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. Choosing the right inverter and PV combiner box is essential to ensure your solar system performs efficiently and safely. A string is a series of solar panels connected in sequence. The combiner box collects power from each string and sends it to the inverter for safe and organized operation. The combiner box collects those string outputs, provides protection and switching functions, and. A PV combiner box is an electrical distribution device used in utility-scale solar systems to combine multiple DC inputs from solar panel strings into a single output circuit.
