Fox ESS HP3 Box-E-WL: The ultimate all-in-one hydrobox

The HP3 Box-E-WL is the powerful, three-phase system control center of the Fox ESS Hydrobox series. It combines high-efficiency hydraulic components, intelligent control, and safety technology into one standardized cabinet housing. By fully integrating a buffer tank, expansion vessels, and an electric heater, installation complexity is minimized and operational safety is maximized.

Comprehensive system integration

Hydraulic center: Integrates a direct heating circuit, a heating mixing circuit, and a dedicated domestic hot water circuit.
Safety package: Factory-equipped with a dirt filter, safety valve, and a convenient filling port.
Intelligent monitoring: Full control via a touch display (wired controller), app, or web portal thanks to integrated WiFi and LAN.
Smart Home Ready: Native support for the SG Ready function to optimize self-consumption in combination with PV systems.
