The following examples illustrate typical Single-Line Diagrams (SLDs) for a range of Solar PV system configurations, including: a simple PV string inverter (with and without power optimisers), systems with multiple MPPT inputs, DC combiner boxes with multiple strings, setups featuring array and sub-array separation, and a utility-scale PV system layout. These diagrams help visualise practical design approaches and integration methods within ElectricalOM. For a detailed walkthrough, users are encouraged to watch the ElectricalOM Webinar – Solar PV Design Based on BS 7671 Section 712, available on YouTube [Click Here].
