SolarEdge SE-90K-FUSE-FULL Synergy Three Phase Inverter – 90kW

SolarEdge SE-90K-FUSE-FULL: The Scalable Commercial Inverter for High-Yield Energy Systems

Built for substantial solar installations, the SE-90K-FUSE-FULL consists of three SESUK-RWR0INNN4 Synergy power modules and one SE90K-RW00IBNE4 manager unit. Its modular approach streamlines deployment and serviceability, offering enhanced system reliability and ease of operation for large-scale commercial projects.

Engineered for large-scale commercial PV installations, the SolarEdge SE-90K-FUSE-FULL delivers 90kW of high-efficiency three-phase output with modular design benefits. It consists of three independent Synergy power modules and a central control unit, optimising performance, serviceability and safety in high-demand environments.

This powerful inverter is designed for ease of transport, fast commissioning, and seamless integration with SolarEdge optimisers, offering unmatched visibility and flexibility for long-term commercial performance.

Modular Design for Simplified Installation

With its Synergy architecture, the SE-90K inverter splits into multiple lightweight units, one control and three Synergy modules, making transportation and mounting significantly easier than traditional high-capacity inverters. This layout reduces installation time, simplifies servicing, and supports flexible mounting options across commercial rooftops or plant rooms.

• Independent module servicing minimises system downtime
• Integrated commissioning tool via built-in LCD and app
• Optimised for large sites needing phased scalability

Grid Resilience and Safety Built In

According to the datasheet, the SE-90K-FUSE-FULL includes optional integrated AC and DC Type 2 SPDs, an accessible AC switch, and rapid shutdown capabilities. These features make it fully compliant with G99 regulations and aligned with the latest commercial site standards across the UK.

• Complies with UK grid standards and safety codes
• DC and AC surge protection supports grid-tied stability
• Module-level shutdown and arc fault protection enhance safety

Unmatched Efficiency and Performance

Offering a peak efficiency of 98.3% and designed for optimal integration with SolarEdge’s high-resolution monitoring platform, the SE-90K-FUSE-FULL ensures consistent output across varying irradiance and load conditions. It supports oversizing on the DC input side, maximising generation throughout the year.

Why Evergy Recommends This Product
