PV1-F 6mm² solar cable with MC4 connectors already crimped on both ends. Rated at 1500V DC, it handles higher system voltages and currents than standard 1000V cables. The 6mm² cross section supports up to 70A – suitable for high-power panels (500W+) or long string runs where voltage drop must stay low.

Key features

• 1500V DC system rating – works with modern high-voltage string inverters (Huawei, Sungrow, SMA).

• 6mm² tinned copper – 70A ampacity. 30% lower voltage drop compared to 4mm² over same distance.

• MC4 connectors pre-attached – type IV compatible, locking latch with audible click.

• IP68 waterproof – dust-tight and submersible. Direct burial or exposed outdoor runs.

• UV resistant cable and connector – no cracking after years of sunlight exposure.

• Halogen-free XLPO insulation – low smoke, non-toxic fumes per IEC 60754-1.

Applications

• String connections in 1500V DC solar farms (utility scale)

• Long DC runs from far array sections to combiner box

• High-current strings (e.g., bifacial panels → 13–15A per string, multiple strings in parallel)

• Replacement for damaged pigtails on existing modules

• Portable solar kits for RVs, boats, or off-grid cabins where 6mm² provides headroom for future expansion

FAQ

Q1: Can this 6mm² cable handle 1500V DC?
Yes. PV1-F 6mm² is rated for DC 1.8kV core-to-core. 1500V DC is within safe operating range.

Q2: What is the maximum continuous current?
Cable: 70A at 30°C ambient (free air). Connector: 50A. The connector is the limiting factor. For >50A, use a higher-rated connector or dual cables.

Q3: Are the MC4 connectors genuine Staubli?
Unless specified, the standard version uses TUV-certified generic MC4 compatible connectors. Original Staubli available at extra cost. Ask for quote.

Q4: Can I cut the cable to a shorter length and re-crimp?
Yes. Cut with standard cable shears, strip 8–10mm of insulation, and crimp a new MC4 contact using a 6mm² die. Keep the connector housings for reuse.

Q5: What is the voltage drop per 100 meters?
Conductor resistance ≤3.39 Ω/km. For 30A load, drop per 100m (one way) = 3.39×0.1×30 = 10.17V. For 1.2% of 1500V, acceptable. For 50A load, drop = 16.95V (1.13%). Still fine for most systems.

Q6: Is this cable suitable for direct burial?
Yes, if IP68 rated and protected from rocks or digging tools. Use conduit in rocky soil or high-traffic areas.

Q7: Does the cable stay flexible in cold weather?
Yes. Class 5 stranding (84 fine wires) keeps flexibility down to -40°C. No cracking.

Q8: What certifications are included?
Cable: TUV EN50618. Connector: IEC 62852 TUV. CE, RoHS, REACH.

Q9: How long is the service life?
25 years under nominal outdoor conditions (UV, temperature cycles, moisture).

Q10: Can I use this cable for AC side wiring?
No. This is for DC photovoltaic circuits only. For AC side, use standard AC cables rated for local electrical codes
