Product Overview
A connector pair — and the harnesses built from it
This page covers one product family in two forms. The first is the MC4-compatible connector pair itself: a male and a female single-pole connector with a Ø 4 mm contact system, a snap-in bayonet lock and a dual seal, designed to the IEC 62852 requirements for connectors used on the DC side of photovoltaic systems. The second is the pre-terminated harness — the same connectors crimped onto H1Z2Z2-K or PV1-F solar cable in our own assembly shop, delivered cut to the length your drawing calls for.
Contacts are tinned copper with 99.98 % copper purity. Tinning keeps the contact surface stable in humid, coastal and polluted sites and is what makes the difference between a connector that survives fifteen years on a rooftop and one that does not. The housing is PPO / PPE rated UL94 V-0, and the mated pair is sealed to IP68 — 1 m depth for 1 hour, so a string can be walked on, hosed down and left out in the rain without water reaching the contact.
Read the ratings with their basis attached. Continuous current through the pair is 30 A, with a 50 A peak rating. The DC voltage is 1100 V under IEC 62852:2014+Amd1:2020; the 1500 V class is reached under UL 6703 and the TÜV specification 2 PfG 2330/03.2023, and 1500 V IEC use is restricted to access-controlled areas. Safety class follows the same split — Class II at 1100 V, Class 0 at 1500 V — which is normal IEC practice and is explained in the specification notes below.
One point we state plainly because the industry usually does not. MC4 is a registered trademark of Stäubli, and every connector manufacturer — Stäubli included — instructs users not to mate one brand's male half with another brand's female half. Our connector is a compatible 4 mm contact system, so it fits MC4-type interfaces, but on a mated pair we recommend keeping SORIVO male with SORIVO female. Mixed-brand pairs are the root of most DC arc-fault failures in the field, and no cross-mating is covered by any IEC 62852 approval.

Key Features
Eight things that decide whether a DC joint survives
IEC 62852 Connector Design
Designed to the IEC 62852 requirements for connectors on the DC side of photovoltaic systems — the same document test houses use to type-approve a PV connector.
IP68 When Mated
Verified at 1 m depth for 1 hour with the pair locked together. A dual seal closes on the cable jacket and on the mating face, so water never reaches the contact.
4 mm MC4-Compatible Interface
A Ø 4 mm single-pole contact system that fits MC4, Standard4 and PV4-type interfaces. Keep both halves of a mated pair the same brand — see the note in the specification.
Tinned Copper Contacts
Copper contacts at 99.98 % purity, tin-plated, with a contact resistance of ≤ 0.5 mΩ. Low joint resistance is what keeps a 15 A string from cooking its own connector.
PPO / PPE, UL94 V-0
Flame-retardant PPO / PPE housing rated UL94 V-0, with the dimensional stability to hold the locking geometry through years of thermal cycling.
Crimped Contact, Tool-Free Mating
The copper contact is crimped to the conductor with the matching tool — that joint is what carries the current. Push-fit mating needs no tool; opening a locked pair needs a release tool.
−40°C to +85°C
Operating range of −40°C to +85°C with a 6 kV AC test voltage at 50 Hz for 1 minute. In a harness, the assembly temperature range is set by the connector, not the cable.
Connector or Finished Harness
Order loose pairs in bulk for your own assembly line, or order them crimped to H1Z2Z2-K or PV1-F cable at any length from 0.3 m to 50 m.

Table 1 Cable sizes the connector accepts, and the harness rating you get
| Cable size mm² | AWG | Conductor | Cable outer dia. max. mm | Max. DC resistance at 20°C, Ω/km | Cable ampacity free air 60°C, A | Harness rating connector-limited, A |
|---|---|---|---|---|---|---|
| 4 | 12 | Class 5 tinned Cu | 5.9 | 5.09 | 55 | 30 |
| 6 | 10 | Class 5 tinned Cu | 6.4 | 3.39 | 70 | 30 |
The 4 mm² row is highlighted — it is the size this page is built around and the size we keep in stock; 6 mm² is produced to order. The harness rating is set by the connector, not the cable: moving from 4 mm² to 6 mm² lowers voltage drop and resistance, but it does not raise the 30 A continuous rating of the pair. Cable-dimension, resistance and ampacity columns are the published H1Z2Z2-K values (EN 50618 Table A3, 60°C ambient, single cable in free air) for the SORIVO solar cable used in these harnesses.

On the 1500 V rating: under IEC 62852:2014+Amd1:2020 the connector is rated DC 1100 V; the 1500 V DC class is published under UL 6703 and the TÜV specification 2 PfG 2330/03.2023, and IEC 1500 V use is intended for PV systems in access-restricted areas. On safety class: the safety class of a PV connector follows the voltage — Class II at DC 1100 V and Class 0 at DC 1500 V under IEC practice. The exact class printed on the certificate for your part number is what applies, so confirm it with us before specifying a 1500 V DC string. On the MC4 name: MC4 is a registered trademark of Stäubli. SORIVO connectors are compatible accessories and are not Stäubli products. Connector manufacturers, Stäubli included, instruct users not to mate one brand's connector with another brand's; we recommend using SORIVO male and female halves as a pair, and we will not warrant a mixed-brand mated pair.

