The operation is done comfortably with the in-built web server via the IP-interface or directly at the device. Measured values are clearly displayed on the display or on the screen. If an in-house electricity generation plant generates more electricity than is currently used, it is often more economical to consume the excess electricity itself. This is always the case when the feed-in tariff is significantly lower than the price paid to the energy supplier for the purchase of electricity and is generally applicable in Germany for newly installed or young plants.
