SolarEdge SE-66.6K-FUSE-FULL Synergy Three Phase Inverter – 66.6kW

SolarEdge SE-66.6K-FUSE-FULL: The Scalable Commercial Inverter for High-Demand PV Systems

This commercial three-phase inverter system comprises two SESUK-RWR0INNN4 Synergy power modules and one SE66.6K-RW00IBNE4 manager unit. These modules work seamlessly together to deliver reliable, scalable 66.6kW output, simplifying installation and maintenance through modular flexibility.

The SolarEdge SE-66.6K-FUSE-FULL is a powerful three-phase inverter system built for large commercial applications. With its modular Synergy architecture, featuring separate Synergy Units and a dedicated Manager Unit, it simplifies transport, installation, and maintenance without compromising on power or safety. Offering 66.6kW of output and a full suite of integrated protections, it's an ideal solution for businesses seeking maximum efficiency and reliability in their solar investment.

Modular Design for Easier Deployment

Rather than relying on a bulky single-unit setup, this inverter separates into two Synergy Units and one Manager Unit, making installation more manageable, especially in retrofit or space-constrained sites. Each unit is lightweight enough for two-person handling and can be wall- or floor-mounted to suit your site layout.

• Flexible mounting options (wall/floor)
• Streamlined system servicing and part replacement
• Rapid deployment across commercial rooftops or ground arrays

Built-In Safety and Protection

As detailed in the datasheet, the SE-66.6K-FUSE-FULL includes an integrated DC Safety Unit with arc fault detection, rapid shutdown, and optional AC/DC Type 2 surge protection. This significantly reduces risk while meeting the latest commercial compliance standards in the UK and EU.

High Efficiency with Maximum Yield

With a weighted efficiency of up to 98.3% and fixed string voltage, the inverter ensures stable output across a range of irradiance conditions. It’s also fully compatible with SolarEdge power optimisers for module-level monitoring and increased energy harvest from each panel.

Monitoring and Smart Integration

This Synergy inverter includes full visibility over system performance via the SolarEdge monitoring platform, enabling remote diagnostics and real-time insights into each string or module. This not only supports maintenance but enhances ROI through data-driven optimisation.

• Remote troubleshooting and alerts
• Module-level data granularity
• Compatible with Building Management Systems (BMS)