Transparency note: certification status and exact scope should always be confirmed against the certificate for the specific part number. Ratings for PV connectors are published per standard body and per voltage class, so the 1500 V DC figure in particular must be read together with the standard it comes from. We provide the certificate and test reports with every quotation — no blank promises.
Quality & Factory
Connector and cable from the same factory
Contact, housing and crimp are controlled under one roof, so the joint you receive is the joint we tested.
- 1Incoming material control — contact blanks, housing compound and tinned copper conductor are checked before the run starts.
- 2Crimp process control — the crimp height and pull-out force of the contact-to-conductor joint are monitored against the tooling specification.
- 3Routine electrical tests — contact resistance, insulation and the 6 kV AC withstand test are applied to the connector; finished harnesses get a 100 % continuity and polarity check.
- 4Batch documentation — test records are retained per batch and supplied with the order on request.

FAQ
Questions buyers ask before ordering
MC4 is a registered trademark of Stäubli, and SORIVO supplies a compatible accessory, not a Stäubli product. Our connector uses the same Ø 4 mm contact system, so it fits the MC4, Standard4 and PV4-type interfaces that dominate the market. One caveat we will not hide: Stäubli's own assembly instructions state that the male or female part of their connector must never be mated with another manufacturer's connector, and the same logic applies in reverse. Use SORIVO male with SORIVO female. Mixed-brand pairs are outside every IEC 62852 approval and are a known cause of DC arc faults. If your project is contractually tied to a specific brand's connector, tell us and we will quote the harness with the cable only.
Yes. The pair is available loose in bulk for your own crimping line — that is how most panel builders and harness houses buy from us. We also supply the same pair already crimped to cable. If you need the finished assembly rather than the loose connector, our 4 mm² solar extension cable with MC4 connectors is the stock product built for that job, cut to any length from 0.3 m to 20 m.
Not through this connector. The pair is rated 30 A continuous with a 50 A peak, and the assembly rating is the lower of the cable and the connector — so a 6 mm² harness is still a 30 A harness. What the larger cross-section buys you is lower resistance and lower voltage drop: 3.39 Ω/km against 5.09 Ω/km for 4 mm², and an outer diameter of 6.4 mm against 5.9 mm. Choose 6 mm² on long runs where voltage drop decides the design, not because you expect more current through the connector.
With the right basis attached, yes. Under IEC 62852:2014+Amd1:2020 the connector is rated DC 1100 V. The 1500 V DC class is published under UL 6703 and the TÜV specification 2 PfG 2330/03.2023, and IEC 1500 V use is intended for PV systems in access-restricted areas. Safety class follows the voltage too — Class II at DC 1100 V and Class 0 at DC 1500 V — so if your string design assumes Class II insulation at 1500 V, that assumption needs rechecking. Tell us the system voltage and the destination market and we will confirm the exact rating basis for your part number in writing.
Two different answers, and it matters. Fitting is tool-free — the pair pushes together and the bayonet lock snaps home. Crimping is not: the copper contact is crimped onto the conductor with the matching crimp tool, and that joint, not the plastic housing, is what carries the current. Opening is not tool-free either — a locking-type connector of this design requires a release tool, which is what NEC 690.33(C) asks for and what stops a live string being pulled apart by hand. Never disconnect under load.
No connector standard states a service life in years, so we will not quote one. What is specified is what the connector is built to survive: a PPO / PPE housing rated UL94 V-0, tinned copper contacts that resist corrosion, a −40°C to +85°C operating range, and IP68 sealing with the pair mated. Mating and unmating is what actually ages a field connector, so design the array to be commissioned and left alone. The cable these harnesses are built from, H1Z2Z2-K, carries the 25-year minimum design life that EN 50618 requires — the H1Z2Z2-K solar cable page has that data.
The connector is designed to the IEC 62852 requirements, and the 1500 V DC rating is published under UL 6703 and TÜV 2 PfG 2330. Housing flame class is UL94 V-0 and the mated pair is sealed to IP68 at 1 m for 1 hour. We provide the certificate and test reports with the quotation, and we confirm the exact scope against the certificate for your part number rather than describing it in the abstract. If your project needs a specific listing for a specific market, say so at inquiry stage — it is far cheaper to confirm it before production than after.
Yes. SORIVO can arrange sample orders of loose pairs or finished harnesses for fit and crimp qualification. Availability and lead time depend on the cable size, cable type and length you need, and on current stock. Standard 4 mm² lengths may be available within a few working days, while custom lengths and 6 mm² assemblies require additional production time. MOQ for production is 100 sets, and sample quantities are negotiable.
