In a parallel setup, multiple inverters share the same power input and work together to make more current at the same voltage.

Once you link two 100W solar panels in series, the voltage increases and the current remains the same.

A single inverter is usually enough to handle the power from all your solar panels. This is often referred to as a string inverter configuration, where multiple panels are connected in series, forming a “string. ”.

This guide gives you the diagrams for each configuration, the decision matrix, the wire gauge chart, and the step-by-step for connecting 2, 3, or 4 panels. I wired my own 6 kW grid-tie array in 2024 — 14 panels in two series strings of 7, feeding a dual-MPPT inverter.
