Measuring Current Effectively

Power Meters

A power meter relays the measured amount of power to the Solar-Log™ for analysis. If you wish to consume the self-produced power from a PV plant, the meter serves as a consumption meter, displaying a comparison of the power produced and consumed. The meter can be configured to operate with the Solar-Log™ in three different modes:


  1. Measuring power consumption for the optimal utilization of self-produced power.
  2. Measuring the total amount of power that has been fed into the grid.
  3. Measuring the power production from inverters that are not directly supported by Solar-Log™.

Controlling Reactive Power & Recording Measurements

Utility Meter

The Solar-Log™ Utility Meter is a universal metering device. It can be integrated in both low- and medium-voltage networks (via a transformer) and is needed for various tasks. In addition to voltage-dependent reactive power control Q(U), it is also used for reactive power control at the feeding point and to record the data that is needed consumption meter for heavy loads.
