Hybrid Inverter Fox ESS P3-50-Plus (50 kW, 3 Phases, High-Voltage)

A commercial-grade three-phase hybrid inverter from the Plus series with a 50 kW capacity. This is a powerful and reliable solution from Fox ESS, engineered specifically for small, medium, and large businesses. The inverter allows enterprises to substantially cut electricity costs, export surplus power back to the utility grid, and guarantees the uninterrupted operation of manufacturing or commercial equipment by working with high-voltage (HV) industrial battery storage systems.

Advantages:

• Commercial-Grade Power (50 kW): Ensures stable power supply for production lines, large office centers, restaurants, warehouses, and supermarkets.

• 4 Independent MPPT Trackers: Allow for the maximum utilization of large, complex roof structures by enabling solar panels to face four distinct directions.

• Massive Solar Array Support (Up to 75 kW): Supports up to 150% PV oversizing. This guarantees that your business harvests the maximum amount of free energy from early morning until late evening.

• 100% Unbalanced Phase Load Support: Intelligent energy distribution. The inverter is capable of directing all required power to the heaviest-loaded phase without any risk of system faults or imbalances.

• Scalability for Business: Supports the parallel connection of multiple units to build massive commercial-scale solar plants (up to 500+ kW).

• Instant Backup Power (EPS): In the event of a utility grid blackout, the facility automatically transitions to battery power, preventing downtime in operational processes and safeguarding against data loss.

Ideal For:

• Medium-sized businesses: supermarkets, hotels, restaurants, logistics warehouses, and auto repair shops.

• Manufacturing enterprises where preventing operational downtime during blackouts is critical.

• The agricultural sector: farms, commercial greenhouses, and poultry facilities.

• Ultra-large private estates and residences with exceptionally high energy consumption profiles.

Technical Specifications:

• Nominal Output Power: 50 kW

• Max. Solar Array Power: 75.0 kW (up to 150% PV oversized)

• Phase Layout: 3-Phase (Three-Phase)

• Battery Compatibility: High-Voltage (HV) Li-ion

• Warranty Policy: 10-year standard manufacturer warranty

Explanation of Terms:

• Commercial & Industrial Station (C&I) – A solar power system dedicated to meeting the energy demands of businesses, cutting operational electricity expenses, and enhancing corporate energy independence.

• Unbalanced Phase Load – The capacity of the inverter to flexibly distribute output power across the three lines. It is vital for facilities where the electrical load on individual phases changes dynamically.

• High-Voltage (HV) Battery – The industrial standard for energy storage systems. It allows for the management of massive power volumes with minimal thermal losses through cabling.
