JLCB-P-03 Series PV Combiner Box

JLCB-P-03 Series PV Combiner Box

The JLCB-P-03 series PV combiner box, available in configurations from 1 to 6 inputs, is designed to provide overcurrent and overvoltage protection, enhancing the safety and reliability of inverters operating in solar power systems with a maximum DC input voltage of 550V or 1000V.

This series is built in strict accordance with the CGC/GF 037:2014 standard, featuring a durable construction with an ABS base and PVC cover, a waterproof rating of IP65, and flame-retardant properties. Each unit undergoes thorough testing for temperature rise, impact resistance, UV resistance, and other performance parameters before delivery.

Custom designs are available to suit specific user requirements.
