indoor or outdoor installation locations.
• Integrated communications: Supports WLAN, Fast Ethernet, RS485 and compatible Sigen communication hardware for commissioning, monitoring and system integration.
• Built-in protection: Includes DC reverse-polarity protection, insulation monitoring, residual-current monitoring, arc-fault protection, anti-islanding and Type II AC/DC surge protection.

Summary

The Sigenergy 20kW SigenStor Three Phase Controller is a high-capacity three-phase hybrid controller for solar and battery installations requiring up to 20kW nominal AC output. Its 32kW maximum PV input, four MPPT trackers, broad PV operating range and direct compatibility with SigenStor battery modules make it suitable for larger residential and commercial energy systems.

For installations built around the Sigenergy platform, it provides the central conversion and control hardware for integrating PV generation, battery storage, monitoring and compatible backup functions.
