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.
