4 String PV Combiner Box with Dual Outputs 1000VDC | HD Series with Fuse, SPD & Breaker
(1) 4 string pv combiner box with dual outputs for 1000VDC PV systems.
(2) Integrated 4× DC fuses + Type 2 SPD + DC breaker (MCB) for surge and overcurrent protection.
(3) Outdoor IP65 / IK09 PC enclosure, dual outputs, PG cable glands for 2.5–16 mm² conductors.
HD Series — 4 String PV Combiner Box with Dual Outputs 1000VDC
The HD Series 4 string pv combiner box with dual outputs is designed for medium-scale PV arrays. It accepts four string inputs and provides two independent outputs. Each string is individually protected by a DC fuse, and the system integrates a Type 2 SPD and a DC breaker for surge suppression and circuit isolation.

FAQ
What is a 4 string pv combiner box with dual outputs?
A combiner box that accepts four PV string inputs and provides two protected outputs, integrating fuses, SPD, and a breaker.
Does it include surge protection?
Yes, it includes a Type 2 SPD rated 40 kA.
Is it outdoor rated?
Yes, the polycarbonate housing is IP65 and IK09 rated for outdoor environments.
How does it differ from 4 in 1 out models?
This model provides two outputs, while 4 in 1 out versions combine all strings into a single output.
