STRING MONITORING
pending
Defective pV modules and components – as well as faulty cables or
connectors – can lead to potentially dangerous arc-faults. Undetected,
an arc-fault could result in an electrical fire, causing damage to the
PV installation and surrounding property.
rESYS aFD is a compact solution for integration within a pV combiner box,
designed to detect and interrupt an arc before it results in a major electrical
failure. Fully compliant with NEc 2011 and 2014, rESYS aFD also monitors
the pV energy production at string level to mitigate against energy losses and
guarantee the return on investment of your pV facility.
The solution for
PV Arc-Fault & String Monitoring
AFD and AFCI compliant with UL1699B
•P
V systems installed
on commercial buildings
• PV systems installed
on ground mounted plant
Advantages
Modular Configuration
• Reliable Arc Detection
Based on Socomec’s patented technology
and with immunity to electrical disturbances,
RESYS AFD:
• Basic version (AFD only):
1 basic
Master Board
- prevents nuisance tripping and false alarms,
reducing the cost of service call-outs,
+
- ensures accurate arc-fault detection and
safe interruption.
- As a result, minimal additional testing and
certification is required with new Combiner
Box designs.
• String Monitoring
- RESYS AFD is also available with an
accurate string current monitoring system.
- Data is sent via RS485 using standard
Modbus protocol.
SIRCO PV
• PV load break switch
with tripping function
• Suitable as Interrupting Device
for AFCI function as required by
NEC 2014, article 690.11
• 1000 V 100 A to 800 A
• Monitoring version
(AFD + String level monitoring):
1 monitoring
Master Board
+
• Easy To Integrate
- The compact size of the RESYS AFD means
that it can be integrated even into small
Combiner Boxes.
- Compatible with standard BOS components,
performance is optimized when used
in conjunction with SIRCO PV with trip
functionality.
