This pair of solar photovoltaic connectors is rated 1000 V DC and 30 A with IP67 waterproofing and an operating range from -40 °C to +85 °C, making them suitable for outdoor PV strings on rooftops, RVs, vans, boats, and off-grid solar setups. Tinned-copper contacts crimp onto 2.5 to 6 mm² solar cable, and the PPE housing is rated UL94-V0 for flame resistance.
Product Description
This is one matched pair (male + female) of solar photovoltaic connectors designed for series and parallel wiring of PV modules. The body is PPE plastic, the contact is tinned copper, and the assembled connector seals to IP67 against dust and immersion when properly crimped to a sized solar cable. The intended use is connecting solar panel output leads to MC4-compatible interconnects, charge controllers, and combiner boxes in residential rooftop, mobile (RV, boat, caravan), and off-grid installations.
Insertion and withdrawal forces are specified at ≤50 N and ≥50 N respectively, which is the standard handling envelope for PV connectors and ensures the joint will not back out under cable weight or thermal cycling. The connectors are intended to be crimped with a proper PV crimping tool — they are not solder-on, and the contact relies on cold-weld crimping for its current rating.
Key Benefits
- 1000 V DC / 30 A rating covers virtually all residential and small-commercial PV strings
- IP67 waterproof and dust-tight for rooftop and outdoor mobile installations
- Wide -40 °C to +85 °C operating range covers desert, alpine, and tropical climates
- UL94-V0 flame-rated PPE housing meets standard PV component fire safety
- Tinned copper contacts maintain low resistance over years of exposure
Key Features
The defining feature is the contact-and-housing pairing: tinned copper inside a UL94-V0 PPE shell. Tinned copper resists oxidation in humid and salt-air environments — important for boat, coastal, and rooftop installs — while UL94-V0 is the highest household flame-resistance rating, meaning the housing self-extinguishes within seconds and does not drip flaming material if exposed to a flame. The IP67 seal is achieved when the connector is properly crimped to a 2.5–6 mm² solar cable; the rating does not apply to a partially-mated or improperly-crimped joint.

Compatibility & Applications
This pair is mechanically and electrically compatible with the standard PV connector form factor used industry-wide and pairs with most equivalent connectors from other manufacturers. Typical applications include:
- Residential rooftop solar panel interconnects
- RV, caravan, van, and boat solar installations
- Off-grid cabin and remote-monitoring PV systems
- Mobile and portable solar charging stations
- Solar charge controller input wiring
Not compatible with: cables outside the 2.5–6 mm² range (won't crimp securely), AC household wiring (not rated for AC use), and any application above 1000 V DC or 30 A continuous.

Frequently Asked Questions
Are these connectors compatible with the industry-standard PV connector format?
Yes. They use the same physical and electrical interface as the industry-standard 1000 V / 30 A PV connector that has become the de facto worldwide format for residential and small-commercial solar wiring, and they will mate with most equivalent connectors from major PV brands.
Do I need a special crimping tool?
Yes. PV connectors require a crimping tool with the correct die for 2.5–6 mm² solar contacts. A generic terminal crimper or pliers will not produce a gas-tight cold-weld joint and will not achieve the rated current capacity or IP67 seal. Buy or borrow a PV-rated crimper before installation.
What cable size should I use?
4 mm² (~12 AWG) is the most common solar cable for residential rooftop strings up to about 30 A; 6 mm² (~10 AWG) is used for higher-current parallel runs or longer cable lengths to reduce voltage drop. 2.5 mm² (~14 AWG) is fine for low-current portable panels under 15 A.
How fast does shipping take?
Orders are dispatched from regional fulfillment partners in North America, Europe, and Asia. Typical delivery is 5 to 15 business days depending on destination country, with tracked shipping included. Specific timelines per destination are listed in the Shipping Policy.
How does this connector pair compare to others in its category?
Within the PV connector category, the meaningful comparison points are voltage and current rating, environmental seal, and housing flame rating. This product is rated 1000 V DC / 30 A with IP67 and UL94-V0 — the configuration that fits the broadest base of residential rooftop and mobile solar installations and drives the lowest return rate within our renewable-energy components category.
