Service & Design
The BLA® (Big Lead Assembly) takes all the complexity out of wiring your solar field. Using Shoals™ latest in-line fuse and wire manufacturing technology, we offer you a site free of traditional DC string combiners.
Simplify your system
The BLA is an aboveground aluminum trunk system that combines the functionality of cable assemblies, combiner boxes, and fusing all into one. This free air de-rated system eliminates the need for standard combiner boxes, messy multiple conductor string wires, cable trays, trenching, and field crimping.

Shoals’ patented Interconnect System and home run harnesses reduce the specialized labor required in your installation, making the integration of solar panels a breeze. Shoals home-run harnesses and Interconnect System are perfect for any PV project.
Reduce Labor Costs
Maximize the current rating of the DC combiner fuse holders and reduce the number of DC combiner boxes on site by using a harness that incorporates an inline fuse, installers can pre-combine strings before the combiner box. Configurations are available for bi-facial and crystalline panels, as well as Series 4 & Series 6.

A method of connecting a terminal to a connector. A typical use would be from a combiner box to a string of panels.
A method of connecting two components with connectors. A typical use would be connecting strings between two rows or connecting a string to a Shoals combiner box with pre-installed pigtails.
A method of combining multiple wires without the need for in-field splice. This patented device helps increase efficiency on site while reducing the amount of wire and number of combiner boxes needed.
The next evolution of combiner boxes, optimizing both cost and layout
without sacrificing quality or performance.
Quality Performance
The Shoals High Current Combiner series is used to combine multiple strings per circuit up to a 60A fuse size. This means a more than 50% reduction in return cables over a traditional combiner box. Lab-proven under full load during static heating sequence testing with fuses installed, the High Current Combiner is designed for maximum durability and years of uninterrupted, real-world service. Field installation time has been slashed, space for cable terminations generously increased, and O&M torque points reduced by up to 41%.
