Installing the sensors
Mounting the kWh meter in the meter cabinet must be done with care. If the meter is used for solar production, the in- and output must be swapped. Otherwise the meter would run in reverse, but this is blocked by the meter so it would stay at 0.
- Blinking led on existing meter
It is also possible to use an existing meter without S0 pulse but with a blinking LED and mount a phototransistor to the LED.
