MC4 Solar Connector Series
Reliable Photovoltaic Interconnection for Residential, Commercial, and Off-Grid Solar Systems
The dependability of fuse interconnection for residential, commercial, and off-the-grid solar systems.
Zion Communication ensures the supply of high-quality MC4 solar connectors, which are purposely made for fast and secure connection of PV modules. MC4 connectors designed for outdoor environments are far tougher: they are IP67/IP68 waterproof, climate-resistant, as well as compatible with the standard size of 4 to 6 mm² (10 to 12 AWG) solar cables.
Widely applicable to any power system for residential rooftops, generation farms, and RV solar setups, our MC4 connector series provides assured joint, a low-resistance connection, and a long-lasting.

Zion Communication provides a whole range of MC4-compatible connectors, especially devised to satisfy different wire configurations and load conditions. Below is a breakdown of the most commonly used types:
Application: Cable connections from solar panels to other panels or from strings to inverters.
Description:
The Standard MC4 has the widest application area in photovoltaic wiring of PV modules in series for more than 90% of existing panels. This type of connector is made to combine a male and female pair that can lock and be pulled out by other tools like rings. Compatible with conductors with a size of 4-6 mm² (10-12 AWG) PV cables, and it is the blue print of the most rooftops and ground-mounted systems.
Key Features:
Operated at 1000 V / 1500 V DC, 20-30 A current.
IP67 protection when connected.
Housing is UV-customized and premium quality flame-retardant.
Can work with any kind of MC4-Certified connectors.
IEC 62852 / UL 6703 / TUV verified.
Use Case: A home, business, and off-grid solar systems are higher voltage interconnections.
Application: PV large-scale systems and multi-string array.
Description:
The MC4-Evo2 is an ameliorated high-voltage version of the every-day MC4 that enabled also systems up to 1500V DC. The type of terminal is suitable for a copper conductor size up to 10 mm², making it fit for high power and long distance transmission.
Key Features:
Compatible with cable sizes of 6 to 10 mm² (8 to 10 AWG).
Rated voltage: 1500V DC (UL & IEC).
The contacts are silver-plated to minimize resistance.
Operation temperature range: −40 °C to +90 °C.
TUV, UL, CE approval.
Use Case: Solar utility scale installations, central inverter connection, and solar farms.
Application: In net technique, several PV modules are connected.
Description:
T-branched connectors redirect the process to get one PV output into two or three parasitic activities. These connectors help to organize the array layout, reduce the number of junctions, and are indispensable if you want to maximize inverter input possibilities.
Key Features:
Two-coupler (2-to-1), three-coupler (3-to-1), or uses unique configurations.
Overall IP67 protection, plus it is flame resistant.
Does not require tools for the fitting and removal.
This helps in parallel statements (alternation of strings to strand) without cutting or splicing the wires.
Use Case: Parallel configuration of solar panels, multi-modules systems, off-grid setups.
Application: In-line PV string protection in Solar Arrays.
Description:
This MC4 variant has an inbuilt side fuse to prevent solar strings' circuit breaker from tripping due to short-circuits or for reverse fault current. The fuse does not have to be removed from the system when it opens, and therefore, it is very suitable for distributed covering of solar arrays.
Key Features:
Available fuse ratings: 10A, 15A and 20A (also available tailored).
Rated voltage: UP TO 1000V DC.
Interchangeable fuse system.
High-temperature resistant, waterproof enclosure.
Use Case: Centralized or string-later PV protection, field inspection setups.
Application: Combine output of two solar panels with one wire.
Description:
The Y-connector is used to join two panel outputs in a single line, reducing the number of cables and simplifying the series and parallel hybrid connection. This is similar to MC4 T-branch connectors, which are widely used in more compact or mobile setups.
Key Features:
Configurations: M from F/MF to F/MN.
This ensures that two sources have the same current.
Heavy operating strength and outdoor stabilization.
This is applicable for standard MC4 connectors.
Use Case: RV or camper solar kits with dual panels; off-grid systems with multiple PV and mobile generators.
Application: Any expert as well as DIY installation of MC4 connectors.
Description:
Proper installation requires this kit to be here, which is the safe MC4 termination kit. The tools, which do not comply with the requirements, can affect negatively. As a result, there can be bad crimping or connector failure.
Kit Includes:
MC4 crimping tool (size should be 2.5 to 10 mm² cables).
A wire stripper used to excavate solar PV cables.
MC4 unlocking and disconnecting tool.
Additional male/female pins and seals (option).
Carrying case.
Use Case: Inverter installations, routine maintenance, or service of solar energy systems – solar professionals and installers.
✅ Universal Compatibility: Compatible with most modules ad inverters.
✅ Quick Installation: Join together with quick-lock preventing screw and audible click.
✅ Weatherproof Design: It is resistant to dust, moisture, and UV rays.
✅ Electrical Safety: Output polarity protection and low contact resistance.
✅ 25-Year Durability: High long-lasting output redundancy of solar modules.
✅ Certified Quality: Relation of the highest level of the requirement of solar standards.
Residential and commercial solar PV systems.
Camping and RV solar panels, cabins and yachts, rear generators.
Off-grid solar kits for RVs, cabins, and boats.
Some techniques for stringing PV arrays in series and parallel.
DIY solar kits and mobile solar solutions.
Hybrid fleet systems and energy storage installations.
⚠️ Installation Notes
Apply the IRS presentation of the MC4 tools for crimping and tightening.
Ensure the connections of the electronic components are fully pressed.
Be careful not to fasten the cable too much that you can deform it.
Ensure that MC4 connectors do not come into contact with incompatible ones.
Voltages consent before any changes of the recovery of the electrical system.
High flexibility upon upgrade to MC4 1500V in utility projects.
Growing fame in DIY and RV off-grid no-plug solutions.
Amplification of the MC4 usage with the fuse or monitoring units oversees.
The sector's prevalent component use of the top international conformity patterns, order-wise.
Zion Communication supplies OEM and ODM services for MC4 connectors with ready-to-use products, your brand printing, other lengths of cable, pre-terminated connectors, and packaging.
