The smart meter monitors your current usage and transmits it to your charging station

In combination with a KEBA KeContact P30 x-series wallbox, the smart meter makes dynamic load management possible. This allows for optimal use of the grid connection and prevents it from being overloaded. The fewer devices in your house that are consuming power, the more power your electric car receives. Individual household devices can also be monitored with additional current sensors.

Full Transparency

In addition to power consumption, the TQ EM 300-LR smart meter measures real, reactive and apparent power, current and voltage. You can have the data exported and emailed to you or download it from an FTP server. The integrated web server makes it easy to configure data and display it clearly.

Comprehensive Monitoring

In addition, it is possible to monitor individual devices or groups of devices with up to 96 current sensors. Up to 8 sensor bars can be connected to the TQ EM 300-LR. This gives you an even more comprehensive picture of your energy usage.
