Fox ESS H3-PRO-30.0 30kW Inverter: The Flagship Three-Phase Hybrid Solar Inverter for Maximum Power

The Fox ESS H3-PRO-30.0 represents the pinnacle of the H3 Pro series, delivering a massive 30kW of three-phase hybrid inverter power. Engineered for large commercial and industrial applications, this unit offers unparalleled capability in managing vast solar panel systems, extensive high voltage battery storage banks, and complex grid interactions. Achieve ultimate energy control, minimise operational costs, and ensure robust power continuity with this top-of-the-line inverter.

Maximum Yield from Extensive Solar Arrays via Triple MPPT

Designed for the largest solar installations, the H3-PRO-30.0 utilises three independent Maximum Power Point Trackers (MPPTs). This feature, outlined in the technical datasheet, provides exceptional design flexibility, accommodating arrays spread across multiple large roof areas or facing different directions. Each MPPT optimises performance for its connected strings (up to 15kW DC input per MPPT recommended), guaranteeing the maximum possible energy harvest from your entire large-scale solar panel system.

High-Power Battery Energy Storage Integration

What size inverter handles industrial-scale storage? The H3-PRO-30.0 is built for significant battery energy storage needs. It directly integrates with compatible high-voltage LFP batteries (150-800V range) and, according to the product specifications, supports substantial energy throughput with dual battery inputs and a combined 50A+50A maximum charge/discharge current. This facilitates efficient management of very large battery banks essential for commercial-level energy independence.

Peak Efficiency for Commercial Savings

Operational efficiency translates to cost savings. The H3-PRO-30.0 operates at impressive efficiency levels (up to 97.80% Max. Efficiency cited in the specs). By maximising the use of on-site generated solar power and stored energy, it drastically cuts reliance on grid electricity during expensive peak periods. Its advanced controls also enable sophisticated energy arbitrage strategies, potentially charging batteries using low-cost off-peak grid power for discharge during high-cost periods.

Industrial-Grade Backup Power (EPS)

Protect critical operations from grid downtime. When paired with an appropriately sized battery bank, the H3-PRO-30.0 delivers an industrial-strength 30kVA three-phase Emergency Power Supply (EPS) output. The datasheet confirms a near-instantaneous switchover (<20ms), ensuring critical machinery, IT infrastructure, or building systems remain powered during grid failures.

Robust Construction & Advanced Monitoring

The H3-PRO-30.0 features a durable IP65-rated enclosure suitable for challenging environments (ensure installation with correct cabling and mounting). Smart fan cooling maintains optimal performance under sustained high loads. Facility managers can leverage the Fox ESS Cloud platform (via optional WiFi, 4G, or LAN modules) for in-depth remote monitoring and management of the entire energy ecosystem.
