More self-consumption of solar power
A small box with a lot of smarts: Dafi’s Smartfox Pro

The energy management system has been continuously developed since 2012 – now the fourth generation is on the market. If there is too much solar output, an analogue outlet is used to variably activate a heating element via a power controller and thereby to heat water. The Smartfox Pro is equipped with four relay outlets and can control additional consumers such as a Smart Grid heat pump or air conditioners.

To charge an electric vehicle, the Smartfox charging station is operated in single-phase mode at 1.3 kilowatts. If there is a surplus of more than 4.3 kilowatts, the charging station switches to three-phase mode. It is possible to choose between surplus charging and forced charging. A universal RS485 interface is also available. The EMS is mounted to the DIN rail in the distribution cabinet and connected to the Internet router via LAN. (mfo)
