skylog® 
Data Logger
System

Our powerful data logging system for PV installations, skylog®, has been designed with robustness and versatility in mind. Communicating with the plant using any of the standard bus technologies (CAN, RS-422, RS-485, Ethernet), skylog® can read and save data from a variety of terminal devices, irrespective of make. On request, an uninterruptable power supply (UPS) can provide power to all other monitoring components supplied by the CAN bus cable, ensuring dependable operation even in the event of a power failure. In locations having unreliable internet connections, local data storage is secured by skylog®’s substantial data buffering capacity. skylog® therefore forms an indispensable component of any monitoring system where dependable operation is key.

Comprehensive Functions

  • Data logger component of a complete monitoring system for photovoltaic power plants
  • Data buffer in case of Internet breakdown, depending on system configuration (string or central inverters): 1 – 4 weeks
  • Basis for long-term energy production verification
  • Uninterrupted power supply for all monitoring components
  • Support of inverters from various manufacturers as listed in the skytron® energy compatibility list
  • Optionally available: grid stability management functions

Monitored Devices

  • Inverter, for example: inverter state, failure state, energy production
  • DC USV: battery charge condition and battery temperature
  • skylog® CP: Special adapter for connecting a reference module
  • skyCONNi, data gateway for the connection of several devices such as: energy meters, temperature sensors, reference cells, pyranometers, analogue sensors and actuators, alarm systems and process control systems (inputs and outputs), modules: module and ambient conditions
