The Fronius Interface Card easy has a serial interface with an open data protocol, that enables following data from one Fronius inverter to be downloaded and processed: current data daily information total data year information (only in combination with a data logger) The Interface Card easy is not a LocalNet-component, therefore it does not require a Com Card and Datalogger. Advantages Integration of system data in other IT systems (building control, alarm systems, etc.) Data transfer to PC for other visualization purposes (e.g. to include PV data on a homepage) Interface to other data logging systems Power is supplied to the Interface Card easy via the AC side of the inverter. This ensures that power is supplied to this component 24 hours a day. The Datalogger easy was created for small systems with only one Fronius IG. It has the same functions as its big brother – Datalogger pro – but is restricted to one inverter. Low-cost and high-power. *The Interface Card easy can be used for Fronius inverters with serial numbers 14330071 and higher following a software update, (excluding 277 volt applications on IG Plus). The software update is not required for serial number 1715xxxx and higher.In the case of an older Fronius IG, a hardware update is required in addition to the software update.
