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.
This standard requires that the insulation resistance of the PV system shall not be less than Riso = (Vmax_PV / 30 mA). For example, an inverter with a maximum DC input voltage of 1000V should not connect to the mains if the Riso is less than 33.
