Description
Product information
The solar extension cable set (8 metres, 6mm²) is the ideal solution for moderate distances within a photovoltaic installation where maximum efficiency and future-proofing are paramount. If you need to bridge gaps between your solar modules or want to connect to an inverter or charge controller, this generous 6mm² cross-section ensures that not a single watt of power is lost, even during peak currents.
The set includes two high-quality, double-insulated solar cables: a red cable for the positive terminal (+) and a black cable for the negative terminal (-). Both ends are professionally pre-assembled with MC4-compatible plugs and sockets. Thanks to the 8-metre length and solid 6mm² cross-section, this set is technically perfectly dimensioned for almost all common PV applications (balcony power plants, stand-alone systems, roof systems).
Highlights at a glance
- Maximum efficiency: The 6mm² cross-section minimises electrical resistance to an absolute minimum, which is particularly advantageous for high currents (e.g. modern 400W+ modules).
- Plug & Play installation: The cables come pre-assembled on both sides with MC4-compatible connectors, so no special crimping tool is required.
- Secure identification: The clear colour coding in red (+) and black (-) effectively prevents incorrect polarity along the entire connection length.
- Weatherproof & durable: The special jacket made of cross-linked polyolefin is UV-resistant, ozone-resistant and withstands extreme temperatures from -40°C to +90°C.
- Protection rating IP67: The connectors are completely dustproof and protected against splash water and rain when plugged in.
- High-quality conductor: Tinned electrolytic copper ensures excellent corrosion resistance and consistently high conductivity.
Areas of application
This 8-metre extension is designed for a wide range of application scenarios:
- Balcony power plants
- Perfect to bridge the distance between the solar modules and the inverter if this is mounted offset on the railing, wall or indoors.
- String cabling
- Bridging gaps between module fields on pitched roofs, carports or flat roof structures.
- Motorhomes & camping
- Connecting the solar modules to the charge controller, so you can park the vehicle flexibly in the shade while the panels are positioned in the sun.
Installation & safety instructions
- Negligible voltage drop
- At a length of 8 metres, the 6mm² cross-section provides extremely stable energy transmission. This makes the cable the ideal choice for perfectionists who want to get the maximum yield from their system.
- Strain relief
- Secure the cables to the mounting frame with UV-resistant cable ties. Avoid mechanical strain on the plug connections to ensure lasting tightness of the MC4 connectors.
- Correct locking
- When connecting, make sure that the MC4 connectors audibly click into place. Only then will the connection be permanently waterproof and safely protected against arcing.

FAQs about the solar extension cable 8m 6mm²
Why should I choose 6mm² instead of 4mm² for 8 metres?
For maximum safety and efficiency. Although 4mm² is often sufficient for 8 metres, 6mm² offers higher mechanical robustness and stays cooler under high loads (many amps). It is a future-proof investment for modern modules with high output currents.
Do the connectors fit modules from all well-known brands?
Yes. These cables use MC4-compatible standard connectors. They fit perfectly mechanically and electrically to the connections of manufacturers such as Trina Solar, Jinko, JA Solar, Longi or Canadian Solar.
Can I leave these cables outdoors?
Yes, that's what they are designed for. The cables are certified to current PV standards. They are resistant to ammonia, ozone and UV radiation and can be used outdoors for decades.

The 2 metre Hoymiles BC05 to Schuko connection cable is the compact and safe solution for directly connecting your microinverter of the Hoymiles HMS series to a nearby socket. This short version avoids unnecessary cable loops and tripping hazards on the balcony or terrace if the feed-in socket is in the immediate vicinity of the inverter.It connects the specific Hoymiles "Field Connector" (BC05) to the domestic mains in accordance with standards. The high-quality rubber cable (H07RN-F 3G1.5) guarantees durability and safety, even with direct sunlight or rain in outdoor areas.Highlights at a glancePerfect fit: Specially assembled for Hoymiles microinverters of the HMS series (e.g. HMS-800W-2T, HMS-1600, HMS-2000) with the typical BC05 connector.Compact length (2 metres): Ideal for installations where the inverter is mounted directly next to the outdoor socket to avoid cable clutter.Easy installation: Connects the inverter directly and without additional adapters via "Plug & Play" to a standard Schuko socket.High-quality rubber cable: The heavy-duty rubber cable of type H07RN-F 3G1.5 mm² is extremely robust, oil-resistant and UV-resistant for long-term outdoor use.High protection rating: The BC05 plug on the inverter side is waterproof (IP68), while the Schuko plug is designed for protected outdoor use (IP44).Secure connection: Professionally machine-crimped contacts ensure minimal transfer resistance and maximum safety for power feed-in up to 16 amps.Areas of ApplicationThe 2-metre version is perfect for short distances:Balcony power systems: When the outdoor socket is installed directly on the balcony wall next to the modules.Wall mounting: For façade systems where the cable is fed directly through a hole to the inside to the socket.Garden shed/garage: For direct connection to an existing splash-proof socket indoors.Installation & Safety InstructionsEngage: Make sure the BC05 plug at the inverter clicks audibly. Only then is the connection watertight and secure.Release: To remove the BC05 plug from the inverter, you need a special release tool (Disconnect Tool). Never pull with force!Extension: Avoid extending this short cable with inferior extension cables or multiple sockets. If the distance is greater, use the 5m or 10m version of this cable.Compatibility: This cable does not fit the older HM series (Betteri BC01 connection). The BC05 plug is flatter and more rectangular.

The older HM series (e.g. HM-600) has a round, wavy Betteri connector (BC01) with screw thread. This cable fits only HMS.Is 2 metres length enough?Please measure the route exactly! Note that the cable on the inverter often does not run straight, but has to be laid in a curve. 2 metres is very short and offers little room for manoeuvre. If in doubt, the 5-metre version is often the more flexible choice.Is the cable suitable for permanent outdoor use?Yes. The H07RN-F cable is specially designed and approved for high mechanical stress and weather effects (rain, snow, UV radiation) in outdoor use.
