Step 2. PowerRouter AC connection
The PowerRouter is a 1-phase inverter that is connected to the utility grid via the ‘AC grid’ connection. Figure
3 is a simplified technical diagram of a self-use system based on the PowerRouter. Although not shown in this
drawing, circuit breakers and a master switch must be installed.
The PV counter, designed as an optional extra for the PowerRouter, registers the amount of energy derived from
the PowerRouter. The amount of energy fed into the grid and the amount used from the grid are measured using
the bi-directional (generation/consumption) meter. These three values enable you to calculate the percentage of
self-use.
