LAPP Product Portfolio – Solar Cables, Connectors and Industrial Connectivity

LAPP’s portfolio extends well beyond photovoltaic DC cable.

Some products belong to the manufacturer’s wider industrial portfolio rather than the current 3Buy Solar catalogue.

LAPP Official Solar Energy Product Portfolio

LAPP ÖLFLEX SOLAR H1 BUR – H1Z2Z2-K Photovoltaic Cable

ÖLFLEX SOLAR H1 BUR is a dedicated photovoltaic cable family designed for solar DC applications.

LAPP describes the product as an H1Z2Z2-K solar cable suitable for PV module connections, solar generator wiring and specified direct-burial configurations.

Its construction uses flexible conductors and cross-linked insulation and sheath materials intended for demanding operating environments.

ÖLFLEX SOLAR H1 BUR – Manufacturer Technical Characteristics

The manufacturer’s expected 25-year service life is an engineering statement under specified conditions, not an automatic 25-year commercial warranty.

ÖLFLEX SOLAR H1 BUR – Common Cable Sizes

Selected LAPP article references include:

These examples refer to selected black-sheath H1 BUR versions. Red, blue or other configurations may use different article numbers.

Direct Burial and Underground Installations

One of the distinguishing features of the H1 BUR family is LAPP’s published allowance for specified underground applications.

These include installation in protective conduits and certain cable-trench configurations when the applicable installation rules are met.

This is not permission to bury every LAPP solar cable without protection.

Installation suitability depends on the exact product, mechanical protection, trench arrangement, soil conditions and local electrical regulations.

• Rated voltage.
• Conductor size.
• Insulation and sheath construction.
• Temperature limits.
• Water-resistance qualification, where required.
• UV exposure and weathering requirements.
• Permitted installation method.
• Applicable certification and documentation.

For specialist rooftop, ground-mounted or water-exposed installations, a general statement that a product is an outdoor solar cable does not establish suitability for permanent immersion, moving structures or unrestricted underground burial.

LAPP Renewable Energy and Solar Cable Range

LAPP Solar Cable Sizes – 4 mm², 6 mm², 10 mm² and 16 mm²

Selecting the correct conductor cross-section is essential for PV string safety and efficient energy transmission.

Cable sizing depends on actual circuit conditions rather than simply the inverter’s advertised power.

These are application examples, not universal ampacity approvals.

LAPP 4 mm² Solar Cable

4 mm² cable may be appropriate for PV module strings where the actual current, route length, ambient temperature and installation method permit it.

LAPP 6 mm² Solar Cable

6 mm² cable is often considered for longer string runs or lower voltage-drop requirements.

It may reduce resistive losses compared with 4 mm² cable of equivalent conductor material and length.

LAPP 10 mm² Solar Cable

10 mm² cable may be appropriate where project design requires larger conductor capacity or reduced electrical losses.

It is relevant to commercial rooftops, longer DC cable runs and selected larger solar installations.

LAPP 16 mm² Solar Cable

16 mm² solar cable can be considered for approved higher-current or longer-distance applications.

Termination compatibility and available connector sizes become particularly important as conductor cross-section increases.

Buy LAPP Solar Cable Reels at 3Buy Solar

3Buy Solar lists four 10 mm² solar DC cable products in different colours and reel lengths. LAPP appears as one of the manufacturer options on these shared product pages.

Important for buyers: These are multi-manufacturer product listings. Select the LAPP manufacturer option and confirm that the cable variant, cable marking, associated datasheet and delivery quantity match your specification before ordering.

The product listing should not be interpreted as confirmation that every manufacturer option is in stock merely because the parent product displays an availability status.

Why Buy Solar Cable by the Reel?

For professional installers and EPC contractors, reel procurement offers several practical advantages:

• Fewer repeated small cable orders.
• Easier material allocation across projects.
• Improved quantity planning.
• Potentially fewer unnecessary cable joins.
• Consistent stock for repeated installations.
• Simpler site delivery and inventory control.

The correct reel format depends on the project cable schedule, route lengths and cutting plan.

LAPP Solar Cable Sizing – Current, Voltage Drop and Cable Losses

Cable sizing should follow the relevant electrical standards and the manufacturer’s product data.

For a simplified two-conductor DC copper circuit, voltage drop can be estimated using:

Voltage drop ≈ 2 × one-way length × current × conductor resistivity ÷ conductor area

For illustration, assume:

• 30 m one-way cable length.
• 15A DC current.
• Copper conductor resistivity of 0.0175 Ω·mm²/m at approximately 20°C.

These are illustrative calculations. They are not manufacturer-tested resistance values or final cable-sizing approvals.

Real conductor resistance increases with temperature.

Professional electrical design must also account for:

• Correct conductor resistance at operating temperature.
• Installation grouping.
• Ambient temperature.
• Cable support and routing.
• Current-carrying capacity.
• Fault protection.
• Equipment terminals.
• Voltage-drop limits.
• Relevant standards and design requirements.

When Is a Larger Cable Economical?

Increasing conductor area can reduce voltage drop and resistive losses, but it also increases material cost and can affect termination equipment.

An installer should evaluate the cost of larger cable against expected lifetime energy savings and installation requirements.

For commercial PV, even modest cable losses can become relevant over the system’s operating life.

LAPP EPIC SOLAR Connectors – Professional PV DC Connections

EPIC SOLAR is LAPP’s dedicated photovoltaic connector technology.

The manufacturer also documents EPIC SOLAR 4 GEN2 connector solutions and associated contacts, splitters and patch assemblies.

These products are relevant to PV generator wiring where connectors must provide suitable electrical performance, environmental protection and reliable field termination.

EPIC SOLAR 4 GEN2

The LAPP infrastructure portfolio identifies:

• EPIC SOLAR 4 GEN2 female and male connectors.
• EPIC SOLAR 4 GEN2 contacts.
• EPIC SOLAR 4 GEN2 splitters.
• EPIC SOLAR 4 GEN2 patch assemblies.

The appropriate connector must be chosen according to:

• Cable outside diameter.
• Conductor cross-section.
• Rated DC voltage.
• Current rating.
• Permitted mating system.
• Required crimping tool.
• Environmental protection.
• Manufacturer assembly instructions.

EPIC SOLAR and MC4 Connector Compatibility

Solar PV connectors that appear physically similar are not automatically approved for cross-mating.

Before connecting LAPP EPIC products to an existing photovoltaic module connector, verify the exact approved connector pair.

Unapproved cross-mating can result in poor contact, increased resistance, overheating or compromised sealing.

Modern photovoltaic electrical infrastructure is evolving alongside higher-power modules, larger rooftop projects and more sophisticated energy systems.

Higher-Voltage Solar Arrays

1500V-class photovoltaic systems are important in large commercial and utility applications.

All electrical components must support the actual system voltage, not only the cable.

High-Current Solar Modules

Increasing module and string currents make conductor sizing and connector selection increasingly important.

Pre-Assembled Harnesses

Factory-prepared PV cable assemblies can support repeatability and reduce on-site termination work where the design is correct.

Industrial Monitoring

Commercial PV, battery storage and EV charging increasingly rely on Ethernet, fibre-optic and control networks.

LAPP’s ETHERLINE, UNITRONIC and HITRONIC families are relevant to this development.

Documentation and Traceability

Large EPC projects benefit from exact article references, manufacturer test evidence, cable identification and systematic procurement.

Environmental Durability

Demanding installations may require specialist cable constructions for underground routing, water exposure, abrasion, temperature or mechanical protection.

LAPP’s different ÖLFLEX SOLAR families should be compared according to these actual requirements rather than treated as interchangeable.
