The Smartfox power controller is a sophisticated device designed for the efficient control of electrical loads in a three-phase system. With a rated output of 6 kW and a voltage supply of 400 V AC at 50 Hz, this power controller is ideal for integration into modern photovoltaic systems. It enables the use of surplus solar energy to maximise the self-consumption rate. The power controller is compatible with a wide range of devices, including boilers, heat pumps and electric vehicles, providing a flexible solution for energy optimisation. The integrated WLAN interface enables simple commissioning and intelligent monitoring, which increases the efficiency of the entire system. With a self-consumption of only 2 W and a robust heat sink, the Smartfox power controller is suitable for both new and existing systems and provides a reliable solution for modern energy management.
