Hybrid Inverter Fox ESS P3-12.0-SH (12 kW, 3 Phases, High-Voltage)

A high-performance three-phase hybrid inverter with a 12 kW capacity. This is a reliable and flexible solution from the premium brand Fox ESS, engineered for large households and commercial properties. Thanks to its support for high-voltage (HV) batteries and its ability to handle unbalanced phase loads, this device ensures maximum autonomy and comfort even under complex energy consumption profiles.

Advantages:

• Asymmetric/Unbalanced Phase Load Support: Smart energy distribution. The inverter automatically directs the exact required amount of power to the phase that is currently under the heaviest load, preventing phase imbalances and system trips.

• Increased 12 kW Output (3 Phases): Ample capacity for the simultaneous operation of heavy equipment: three-phase air conditioners, electric boilers, ventilation systems, or charging two electric vehicles.

• High-Voltage (HV) System: Operates with high-voltage battery storage packs, which guarantees ultra-fast charging (essential during frequent blackouts) and minimizes energy conversion losses.

• Instant Backup Power (EPS): Seamless and unnoticeable for domestic appliances transition to battery power during unexpected utility grid failures.

• Powerful Solar Array Support: 2 independent MPPT trackers allow for the connection of a solar array with a total capacity of up to 18 kW, ensuring excellent generation even on cloudy days.

• Advanced FoxCloud Monitoring: Complete control over each phase, solar generation, and consumption profiles right inside your smartphone (Wi-Fi module included).

Ideal For:

• Large cottages and country houses featuring a three-phase grid connection and significant electricity consumption.

• Commercial properties (restaurants, auto repair shops, small manufacturing sites, offices) that require uninterrupted power for three-phase equipment.

• Homeowners operating solar stations under the "Green Tariff" (Feed-in Tariff) who want to maximize profit from exporting electricity.

• Users who value reliability, silent operation (IP65 protection), and modern product design.

Explanation of Terms:

• Unbalanced Phase Load – A vital feature for three-phase hybrid systems. It allows the inverter to output different power levels across different phases. For example, if a washing machine (2 kW) runs on Phase 1, while only a TV and lightbulbs are active on the others, the inverter balances exactly that 2 kW load without errors or overloading.

• Three-Phase System (3-Phase) – A power grid connection with a voltage of 380/400V, required to run specific high-capacity equipment.

• High-Voltage (HV) Battery – An energy storage system operating at higher voltages, meaning the inverter generates less heat, cables can be thinner, and the overall efficiency of the station is significantly boosted.
