Hybrid Inverter Fox ESS P3-Pro-20.0 (20 kW, 3 Phases, High-Voltage)

Commercial-grade power and premium reliability in a compact enclosure. The 20 kW three-phase hybrid inverter from the Fox ESS PRO series is a flagship solution designed for large households, complex roofs, and commercial facilities. Featuring compatibility with high-voltage (HV) batteries, 100% unbalanced phase load support, and three independent MPPT trackers, this inverter enables the construction of a highly efficient and flexible energy ecosystem.

Advantages:

• Commercial-Grade Power (20 kW): Effortlessly handles heavy-duty three-phase equipment: industrial refrigerators, servers, manufacturing machinery, climate control systems, and high-speed EV chargers.

• 3 Independent MPPTs (6 Inputs): A unique feature for complex roof layouts. It allows the connection of 3 distinct solar panel groups (e.g., East, South, West). Each tracker features 2 inputs, enabling a total connection of up to 30 kW of solar arrays!

• 100% Unbalanced Phase Load Support: The inverter intelligently distributes energy. If the entire power demand is concentrated on a single phase, it redirects it there seamlessly, preventing phase imbalances, system faults, or overloads.

• High-Voltage (HV) System: Ensures ultra-fast charging of large battery banks and minimizes energy conversion losses.

• Seamless Backup Power (EPS): In the event of a blackout, switching to battery mode takes less than 20 milliseconds — ensuring servers and sensitive electronics continue running without rebooting.

• Scalability: Supports parallel connection of multiple inverters to increase the total capacity of the solar station (up to 10 units).

Ideal For:

• Large commercial facilities: supermarkets, office centers, auto repair shops, hotels, restaurants, and commercial agricultural farms.

• Large private villas and estates equipped with swimming pools, electric saunas, and multiple electric vehicles.

• Properties with complex roof architecture requiring 3 independent MPPT trackers.

• Station owners aiming to maximize profits by exporting electricity under the "Green Tariff" (Feed-in Tariff) program at commercial volumes.

Technical Specifications:

• Nominal Output Power: 20 kW

• Max. Solar Array Power: 30.0 kW (up to 150% PV oversizing allowed)

• Phase Layout: 3-Phase (Three-Phase)

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

• Number of MPPT Trackers: 3 (2 strings per tracker)

• Maximum Efficiency: Up to 98.1%

• Communication Interfaces: Wi-Fi, LAN, RS485, DRM

• Ingress Protection Rating: IP65 (Aluminum casing with active cooling infrastructure)

• Warranty Policy: 10-year standard manufacturer warranty

Explanation of Terms:

• 3 MPPT Trackers – A multi-tracker system that harvests energy from three different roof planes independently. If a cloud shades one section of the roof, the other two continue to harvest 100% of the available solar energy.

• Unbalanced Phase Load – The ability of the inverter to deliver varying power outputs to each of the three lines independently. A vital safety feature for commercial facilities to prevent emergency grid trips.

• Parallel Connection – The capacity to combine multiple units into a unified network to build a solar station with a total output of 40 kW, 60 kW, or up to 100+ kW.
