Product description
HT Series DC+AC Solar Combiner Box 600V IP65 with Surge Protection & Breakers
Overview
The HT Series DC+AC Solar Combiner Box is a unique integrated solution that combines both DC and AC protection in a single IP65‑rated enclosure. Designed for photovoltaic systems that require string aggregation and grid interconnection, it features a complete DC circuit (600V) and a dedicated AC circuit (385V) with separate surge protection and breakers.
This all-in-one design simplifies installation, saves space, and ensures reliable protection for both the DC side (panels to inverter) and the AC side (inverter to grid). Certified with CE, it meets stringent safety standards and is built for outdoor installation in residential, commercial, and industrial solar projects.

Frequently Asked Questions
Q： Can this combiner box be used for both DC and AC circuits from the inverter to the grid？
A： Yes, it is designed to combine one DC string (from PV panels) and one AC output (from inverter to grid) in one enclosure, with separate surge protection and breakers for each circuit.
Q： Is the enclosure suitable for outdoor mounting？
A： Yes, the IP65 rating makes it dust‑tight and protected against water jets, suitable for direct outdoor installation.
Q： Do you offer other configurations (more strings, different voltages)？
A： Yes, we can customize the DC/AC configuration to meet your project requirements. Please contact us for details.
Q： What is the advantage of using a combined DC+AC combiner box？
A： It simplifies installation, reduces the number of separate enclosures, and centralizes both DC and AC protection, making maintenance easier and saving space.
