AI Technical Summary
⚠Technical Problem
The installation of solar array DC combiner boxes is time-consuming and prone to component damage due to high voltage or current connections, and conventional designs suffer from thermal coupling between fuses leading to increased failure rates.
⚗Method used
A DC combiner box with pre-installed crimp connectors and an offset arrangement of fuse holders that decouples thermal load, allowing for faster installation by eliminating the need to bend large gauge cables and reducing thermal coupling between fuse rows.
🎯Benefits of technology
Facilitates quicker and safer installation by minimizing cable stress and preventing component damage, while reducing thermal failures through improved heat management.

Abstract
This disclosure describes a DC combiner box that has improved field installation capabilities and has decoupled thermal load between input fuses. The DC combiner box can be a junction box that includes a backplate; an input bus mounted to the backplate; an output bus mounted to the backplate; a crimp connector mounted to the backplate and electrically connected to the output bus; and a housing at least partially enclosing the output bus and the crimp connector.
