B-2 Energy Meters & Solar Radiation Sensor
This example shows the configuration jumper settings and sensors for a typical Solar PV metering
installation, which monitors 2 energy meters (eg generation and export) and solar radiation.
The energy meters (electrical or heat) must be configured to provide a pulse output (dry contact, KYZ or
open-collector) of typically 1000 pulses per kWh depending on system size.
Sensors:
•
Port D1 = Pulse output from generation energy meter (dry contact or open-collector)
•
Port D2 = Linked to port D1
•
Port D3 = Pulse output from export energy meter (dry contact or open-collector)
•
Port D4 = Linked to port D3
•
Port D7 = Solar Radiation sensor (Pyranometer)
As the digital ports A1-A4 are not used, they are configured in dry contact mode. Similarly the analogue
ports D8, D9 are not used, so they are configured as 0-5VDC mode.
