Photovoltaic Solar Panel Connectors – Dependable PV Connectivity from elmex

With the drive for greener energy the utilisation of solar power is a popular choice, from the large-scale solar farms you can see dotted around the countryside to small scale solar panel installations fitted to the roof of a house. All these systems require a reliable and secure method of connector technology to ensure the power they create is safely transferred to where it should be.

Where reliability and compatibility matters elmex Photovoltaic (PV) Connectors are a dependable solution, offering a large array of designs to suit a wide variety of applications. Here, we take a quick look at just a small selection of some of the solar panel connectivity solutions manufactured by elmex and available to purchase from Kempston Controls today.

Photovoltaic Connectors

Photovoltaic Straight Connectors

The elmex PV (Photovoltaic) Solar Straight Connectors, with NEC interlock, have been designed for applications in PV power generation systems, featuring a male plug and female socket design and are constructed from a UV resistant flame retardant thermoplastic. These solar panel connectors incorporate a flexible water-tight sealing (providing IP68 protection) and come in male and female connector versions to minimise the chance of incorrect connections.

These hardwearing PV straight connectors are certified for PV solar cables 2.5, 4.0, 6.0 mm² diameter. The cables used should be TUV certified as per standard 2Pfg 1169/EN 50618 to ensure a proper connection.

DBL Power Distribution Blocks

DBL Power Distribution Blocks – compact space-saving versatility from Entrelec

Entrelec DBL Power Distribution Blocks offer a compact space saving and modular design with 3 configuration options. The clever design is easy to install via either DIN rail or panel mounting and provides greater flexibility in the field with 3 configurations in 1 product, a single pole splitter, a multi-pole splitter and finally, a grouping option. This concept reduces assembly time by up to 80% when compared to traditional systems, and to simplify panel mounting, installation information is engraved on the foot of each distribution block.

Combined Distribution

When used as a single-pole splitter, this facility simply splits the mains power input into several individual outputs. The multi-pole splitter is facilitated by an interlocking function making it easy to combine the distribution blocks, and the grouping configuration allows the grouping of several inputs into 1 output. Flexible in use, these power distribution blocks include a two-direction opening – reversible cover that helps facilitate easy identification and wiring, with all the technical data and specifications easily visible on its surface.

DBL boxes are ideal for distributing power in numerous industrial and commercial applications, with certain models (DBL250-F and DBL500-F) having the facility to be used with flat conductor systems. The modular, touch proof and rugged design, with an IP20 rating, eliminates the need for bus bars, isolators, fasteners and protection screens.

Wide Range of Applications

Typical applications include – distributing power in industrial and commercial electrical panels, heating, ventilation, and air conditioning (HVAC), power distribution units, combining photovoltaic (PV) strings in one output, PV combiner boxes and central inverters in solar power plants and more.
