Best answer


PV connectors are alsoused to form the DC home-run to the inverter. In systems using DC optimizers or microinverters, PV connectors are used to connect the module to the module-level device. To maintain code compliance it is imperative that PV connectors are UL rated for interminability.

  • How are PV modules connected?

  • In large PV plants first, the modules are connected in series known as 鈥淧V module string鈥?to obtain the required voltage level. Then many such strings are connected in parallel to obtain the required current level for the system. The following figures shows the connection of modules in series and parallel.

  • What is the make and model of my PV connector?

  • PV connectors make and model is commonly listed on module data sheets. If you see 鈥淢C4 compatible鈥?then you are most likely dealing with a generic connector. Contact your CED Greentech account manager for confirmation.

  • What are the components of a grid-connected PV system?

  • A general system diagram of grid-connected PV systems is shown in Fig. 6.6 and consists of three main components: PV panels (or arrays), power converters (PV inverters), and ac grid.
