Once properly pressed on, they are firmly in place and windproof.

The Mounting Systems end clamp is a specialised fastening element that secures the end of a row of solar modules to the substructure. In this version, it is designed as a universal clamp that flexibly covers module frame heights from 30 to 40 mm. The specification "40 mm" refers to the width of the clamping surface or the length of the clamping body to ensure optimum force distribution on the frame.Thanks to the sophisticated design, the clamp automatically adapts to the respective frame thickness when tightened. This makes it an extremely efficient solution for installers, as only one clamp model needs to be stocked for different module types.Highlights at a glanceVariable clamping range: Suitable for all standard solar modules with a frame height between 30 mm and 40 mm.High stability: The 40 mm wide clamping surface ensures a secure hold and protects the module frame against point loads.Robust materials: Made from weather-resistant aluminium and stainless steel screws, ensuring permanent corrosion resistance.Easy adjustment: The elongated hole or integrated spring allows the clamp to be precisely positioned and tightened at the end of the rail.Universal compatibility: Suitable for standard Mounting Systems profile systems and comparable aluminium mounting rails.Secure row termination: Ensures that the outer modules remain firmly attached to the rail even at extreme wind speeds.Areas of applicationThe end clamp is used exclusively at the outer ends of a module field:Photovoltaic roof installationsFor securing the first and last module of a row on pitched or flat roofs.Single module installationFor installations of individual modules (e.g. balcony systems), a total of four end clamps are required, as there is no module transition.Commercial PV parksFor use in large-scale systems where fast and reliable installation of the module termination is required.Installation & safety instructionsCorrect positioningThe clamp must be flush with the module frame. Ensure that the clamping foot is securely anchored in the mounting rail slot.Tightening torqueTighten the screw with the torque recommended by the system manufacturer (usually between 8 and 10 Nm) to achieve optimum clamping force without deforming the material.Overhang of the railAllow the mounting rail to protrude approx. 2–5 cm beyond the module to provide sufficient space for the end clamp to anchor stably. Properties CategoryEnd clamp alu natural Clamping range (frame height)30 – 40 mm MaterialAluminium (high-strength) Colour / FinishAlu natural (silver) Clamp length40 mm Area of applicationEnd fastening of the module field CompatibilityMounting Systems rail profiles Mounting typeClick or screw fixing Weather resistanceUV-resistant and corrosion-resistant  FAQs about the Mounting Systems end clampCan I use this clamp between two modules as well?No.Between two modules, centre clamps must be used as these fix both frames at the same time. The end clamp is shaped on one side only to hold just one frame at the end of the rail.Does the clamp fit both 30 mm and 40 mm frames equally?Yes.The mechanism is designed so that the clamp can be continuously tightened within this range. You just need to screw in the bolt until the clamping arm rests firmly on the module frame.Is this clamp also available in black?Yes.For full-black modules, Mounting Systems also offers this model in a black anodised version, so the fastening is not visually conspicuous on the dark frame.Is the clamp supplied as a set with screw and sliding block?As a rule, yes.Most variants are delivered as ready-to-install sets. However, please check in advance whether the included sliding block or click block (EC) matches your specific rail profile.

The solar extension cable set (20 metres, 6mm²) is the high-performance solution for photovoltaic projects where maximum efficiency and minimum losses over long distances are paramount. If you need to bridge a distance of 20 metres between your solar modules and the inverter, this generous cross-section of 6mm² offers the necessary reserves to safely transmit the generated energy to its destination without any significant heat build-up.The set contains two high-quality, double-insulated solar cables: a red cable for the positive pole (+) and a black cable for the negative pole (-). Both ends are professionally fitted with MC4-compatible plugs and sockets. The solid cross-section makes this set particularly future-proof and ideal for modern high-performance modules, which often deliver high currents and where standard cables already reach their limits at this distance.Highlights at a glanceLowest line losses: The cross-section of 6mm² drastically reduces electrical resistance and ensures a much lower voltage drop than conventional 4mm² cables over 20 metres.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 incorrect polarity and makes installation easier even with more complex systems.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.IP67 protection class: The connectors are absolutely dustproof when plugged in and protected against temporary submersion (rain/puddles).High-quality conductor: Tinned electrolytic copper ensures excellent corrosion resistance and permanently high conductivity, even in demanding environments.Areas of applicationThis 20-metre extension is optimised for demanding long-distance connections:Large balcony power plants & garden systemsIdeal for placing modules at the sunny end of a garden or on a carport and routing the electricity with minimal loss over 20 metres to the house.Roof systems & barnsBridging the distance from far-off module strings to the point of entry into the building or to the central inverter.Off-grid systems (12V / 24V / 48V)Particularly critical for battery systems: At 20 metres, the 6mm² cross-section ensures that the charging voltage arrives almost loss-free, noticeably increasing the efficiency of your storage unit.Assembly & safety instructionsEfficiency advantage over distanceAt 20 metres cable length, 6mm² offers a significant advantage over 4mm². The lower resistance provides a higher system voltage at the inverter and thus measurably more yield.Strain relief & fixationFasten the long cable paths every 50-100 cm with UV-resistant cable ties to the mounting frame or in cable ducts to avoid mechanical strain on the connectors.Correct lockingWhen connecting, make sure that the MC4 connectors audibly engage. Only then is the connection permanently watertight and safe against dangerous arcing. Features ModelSolar extension cable set (20m / 6mm²) Conductor cross-section**6.0 mm²** Cable length**20.0 metres** (per colour) Nominal voltageUp to 1500 V DC Connector type**MC4 compatible** (IP67) Conductor materialCopper, tinned (fine stranded) Temperature range-40°C to +120°C (on the conductor) StandardisationTÜV / EN 50618 (H1Z2Z2-K) Special featureVery low resistance & loss-optimised FAQs about the solar extension cable 20m 6mm²Why should I choose 6mm² for 20m?To minimise power losses.
