HT 2 String 2 Output 1000V Solar Combiner Box IP65 – Dual Isolator & Surge Protection | CYF Energy

HT Series 2 In 2 Out 1000V Solar PV Combiner Box IP65 – Dual Isolator & Surge Protection

Overview

The HT Series 2‑Input 2‑Output Solar Combiner Box (Model HT18WAY) is designed for high‑voltage PV systems that require independent control and safe manual disconnection of two separate DC circuits. Each of the two inputs is routed to its own output, equipped with a 1000V DC isolator (for safe manual switching), a 2P 1000V surge protection device (SPD), and individual DC fuses.

Housed in an IP65‑rated waterproof enclosure, this combiner box is built for outdoor use. All components are CE certified, ensuring compliance with European safety standards.

  Frequently Asked Questions

  Q： What is the difference between an isolator and a breaker？
  A： An isolator is designed for manual disconnection during maintenance and does not provide automatic overcurrent protection (fuses handle overcurrent). A breaker provides both manual switching and automatic trip on overcurrent. This model uses isolators + fuses.

  Q： Can I use this combiner box for 1500V systems？
  A： No, this model is rated for 1000V. For 1500V, please check our 1500V series.

  Q： Is the enclosure suitable for outdoor use？
  A： Yes, the IP65 rating makes it dust‑tight and protected against low‑pressure water jets, perfect for outdoor installation.

  Q： Do you offer models with breakers instead of isolators？
  A： Yes, we have models with DC breakers. Please contact us with your specific requirements.
