Skylog Datasheet- Brochure

Our powerful data logging system for utility-scale PV installations, skylog®, has been designed with robustness and versatility in mind. Communicating with the plant using any of the standard bus technol-ogies (CAN, RS422, RS485, Ethernet), skylog® can read and save data from a variety of terminal devices, irrespective of make. Its integrated uninterruptable power supply (UPS) provides power to all other moni-DATASHEETskylog®Data Logger Systemskytron® energy GmbH / Ernst-Augustin-Str. 12 / D-12489 Berlinphone: +49 (0)30 688 31 59-0 / fax: +49 (0)30 688 31 59-99info@skytron-energy.com / www.skytron-energy.com© skytron® energy 2014 / Subject to technical change. / 140210PRODUCT FEATURES> Data logger component of a complete monitoring system for utility-scale 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 listskylog® toring components supplied by the CAN bus cable, ensuring dependa-ble 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 depend-able operation is key.MONITORED DEVICES> Inverters, for example:• inverter state, failure state, energy production> DC UPS• battery charge condition and battery temperature> ArrayGuard®• bipolar currents, system voltage, status of overvoltage protector, status of DC main switch> skyCONNi, data gateway for the connection of several devices such as:• inverters• energy meters• temperature sensors• reference cells• pyranometers• analog sensors and actuators• alarm systems and process control systems(inputs and outputs) Powder-coated steel cabinet with mounting framesskytron® energy GmbH / Ernst-Augustin-Str. 12 / D-12489 Berlinphone: +49 (0)30 688 31 59-0 / fax: +49 (0)30 688 31 59-99info@skytron-energy.com / www.skytron-energy.com© skytron® energy 2014 / Subject to technical change. / 140210TECHNICAL DATAHARDWARE1 DC UPS 24 V DC2 Batteries AGM 12 V, 40 Ah1 Industry PC Flash Card up to 1 GB, battery-backed clock1 Ethernet switch fibre-optic networking2 Temperature sensors to read temperatures in inverter station and battery cabinetSOFTWARESystem Software LinuxAccess Internet Browser, Java V1.6DATA TRANSFEREthernet, FOC 1x 10/100BaseTEthernet, copper max. 5CAN 2x 2.0BRS422 max. 4x (optional)RS485 max. 4x (optional)OTHER INTERFACESDigital outputs max. 4x break and make contacts (optional)Digital switch inputs max. 8x to monitor potential-free contactsCurrent inputs max. 4x 4-20 mA (optional)Energy meter 1x RS485 (HD) (optional)Internal Plant CommunicationProtocol IP Ethernet, skytron® specific communicationData rate 10/100 MBit/sConnectionmultimode 50/125 µm, e.g. HITRONIC® HQN outdoor cable with SC connector 4G50/125 multimode up to 4 km / 2.5 milesoptional: single mode 9/125 µm, e.g. HITRONIC® HQN outdoor cable with SC connector 4E9/125 single mode up to 20 km / 12.5 milesSensor Systems (2 x CAN Bus)Protocol CANopen as to CiA standard DS-301Data rate 20 kBit/sRecommended cable Li2YCYv 8x2x0.5 (TP) or equivalentNumber of users per CAN Bus max. 27ELECTRICAL DATAPower supply195-265 V AC/47-63 Hz mainsUL version: 110 to 230 V AC / 2.5 to 1.2 A AC / 44 to 66 Hz mainsPower supply for field sensors 24 V DC over DC-UPSBackup system 24 V DC, 2 batteries AGM 12 V, 40 hOvervoltage protector 230 V AC, 24 V DC and CAN BusMECHANICAL DATA SWITCH CABINET BATTERIES BATTERY CABINETProtection class IP 66 / Nema 4,4x IP 10 / Nema 1 IP 54UL listing / Marks cETLus / CE UL / CE pending / CECoastal installations1)Severity level 1 according to DIN EN 60068-2-52:1996Standards UL 60950-1, CSA C22.2 No. 60950-1, EN 60950-1, EN 61000-6Dimensions h x w x dOutdoor cabinet including batteries (option)700 x 500 x 250 mm / 27.6 x 19.67 x 9.84 in1000 x 1000 x 320 mm / 39.4 x 39.4 x 12.6 in175 x 166 x 350 mm / 6.90 x 6.53 x 13.78 in each 380 x 380 x 250 mm / 15.0 x 15.0 x 9.84 inWeight 27 kg; 30 kg with package 59.524 lb; 66.138 lb with package13.6 to 20 kg / 28.66 to 44.10 lb each,depending on type6.7 kg / 14.8 lbMaterial of cabinet powder-coated steel, mounting frames powder-coated steel, lateral ventilation slots, mounting framesAMBIENT CONDITIONS SWITCH CABINET BATTERIES BATTERY CABINETOperating temperature -20 °C to +50 °C / -4 °F to 122 °F -15 °C to 50 °C / 5 °F to 122 °F -15 °C to 50 °C / 5 °F to 122 °FStorage temperature -20 °C to +50 °C / -4 °F to 158 °F -15 °C to 40 °C / 5 °F to 104 °F -15 °C to 40 °C / 5 °F to 104 °FRelative air humidity up to 95 % non-condensing up to 85 % non-condensingskylog®Data Logger System1) Only valid for the outdoor version of the data logger, skylog OD.
