Fox ESS Unveils Split-Phase Hybrid Inverter Supporting Both 127 V and 220 V Applications

Smart energy storage, dual voltage compatibility, and high efficiency put the new Fox ESS solution at the forefront of solar innovation in Latin America and the U.S.

By EnergyChannel – August 4, 2025

Fox ESS has just launched a new hybrid inverter from its US Series that redefines flexibility and performance for residential and small commercial solar installations. Designed with split-phase technology, the system supports simultaneous operation of both 127 V and 220 V loads—meeting the common electrical configuration in countries across Latin America and North America.

Though technically a single-phase model, the US Series hybrid inverter delivers adaptability for a wide range of settings—from individual homes to apartments and light commercial projects.

Smart, Hybrid, and Scalable

As a hybrid solution, the inverter integrates solar generation, battery storage, and optimized use of grid electricity. One of its standout features is scalability: each inverter supports up to four high-voltage (HV) battery packs in parallel, offering increased autonomy and energy independence.

The system is built for energy-smart strategies like Time of Use (ToU) and Energy Shifting, storing excess solar energy produced during the day for use during evening peak rates—maximizing savings and efficiency. In the event of a power outage, the inverter switches to backup mode in under 20 milliseconds, ensuring uninterrupted supply to essential loads.

Key Technical Features

• Up to 97.8% conversion efficiency

• 100% PV oversizing capacity

• IP65 protection, suitable for outdoor use

• Remote monitoring via web portal, Wi-Fi, or the FoxCloud 2.0 app (available in Portuguese)

  
  

Fox ESS’s new split-phase inverter not only enhances performance and reliability but also empowers users to manage and store their energy according to real needs—whether in homes, businesses, or multi-unit buildings.
