KBE is a German cable manufacturer whose solar range uses specific construction names. Our Premium selection is SOLAR DB: the full reference, conductor section and supplied test records matter more than simply recognizing a black or red reel.
Authenticated manufacturer example. The selected product reference determines appearance and ratings.
01 / Who they are
Cable manufacturing since 1980.
KBE Elektrotechnik was founded in Berlin in 1980, initially making electrical wires and PVC profiles. Its later cable business expanded into photovoltaics, automotive, industrial and charging applications. The manufacturer describes more than fifteen years of solar-cable experience, but the reviewed dated records do not establish an exact first PV-cable production year. The present solar offer includes DB+, specialised burial/trench constructions and floating-PV cables. Those application branches are more useful to system design than treating the company’s founding date as solar-product age.
The manufacturer’s corporate origins are not the manufacturing country of every supplied device. Read the exact label and documents.
Business development and revenue
KBE’s 2025 anniversary describes a medium-sized independent manufacturing group with a substantial cable-production base. Production capacity is not revenue, and includes applications beyond solar. No reliable public annual revenue series through 2025 was found for the manufacturer; the business history and documented cable constructions are presented without a fabricated financial trend.
No verified public annual revenue series through 2025 was identified. Milestones describe business development, not a measured revenue trend.
Business milestones
Wires and profiles in Berlin
The original business makes electrical wires and PVC profiles. Solar cables are a later development, not the first 1980 product.
Wire production · illustrative example, not a photograph of this milestone.
Manufacturing quality systems develop
KBE records ISO/TS 16949 certification, later transitioned to IATF 16949. This concerns manufacturing quality systems, not a solar-cable lifetime warranty.
SOLAR DB · illustrative example, not a photograph of this milestone.
Solar cables are a core business
The dated anniversary publication identifies DC solar cables as a core activity. The contemporary DB+ and specialist constructions address distinct installation conditions.
Floating solar cable · illustrative example, not a photograph of this milestone.

SOLAR DB example; not every variant
01
SOLAR DB
Our listed solar DC construction
The website product page groups documented cross-sections while retaining the exact SOLAR DB designation and applicable certificates. The listed SOLAR DB H1Z2Z2-K follows its retained EN 50618 / IEC 62930 documentation. Its voltage class and double insulation describe the cable construction; they do not set permissible current for every 4, 6 or 10 mm² route. Installation method and thermal conditions govern ampacity.
Options change conductor area, not the identity of the cable family.
Adjacent DB+ or floating-cable claims are not transferred here.
02
Other solar constructions
Broader manufacturer offerings
The official solar portfolio distinguishes additional constructions. They explain the brand’s breadth, not products automatically supplied by ReneWave. SOLAR DB+ adds product-specific suitability for demanding routes such as direct burial and permanent water exposure in the manufacturer’s EPC portfolio. The published ≥25-year design life is not a 25-year product warranty. Do not transfer DB+ permissions to the listed DB reference without its own certificate.
A suffix can change the applicable construction record.
Use the documentation tied to the delivered reference.
Key terms
Short definitions for the names used in this guide.
SOLAR DB / mm²
Family designation identifies construction. mm² identifies conductor area; it does not by itself establish the installed current limit.
A current rating alone does not establish function, fault protection or circuit suitability.
03 / What stands behind the brand
Premium
Why this selection carries Premium.
A few documented reasons without a blanket lifespan claim.
Our positioning applies to the selected range. The documented differences above explain the choice.
An identifiable manufacturing history
The company’s anniversary record dates its business to 1980. This establishes company history, not field life of the current cable.
Exact construction and test records
Our retained SOLAR DB documents keep the declared construction and certificates tied to the actual listed reference.
A certificate has a defined scope
SOLAR DB and DB+ permissions must remain attached to the exact construction. We check the cable’s own documents for a demanding installation, rather than importing direct-burial or water-exposure permissions from a neighboring product.
Published characteristics are useful evidence, not a promise of trouble-free operation or fast local warranty handling. Newer models do not inherit decades of field history from the company’s age.
The exact reference, market and supplied terms govern coverage. A datasheet or compliance certificate is not itself a warranty.
Coverage depends on the supplied terms
A universal manufacturer warranty duration for the listed references was not verified. Product defects are assessed under the applicable supplied warranty; protection coordination, installation faults and misuse are separate matters.
Product cover and system performance
Manufacturer product cover concerns qualifying defects in the supplied equipment. It does not establish the complete installation’s performance, an energy-yield guarantee or a fixed local claim-response time.
Questions before you buy
Do not assume so. Read the complete designation and its own technical sheet.
No. Test conditions and written warranty terms are different evidence.
Color alone cannot identify construction, reference or certification.
