Fox ESS H3-PRO-25.0 25kW Inverter: The Commercial-Grade Three-Phase Hybrid Solar Inverter

The Fox ESS H3-PRO-25.0 stands as a formidable 25kW three-phase hybrid inverter, engineered for large residential estates, commercial buildings, or industrial facilities with substantial energy needs. This powerhouse unit provides sophisticated control over large solar panel installations, extensive high voltage battery storage banks, and grid interaction, enabling significant operational savings and energy resilience.

Triple MPPT for Large-Scale Solar Optimisation

Designed to handle vast solar arrays, the H3-PRO-25.0 incorporates three independent Maximum Power Point Trackers (MPPTs). This configuration, specified in the product datasheet, offers maximum flexibility in system design, perfectly suited for installations spread across large or multiple roof areas with varying orientations and potential shading issues. It ensures that the maximum possible power (up to 12.5kW DC input per MPPT recommended) is extracted from every part of your solar panel system.

High-Capacity Battery Storage Management

Choosing the correct type of inverter is critical for large battery energy storage. The H3-PRO-25.0 is built for this, directly managing compatible high-voltage LFP batteries (150-800V range). Its dual battery inputs and high combined charge/discharge current capability (50A+50A), detailed in the technical specifications, allow for efficient management of large battery banks. Store huge amounts of surplus solar energy and discharge rapidly to meet peak demands.

Peak Efficiency & Smart Energy Strategies

Minimise energy waste and maximise financial returns. The H3-PRO-25.0 operates at high efficiency levels (up to 97.80% Max. Efficiency noted in the documentation). By enabling massive solar self-consumption, it drastically reduces reliance on purchasing grid electricity. Furthermore, its intelligent controls allow for advanced energy strategies, including potentially optimising battery charging schedules based on dynamic or time-of-use tariffs for enhanced cost savings.

Substantial Three-Phase Backup Power

Protect your operations from costly power interruptions. When integrated with sufficient battery capacity, the H3-PRO-25.0 delivers a very substantial 25kVA three-phase Emergency Power Supply (EPS) output. With a swift changeover (<20ms according to the datasheet), it can keep essential large machinery, servers, or building services running smoothly during grid failures.

Durable Engineering & Comprehensive Monitoring

The H3-PRO-25.0 is IP65 rated, signifying its robustness for outdoor installations when using appropriate cabling and mounting. Smart fan cooling ensures reliable operation under load. Facility managers or owners can remotely monitor the entire system's performance via the Fox ESS Cloud platform (requires optional WiFi, 4G, or LAN module), accessing detailed data on generation, storage, and consumption patterns.
