EKPBSR AFCI Combiner Box -Arc Fault Protected PV String Solutions
EKPBSR AFCI (Arc Fault Circuit Interrupter) Combiner Box is a state-of-the-art protection device engineered for next-generation commercial and industrial photovoltaic (PV) systems. It addresses the critical safety challenge of DC arc fault detection and prevention, combining robust string combining, early warning, and networked monitoring in a durable enclosure.
Features:
1. Current Combining: It aggregates power from multiple PV string inputs into a single output, simplifying system wiring.
2. Arc Fault Protection: The AFCI technology detects dangerous electrical arc faults within the DC circuitry and interrupts the circuit to prevent potential hazards like fires.
3. System Isolation: It provides a means to isolate parts of the system for maintenance or emergency disconnects.
4. Performance Monitoring: Can real-time monitoring of current, voltage, and fault conditions.
Applications:
Rooftop Solar Systems: Especially where enhanced fire safety is required.
Large-scale PV Installations: To comply with electrical codes and reduce risks associated with high DC voltages.
Why Choose EKPBSR AFCI Combiner Box?
Deploy EKPBSR AFCI combiner boxes to enhance safety, enable code compliance, and add value throughout the project lifecycle—protecting valuable assets and reducing downtime and service risks in large solar arrays.
