For a typical solar module (approx. 10-13 amperes), the voltage drop over 10 metres (run and return = 20m cable length) is very low (usually under 1-2%). An upgrade to 6mm² is only necessary for very high currents (e.g. parallel connection of multiple modules before the cable) or even greater lengths.Can I shorten the cable if 10 metres is too long?Yes, but with effort. You can cut the cable, but you will then lose the cast/crimped connectors on one side. You will then need a special crimping tool for solar cables and new MC4 connectors to reattach. Simple screw connectors or soldering is not recommended for outdoor high-current solar applications.Can I bury the cable directly in the ground?No, better not without protection. Although the insulation is very robust, standard solar cables are not specified for permanent underground installation (risk from stones, moisture, rodents). For laying through the garden, use a low-cost PE conduit or a flexible cable protection hose.

With this solar extension cable set (12 metres, 4mm²) you can also safely and weatherproof bridge larger distances between your solar modules and the inverter or charge controller. The length of 12 metres offers you maximum flexibility, for example to optimally align modules to the sun on a garden shed, garage or far away in the garden, while the technology remains protected in the house.The set includes two double-insulated solar cables (1x red for plus, 1x black for minus), already assembled with MC4-compatible plugs and sockets. Despite the considerable length, the high-quality conductor cross-section of 4mm² made of tinned copper ensures reliable power transmission. The sheathing is specially designed for permanent outdoor use and withstands UV radiation, heat, cold and moisture for many years.Highlights at a glanceExtra range: 12 metres of cable length enable flexible installations even in difficult structural conditions or long routes through the garden.Ready for immediate use: Pre-assembled on both sides with standard MC4-compatible connectors (Plug & Play) – no crimping required.Safety colour code: The set of red (+) and black (-) virtually excludes confusion when connecting and protects your expensive electronics.High-quality material: Tinned copper (4mm²) provides good corrosion protection and low line losses.Weatherproof (IP67): The connectors are dust-tight and waterproof when plugged in, ideal for rain and snow.Durable: The special insulation is resistant to UV radiation, ozone, acids and alkalis and is temperature-resistant from -40°C to +90°C.Areas of applicationThe 12 metre extension solves installation problems for long distances:Garden shed & garage: If the modules are on the outbuilding but the inverter or storage is accommodated in the main house.Shading optimisation: Allows the placement of the modules far from shade-providing trees or buildings.Façade installation: For neat routing of the cables from the façade to the plant room or cellar.String extension: To electrically connect module fields that are structurally separated (e.g. on two different sides of a roof).Installation & safety instructionsNote voltage drop: With 12 metres (24m current path there and back), a physically caused resistance arises. For standard modules (up to around 10–15A), 4mm² is perfectly sufficient. However, if you are planning high-performance strings with very high currents (>20A), you should check the voltage drop.Strain relief: Due to the weight of 12m cable, the connectors on the module should not be under tension. Fix the cable to the frame with cable ties.Mechanical protection: With this length, the cable often runs over edges or through the garden. Be sure to use protective conduit (duct) at abrasive points or for underground installation.Connection: Firmly press the connectors together until a clear "click" is heard. A loose connection can get hot. Properties Product nameSolar extension cable set (12 m) Cable length**12.0 metres** (per cable) Cable cross-section**4.0 mm²** Rated voltage**1500 V DC** Max. operating currentup to **30 A** (depending on environment) Plug type**MC4-compatible** Conductor materialCopper (fine stranded, tinned) Protection type**IP68** (dust and waterproof) Operating temperature**-40°C to +90°C** Colour1x red (+), 1x black (-)  FAQs about the solar extension cable 12mIs the power loss already too high at 12 metres?No, not for typical applications. With a typical balcony system or a string with e.g. 10 amps, the voltage drop at 12 metres (4mm²) is about 1.5 to 2 volts. This corresponds to a loss of around 1-2%, which is absolutely within the acceptable range. Only in extreme low-light or very high current situations would a 6mm² cable be more advantageous.Can I also install the cable indoors?Yes, absolutely. The cables are designed for rugged outdoor use (UV/weather), but can also be safely used indoors, in cable ducts, or behind drywall. They are halogen-free and flame-retardant.Do the connectors fit every inverter?Usually, yes. Almost all modern PV modules and microinverters (e.g. Hoymiles, Deye, NEP) use the MC4 standard (or compatible types such as TS4). The connections on this cable are mechanically and electrically suitable for them.

