SOLAR VENSYS SOLAR TECHNOLOGY The smart VENSYS String Combiner 1 SOLAR www.vensys-elektrotechnik.de VENSYS Quality >Made in Germany< Our reliable and trustworthy systems minimise the risk and increase the benefits for customers and partners thanks to a 100 percent commitment research, development, safety and quality standards. Safety and quality deserve top priority. Hence, only technologies from carefully selected suppliers are used in all our products. Each of our products has passed extensive testing in our own laboratory facilities to meet our high safety and quality standards. 2/5 SOLAR www.vensys-elektrotechnik.de VENSYS SOLAR TECHNOLOGY STRING COMBINER Off-Grid Systems VENSYS-Quality guarantees reliability Hybrid Systems On-Grid Commercial / Industrial Systems HIGHLIGHTS • Safe and efficient collection of up to 16 strings • Compact and robust housing for indoor and outdoor applications • Easy installation thanks to an optimised design and low weight • Innovative monitoring system • Excellent safety standard thanks to protective features and optimal monitoring • Operation at ambient temperatures from -20 °C to 45 °C DESIGN PV modules must be connected parallel to the central inverter; The powerful and compact String Combiner of VENSYS Electronics GmbH serves this purpose. Whether indoors or outdoors, thanks to their efficient and robust design the boxes are easily installed stand for durability and maximum safety in the PV field. The innovative monitoring system enables an optimal management of each solar module individually, thus achieving maximum output from your solar park. Power and connection The VENSYS String Combiner offers 16 string inputs that are connected in pairs and can be operated with up to 150A as well as 1000V. All inputs are equipped with PV fuses (all poles) and are brought together on a load-break switch. The sealing range measures 22 to 36 millimeters, and cable cross sections between 70 and 2 x 240 mm² are compatible. Robust and compact The robust housing ensures the protection against foreign matter and bad weather conditions with safety class IP55 or optionally IP65, at an operating temperature between -20 °C and +45 °C. In addition, the simple design and low weight allow for quick and easy installation and maintenance. Control and safety The innovative monitoring software safeguards that each module in the PV-field is monitored and analyzed precisely. Occurring errors in the strings are thus detected at an early stage, the corresponding string combiner is disconnected automatically from the inverter, while the rest of the system continues to operate and generate a valuable yield. A remarkably fast service is guaranteed through this accurate localization of errors. Therefore, downtimes are minimised, and a higher output can be generated. The collected operating data are transmitted to superordinate controllers for monitoring and analysis purposes. This transfer is carried out either through copper or fiber-optic technology. 3/5 SOLAR www.vensys-elektrotechnik.de TECHNICAL DATA VENSYS STRING COMBINER GENERAL 1. Version 2. 3. 4. 5. 6. 7.
