Product Features of Solar ARC Fault Protection

Engineered with a stainless steel IP65 rainproof enclosure, this Solar ARC Fault Protection system guarantees continuous direct current monitoring in harsh outdoor environments.

Solar ARC Fault Protection Diagram

Modular Detection: Supports 8 to 32 detection channels, providing independent pv arc fault circuit interrupter tracking and status indication for each connected string.
Rapid Fault Isolation: Utilizes a high-voltage relay mechanism to decisively cut off affected circuits in under 2.5 seconds upon detecting an abnormal arc signature.
Intelligent Alarms: Incorporates integrated audible and visual alarms alongside a manual button silencer for immediate on-site fault identification.
System Integration: Features an RS485 communication port and a reserved normally open relay dry contact output for centralized arc fault protection management.
Operational Reset: Includes both manual and automatic reset functions, performing a comprehensive self-test immediately after startup.

Field Applications for Solar ARC Fault Protection

Integrating the EKPV-AFCI model minimizes fire hazards across specialized commercial DC distribution arrays utilizing dependable Solar ARC Fault Protection.

Grid-Connected Systems: Upgrades existing commercial installations lacking built-in afci arc fault circuit interrupter capabilities.
High-Voltage Combiner Boxes: Integrates directly alongside standard 1500V DC solar junction networks to isolate multi-string fire risks before reaching the inverter.
