After selecting all of the panels, wires, inverters and any analytic software or batteries or storage, you wouldn’t want to select the wrong combiner box and accidentally undermine the entire setup. Like with any product selection, the project’s type, size and scope mean everything when selecting a combiner box, and what works best for a residential install doesn’t translate to commercial, and so on.

Choosing the right combiner box for the job isn’t difficult, but you have to understand the site, the other components and their relation to the combiner. Keep these questions in mind when specing your next job.

Key questions to answer before making your selection:

• How easy is it to install?

• What functions do you need?

• Have you considered monitoring?

• Does is it protect the system?

• Do you even need a combiner?
