Fox ESS HP3 Box-E1-WL: The compact 3-phase hydro module

The HP3 Box-E1-WL hydro module is an optimized all-in-one solution for modern heating systems. Thanks to its compact and lightweight design, it saves significant space in the utility room and considerably reduces installation time. It acts as a central interface that combines all critical hydraulic and electrical control components in a single housing.

System advantages & Integration

  • Comprehensive equipment: The module already includes a 9 kW backup heater, a 3-way valve, and an integrated dirt filter.
  • Safety & durability: For reliable operation, a pressure relief valve and a vent valve are installed directly at the factory.
  • Intelligent networking: Thanks to the SG Ready function, the system can be ideally integrated into photovoltaic systems. Monitoring is handled flexibly via Wi-Fi or LAN using the Fox ESS Cloud.
  • Flexible control: Operation is possible via the wired controller, an intuitive app, or the web portal.