With this solar extension cable set (15 metres, 4mm²) you can also master extensive installations and difficult cable routes. A length of 15 metres gives you enormous freedom: you can place your solar modules where the sunlight is highest (e.g. at the end of the garden or on an outbuilding), while the inverter or battery is safely and securely housed in the house or cellar.The set consists of two high-quality, double-insulated PV cables (1x red for plus, 1x black for minus). Both cables are already professionally pre-assembled with MC4-compatible plugs and sockets ("Plug & Play"), so you do not need any special tools. The conductor made of tinned copper guarantees good conductivity and corrosion resistance even over this long distance.Highlights at a glanceMaximum flexibility: 15 metres in length bridge large distances between the generator field (modules) and the technical room.Plug & Play: Ready for immediate use thanks to pre-assembled MC4-compatible plug connectors (male/female).Fault protection: The colour set consisting of Red (+) and Black (-) ensures clear assignment of the poles and prevents dangerous polarity reversal.Weatherproof & robust: The special insulation made of cross-linked polyolefin is extremely UV-resistant, ozone-resistant and withstands temperatures from -40°C to +90°C.Protection class IP67: The connections are dustproof and waterproof in the plugged state (short immersion).Certified quality: Meets common standards (e.g. EN 50618) for voltages up to 1500V DC.Areas of applicationThe 15-metre extension is ideal for installations with large distances:Ground-mounted systems in the garden: When the modules have to be positioned far away from the house to avoid shading.Outbuildings: Connecting modules on garage, carport or shed to the main house.Complex cable routing: When cables have to be laid around many corners, through empty conduits or shafts and direct routing is not possible.Façade systems: For routing the DC cables from high façade positions to the cellar.Installation & safety instructionsConsider cable losses: With 15 metres of cable length (30m circuit in total), a physical resistance occurs. For typical PV applications (high voltages with strings or micro-inverters), 4mm² is fine. However, for pure 12V stand-alone systems (charging a battery), the voltage drop would be too high – thicker cables or shorter distances are recommended here.Do not wind up cables: Avoid winding excess cable into coils (coil effect/heat build-up). Lay it in loops instead.Use protective conduit: When laying in soil or in areas with risk of rodents (attic/garden), a protective conduit (empty/ corrugated conduit) is strictly recommended.Strain relief: The high own weight of 15m cable must not be pulled on the small connectors of the solar module. Fix the first section of cable firmly to the module frame. Properties Product nameSolar extension cable set (15 m) Cable length**15.0 metres** (per cable) Cable cross-section**4.0 mm²** Cable type**H1Z2Z2-K** (PV cable) Rated voltage**1500 V DC** Conductor materialElectrolytic copper, tinned (Class 5) Plug connections**MC4-compatible** (crimped) Protection rating**IP68** (plugged) Temperature range-40°C to +90°C CertificatesTÜV Rheinland / CE / EN 50618 FAQs about the solar extension cable 15mIs a 4mm² cable still efficient at 15 metres?For grid-connected systems: Yes. If you use the cables for a balcony power system or a roof system (voltage approx. 30-40V or higher), the loss is acceptable (approx. 2-3%). For 12V stand-alone systems: No. If you want to connect a 12V module directly to a battery, the voltage drop at 15m is too high. In this case, use a 6mm² or even better 10mm² cable.Are the cables suitable for direct burial?No. The cables are extremely weather-resistant ("underground cable-like"), but are not protected against mechanical damage (stones, spade cut, animal bites). Outdoors on the ground, you should always use a cheap PE pipe or flexible conduit as a protective sheath.Do the connectors fit my balcony power system?Yes. The MC4 standard (and compatible types) is used by almost all module manufacturers and micro-inverters (Hoymiles, Deye, NEP etc.). The connectors fit together mechanically.

