Fox ESS H3-PRO-15.0 15kW Inverter: The High-Capacity Three-Phase Hybrid Solar Inverter

The Fox ESS H3-PRO-15.0 is a powerful 15kW three-phase hybrid solar inverter, engineered for substantial residential properties or small commercial applications with three-phase power. This advanced inverter intelligently manages energy flows between your solar panels, the grid, and compatible high voltage storage batteries. Maximise your solar energy usage, reduce operating costs, and ensure power continuity with this sophisticated energy hub.

Superior Energy Harvest with Triple MPPT

Designed for large and potentially complex solar installations, the H3-PRO-15.0 features three independent Maximum Power Point Trackers (MPPTs). This configuration, detailed in the product datasheet, provides outstanding flexibility, allowing optimisation across multiple roof orientations or areas affected by shading, ensuring maximum power extraction from extensive solar panel arrays.

Seamless High-Voltage Battery Integration

As a cutting-edge hybrid inverter, the H3-PRO-15.0 works directly with compatible high-voltage LFP solar batteries (150-800V range). The technical specifications highlight its impressive battery handling capabilities, featuring dual battery inputs and a high combined charge/discharge current (50A+50A). This enables efficient battery energy storage, allowing you to store vast amounts of surplus solar energy for use when needed, significantly boosting self-consumption.

Optimised for Efficiency & Tariff Savings

Reduce your reliance on grid imports effectively. The H3-PRO-15.0 boasts high conversion efficiency (up to 97.8% Max. Efficiency according to the datasheet). By intelligently storing and deploying energy, it helps minimise grid usage, especially during peak price periods. Its smart controls can potentially be configured to leverage time-of-use tariffs, enabling battery charging from the grid during cheaper off-peak hours for even greater savings.

Powerful Three-Phase Backup Power (EPS)

Ensure continuity for critical loads during power cuts. When paired with compatible batteries, the H3-PRO-15.0 provides a robust 15kVA three-phase Emergency Power Supply (EPS) output. The manufacturer's information notes a rapid switchover time (<20ms), ensuring near-seamless power for essential three-phase or single-phase circuits during grid outages.

Built for Performance & Monitoring

Engineered for durability, the H3-PRO-15.0 features an IP65 rating, suitable for outdoor deployment with appropriate solar cabling and solar mounting systems. It utilises smart fan cooling for optimal performance. Comprehensive system monitoring is available via the Fox ESS Cloud platform using optional WiFi, 4G, or LAN modules, allowing remote tracking of energy generation, storage, and consumption.
