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 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.

Photovoltaic Panel Mount Connectors

These PV Solar Panel Connectors, with NEC interlock, are suitable for panel mounting connection in PV power generation applications. Robust, these photovoltaic connectors are constructed from UV resistant flame retardant thermoplastic.

Designed for use in photovoltaic equipment including DC Distribution Blocks, Inverters, String Combiner Boxes, etc. These solar connectors feature a hexagonal nut for fixing and tightening them on to a panel.

A silicon rubber o- ring fits between the panel connector and the wall of the photovoltaic enclosure ensuring protection against the ingress of water & dust. Versatile, these PV panel connectors are compatible with some other brands of PV straight connectors.

Photovoltaic Branch Connectors

PV Solar Branch Connectors have been designed for parallel connection with straight photovoltaic male or female connectors and feature NEC interlocks.

Branch connectors, as the name suggests, have 3 branches, 2 for inputs either male or female and 1 for either male or female output. Constructed from UV resistant flame retardant thermoplastic for applications in PV power generation systems.

When mated, they can be disconnected with an elmex open end spanner. PV branch connectors are compatible with leading international brands of a similar construction.

Photovoltaic Straight Inline Fuse Connectors

elmex PV Solar Straight Inline Fuse Connectors (EMPV4IFC, EMPV4IFCM and EMPV4IFC) are used in photovoltaic string protection applications. These connectors provide the option of either using a straight male or female connector at one end and a cable at the other or using straight connectors at both ends for string protection with a fuse.

Straight inline fuse connectors have a plug and socket design suitable for 2.5, 4.0, 6.0 mm² size cables and are made from UV resistant flame retardant thermoplastic. Ideal for use in PV power generation systems, they use a gPV(cylindrical) fuse of ø 10 x 38 mm.

Photovoltaic Branch Inline Fuse Connectors – 1000V

The elmex PV Solar Branch Inline Fuse Connectors (EBWFPVM and EBWFPVF) are utilised for photovoltaic string protection. Branch inline fuse connectors have 3 branches, 2 for inputs either male or female and 1 for output either male or female, with NEC interlocks.

These connectors have a plug and socket design and are constructed using UV & flame retardant thermoplastic and are used in PV power generation system.  PV branch inline fuse connectors are suitable for use with a gPV (Cylindrical) fuse of ø 10 X 38 mm.