With this solar extension cable set (20 metres, 4mm²) you can bridge enormous distances between your solar modules and the technology. This length is ideal when you need to place your panels in a sunny spot in the garden, on a distant garage or an outbuilding, while the inverter or storage system is installed centrally in the house.The set consists of two double-insulated PV cables (1x red for plus, 1x black for minus). Both ends are already professionally fitted with MC4-compatible plugs and sockets ("Plug & Play"). The conductor made of tinned copper ensures durability; with this long length, the physical voltage drop should be taken into account (see notes). The cables are designed for permanent outdoor use in all weather conditions.Highlights at a glanceEnormous range: 20 metres in length gives you maximum freedom in choosing the location of your modules, far from the house connection.Plug & Play: Ready for immediate use thanks to pre-assembled MC4-compatible connectors (no crimping needed).Safety set: The colour combination red (+) and black (-) prevents polarity errors over long distances, where you might often lose track.Weatherproof (IP67): The plug connections are dustproof and waterproof; the insulation withstands extreme temperatures (-40°C to +90°C).UV- & ozone-resistant: The robust sheath made of cross-linked polyolefin does not become brittle even after years in the sun.Certified quality: Suitable for system voltages up to 1000V/1500V DC (TÜV/EN standards).Areas of applicationThe 20-metre extension is designed for extensive installations:Ground-mounted systems: Placement of the modules at the end of the property for optimum solar yield.Outbuildings: Connection from garden shed, carport or barn to the main house.Façade installation: Routing the cables from high roofs or façades down to the basement technical room.Shading management: Avoiding large sources of shade (trees, neighbouring buildings) by installing panels further away.Installation & safety instructionsNote voltage drop: With 20 metres length (40m current path there and back), resistance occurs. For grid-connected high-voltage systems (strings with several modules, >100V) 4mm² is unproblematic. For individual 12V/24V modules or standalone/off-grid systems, the loss at 4mm² is noticeable (approx. 3-5%). A 6mm² cable would be more efficient here.Do not create coils: Never wind excess cable into tight coils under high current (induction heating). Instead, lay it in large loops.Mechanical protection: Never lay the cable of this length unprotected on the ground (lawnmowers, animals!). Use cable ducts or protective tubes.Strain relief: Secure the cable immediately after connecting it to the module so that the weight of 20m of cable does not pull on the junction box. Properties Product nameSolar extension cable set (20 m) Cable length**20.0 metres** (per cable) Cable cross-section**4.0 mm²** Cable type**H1Z2Z2-K** (solar cable) Rated voltage**1500 V DC** Conductor materialTinned stranded copper wire (class 5) Connector**MC4-compatible** (male/female) Protection class**IP68** (connected) Temperature range-40°C to +90°C Special featureSet: 1x red (+) / 1x black (-)  FAQs about the 20m solar extension cableIs 4mm² still sufficient for 20 metres in length?Depends on the application. For a typical "balcony power station" (approx. 30-40V module voltage), the loss at full load is around 3-4%. This is technically safe, but means a slight reduction in output. For high-voltage strings (e.g. 300V), the percentage loss is negligible. For 12V systems (campers/battery charging), the voltage drop is too high; here we recommend 6mm² or 10mm².Can I bury the cable?Only in protective conduit. The insulation is weather-resistant but not certified for direct burial (risks: stones, moisture, rodents). A simple PE empty conduit from a DIY store provides sufficient protection.Are the connectors compatible with every inverter?Yes. The MC4 standard is universal. The cables suit all common modules and inverters (Hoymiles, Deye, Growatt etc.).

The solar extension cable set (25 metres, 4mm²) is the solution for photovoltaic projects with extreme distances. If your solar modules need to be located in the sunniest place on the property – for example at the end of a large garden, on a distant barn or in an open field – and the inverter is to remain centrally in the house, this set bridges the distance safely and reliably.The set includes two high-quality, double-insulated solar cables: one red cable for the positive pole (+) and one black cable for the negative pole (-). Both ends are professionally pre-assembled with MC4-compatible plugs and sockets. Due to the considerable length of 25 metres, this set is primarily designed for systems with a higher string voltage (e.g. several modules in series or grid-connected balcony power plants) in order to keep line losses low.Highlights at a glanceMaximum range: With a length of 25 metres (50 metres in the circuit) you can also implement complex installation scenarios far from the house connection.Plug & Play installation: The cables are pre-assembled on both sides with MC4-compatible connectors, so no special crimping tool is required.Secure identification: The colour coding in Red (+) and Black (-) effectively prevents polarity mix-ups with such a long cable run.