Mains supply to DATCOM components
General Power is supplied to DATCOM components independently of the inverter. This ensures a
power supply when there is no power from the photovoltaic modules. Power is supplied to
DATCOM components via Fronius com cards or plug-in power packs. This is particularly
important when using a Fronius Sensor Card because this ensures that the datalogger will
be able to record all data even at night.
