Common Questions

Frequently asked questions featured across the site.

View All FAQs
How does an IPC trunk bus system replace combiner boxes?

Instead of routing individual string cables to a central combiner box, IPCs connect strings directly to a trunk bus cable that runs along the array. This eliminates combiner box hardware, reduces underground conduit runs, lowers voltage drop, and cuts total connection points dramatically — resulting in less labor, less material, and fewer potential failure points.

Why UL 9703 instead of UL 486?

UL 9703 was developed specifically for wiring harnesses in distributed generation systems. It requires more aggressive testing — including freeze cycles, thermal chamber, wet high-pot, and impact tests — than UL 486, which covers a broader range of general-purpose connectors. It’s the highest standard available for solar EBOS connections.

What sizes do your IPCs support?

Our IPC product line covers trunk bus sizes from 1/0 AWG through 1000 KcMil, with tap cable support from #10 AWG up. Available in dual-tap and multi-tap configurations to match your array string count and inverter layout.

What is an insulation piercing connector?

An IPC connects string-level DC wiring to a trunk bus cable by piercing through the cable insulation with tinned copper teeth. This eliminates wire stripping in the field, reduces connection time, and creates a sealed, weather-resistant joint. The result is fewer failure points and faster array commissioning.