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 class IP67: When plugged in, the connectors are completely dustproof and protected against temporary submersion (rain/puddles).High-quality conductor: Tin-plated electrolytic copper ensures corrosion resistance and consistently good conductivity.Areas of applicationThis 25 metre extension is intended for specific scenarios:Ground-mounted systems: Ideal for installing modules far away in the garden or on a meadow where there is no shading from buildings.Outbuilding: Connection of distant garages, carports, sheds or stables to the main building.Indirect cable routing: When cables cannot be laid directly, but have to be routed around the entire house or through long empty conduits.Installation & Safety InstructionsVoltage drop (Important!): At 25 metres length, the total current path is 50 metres.For grid-connected systems (voltage > 30V) 4mm² is usually acceptable (loss approx. 3-5%).For 12V off-grid systems this cable is not suitable, as the voltage drop would be too high. Here, 10mm² or 16mm² would have to be used.Laying in the ground: Although the cable is weatherproof, it is not protected against mechanical influences (stones, rodents, spades).When laying underground, it is essential to use a protective conduit (KG conduit or flexible conduit).Avoid induction: Never wind excess cable into a coil while current is flowing, as this can lead to heat buildup.Lay excess lengths in wide loops ("meanders"). Properties Product nameSolar extension cable set (25 m) Cable length**25.0 metres** (per cable) Cable cross-section**4.0 mm²** Cable type**H1Z2Z2-K** (solar cable) Nominal voltage**1500 V DC** Conductor materialElectrolytic copper, tin-plated (class 5) Connector**MC4-compatible** (Male/Female) Protection class**IP68** (plugged) Temperature range-40°C to +90°C Scope of delivery1x cable Red (+) / 1x cable Black (-) FAQs about the solar extension cable 25mIs 4mm² really sufficient at 25 metres length?Yes for high-voltage systems, no for 12V systems. With a typical balcony power plant (approx. 30-40V module voltage, approx. 10A current) you will have a voltage drop of approx. 2 volts. This means a power loss of about 4-5%. This is technically safe, but not optimal. If you need every watt, you should upgrade to 6mm² cable at this length. For a 12V battery application, almost 1 volt would be lost – that's too much!Will the connectors fit my inverter from Hoymiles or Deye?Yes. The connectors used correspond to the MC4 standard, which is used for almost all solar modules and micro inverters worldwide. They fit mechanically and electrically perfectly.Can I shorten the cable?Yes, but with effort. You can cut the cable to the required length. Please note, however, that you will then need new MC4 connectors and a special crimping tool to reassemble the connection.

Due to the massive length of 50 metres (100 metres total in the circuit), this set is designed exclusively for systems with very high string voltage to keep percentage line losses within acceptable limits.Highlights at a glanceMaximum range: With a length of 50 metres per cable, you can also realise extremely far-reaching installation scenarios far from the house connection.Plug & Play installation: The cables are 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 dangerous polarity confusion over this extremely long laying distance.Weatherproof & durable: The special sheath made of cross-linked polyolefin is UV-resistant, ozone-resistant and withstands extreme temperatures from -40°C to +90°C.Protection class IP67: The plug connections are absolutely dust-tight and protected against temporary submersion (e.g. in heavy rain or puddles) when plugged in.High-quality conductor: Tin-plated electrolytic copper ensures maximum corrosion resistance and permanently excellent conductivity.Areas of applicationThis 50-metre extension is intended for specific scenarios:Large open-space systemsIdeal for setting up modules far away on a meadow or at the edge of a property where there is no shade from buildings or forest edges.Agriculture & outbuildingsConnecting distant barns, stables or pumping stations to the main building.Indirect cable routingWhen cables cannot be laid directly, but must be routed over long detours around obstacles or through long empty conduit systems.Assembly & safety instructionsVoltage drop (Extremely important!)At a length of 50 metres, the total current path is 100 metres. For grid-connected systems with very high string voltage (> 200V), 4mm² is technically possible. For 12V or 24V stand-alone systems, this cable is absolutely unsuitable due to the massive voltage drop; your consumers would hardly get any energy here.Laying undergroundAlthough the cable is weatherproof, it is not protected against mechanical influences (spade cuts, rodents). When laying underground, you must use a high-quality protective conduit (e.g. cable protection pipe).Avoid induction & heatNever coil excess cable tightly while current is flowing, as this can cause induction and heat development. Lay excess lengths in large loops. Features ModelSolar extension cable set (50m) Conductor cross-section**4.0 mm²** Cable length**50.0 metres** (per colour) Rated voltageUp to 1500 V DC Plug type**MC4 compatible** (IP67) Conductor materialCopper, tinned (finely stranded) Temperature range-40°C to +120°C (on the conductor) StandardisationTÜV / EN 50618 (H1Z2Z2-K) Special featureUV- & ozone-resistant, halogen-free  FAQs about the solar extension cable 50mDoes 4mm² still make sense at 50 metres in length?For standard balcony power plants rather no.

The built-in connectors comply with the worldwide MC4 standard, which is used in almost all modern solar modules and microinverters. They fit perfectly both mechanically and electrically.Can I shorten the cable if necessary?Yes, but only with expertise. You can cut the cable. However, please note that for the new connection you will need professional MC4 connectors and a special crimping tool to ensure a permanently reliable and watertight connection.
