We size the combiner box in nearly the exact same way as the charge controllers. The formula for verifying voltage compatibility is identical: (Panel Voc) x (# Panels in Series) x (Correction Factor from NEC 690. 7*) < max input.
This guide explains how combiner boxes work, how they have evolved, how to select the right model, and what future trends will shape the next generation of solar infrastructure.

By consolidating multiple PV strings into streamlined outputs while integrating advanced DC arc-fault detection and interruption, this modular unit instantly identifies dangerous arc faults and disconnects the circuit before a fire can ignite.
Inside, they contain multiple electrical components such as circuit breakers or fuse holders, busbars for distributing power, and often include monitoring equipment to oversee voltage and current for each string of solar panels.
In this article, we walk you through a real-world case—144 solar panels of 555W each paired with a powerful 80kW inverter—and demonstrate exactly how to calculate your system's configuration. You'll learn how to match string configurations, assign MPPTs, and size your combiner box .
