Specifications of photovoltaic panel jumper wires

Solar jumper wire works similarly to jumper cables for cars, transferring electricity from one solar panel to another. These short lengths of PV wire have MC4 (or site-specific) connectors on both ends and connect solar panels together along a row.

Jumper cables are used to join the Canadian Solar module connector T4 to other type of connectors (H4 or MC4) in the PV system. The jumper cables have different connectors in each end (male + female) to convert to different connector types, and the length is 300 mm. Typically, one pair of jumper cables are needed for every string of modules.

Learning the basics of solar panel wiring is one of the most important tools in your repertoire of skills for safety and practical reasons, after all, residential PV installations feature voltages of up to 600V. There are three wiring types for PV modules: series, parallel, and series-parallel.

One of the most comprehensive sets are the IEC standards. IEC 62548 sets out design requirements for PV arrays, including DC array wiring, electrical protection devices, switching, and earthing.

Aluminum 2KV Photovoltaic Cable is primarily used for interconnection wiring of grounded and ungrounded photovoltaic power systems. When installed in accordance with NEC article 690.31(C)(2), PV source and PV output circuits, single-conductor cable of all sizes can be installed in outdoor cable trays. The PV cable is for applications up to 2000 .

6 FAQs about [Specifications of photovoltaic panel jumper wires]

What is PV cable / PV wire?

Nearly all PV module manufacturers are using “PV cable/PV wire” fastened to their modules. See 690.35 and 690.31. PV cable or PV wire is that cable meeting UL Standard 4703 for the use on modules and in exposed PV source circuits on ungrounded PV arrays which, in turn, can be connected to the transformerless (non-isolated) PV inverters.

What is aluminum 2kV photovoltaic cable?

How long is a jumper cable?

The jumper cables have different connectors in each end (male and female) to convert to different connector types, and the length is 300 mm (11.8 in). Typically, one pair of jumper cables are needed for every string of modules. TLIAN (CHANGSHU) CO., LTD.

What determines the durability and safety of PV cables & connectors?

The quality of the components used and the care taken in complying with the code determine the durability and ultimate safety of these cables and connectors. PV modules come with connectors attached to the ends of the cables that have been permanently attached to the PV module. See photo 1.

What are jumper cables used for?

Jumper cables are used to join the Canadian Solar module connector T4-PC-1 to other type of connectors (PV2b, MC4 or H4) in the PV system. The jumper cables have different connectors in each end (male and female) to convert to different connector types, and the length is 300 mm (11.8 in).

What type of cable do I need for a solar array?

For rooftop PV installations, you can use the PV wire, known in Europe as TUV PV Wire or EN 50618 solar cable standard. For ground-mounted PV installations requiring underground installations, you need an Underground Service Entrance (USE-2) cable. Are you using microinverters or string inverters for your array?
