Hoymiles HMS AC Trunk Cable: 10 AWG Backbone for Large-Format Modules (2.3m Spacing)

The Hoymiles HMS-2.3M AC Trunk Cable is the essential high-capacity cabling solution for the Hoymiles HMS microinverter series. Featuring a generous 2.3-meter (7.5 ft) connector spacing, this cable is specifically engineered to accommodate today’s wider, high-wattage solar panels where standard 2.0m cables fall short. Built with premium 10 AWG conductors, it ensures maximum power transmission with minimal resistance, supporting branch circuits with higher current requirements.

This plug-and-play system eliminates the need for complex field wiring. Each microinverter simply clicks into a trunk port, creating a secure, UV-resistant, and IP68-rated waterproof connection. Whether you are installing a residential HMS-700 system or a high-power HMS-2000 commercial array, this 10 AWG trunk cable provides the durability and electrical overhead needed for a professional-grade installation.

Key Technical Advantages:

• Engineered for Large Modules: The 2.3m spacing provides the extra slack necessary for seamless installation with modern, wide-format solar panels (400W–670W+).
• 10 AWG Performance: Superior to 12 AWG alternatives, this thicker gauge reduces voltage drop and handles up to 32A (standard) or 40A (max) current, allowing for more microinverters per branch.
• IP68 Waterproof Rating: Fully sealed connectors designed to withstand extreme Canadian winters and summer heat without degradation.
• Time-Saving Plug-and-Play: Reduces rooftop labor by up to 70% compared to traditional conduit and wire-pulling methods.
• Sub-1G Optimized: Designed to work alongside the HMS series’ Sub-1G wireless communication, ensuring no interference with your DTU-Pro-S monitoring signal.

Technical Tip: Always remember to purchase an HMS AC Trunk End Cap for the end of each branch to maintain the IP68 waterproof seal. Unused trunk ports should be covered with an HMS Port Cap.
