Nedap PowerRouter PR37S Application Guideline

Step 3: Connecting the sensor
The 1-phase sensor (p/n PRA1SENSE) or the 3-phase sensor (p/n PRA3SENSE) measures the ow of current
to and from the public electricity grid. This enables the PowerRouter to measure the demand from the loads
and detect the amount of power being supplied to the grid. When the battery is not fully charged, priority is
rst given to charging the battery. During the evening and night, when no solar power is being generated, the
power needed for the loads in the home is drawn from the battery. The grid and the loads are connected to the
PowerRouter’s AC GRID connection via a parallel switch.

It is possible to connect a 1-phase sensor to the PowerRouter Solar Inverter (PRxxS) to measure single-phase
consumption. It is also possible to connect a 3-phase sensor to the PowerRouter Solar Inverter.
The 1-phase sensor must be connected to the external line (L) conductor at a point where it is possible to
measure the electricity owing towards the utility grid. The sensor will only work correctly if the arrow on the
sensor is pointing towards the utility grid.
