Solar connector QOLTEC MC4 Type Y 1000V 30A – Y-branch for photovoltaic panels

QOLTEC MC4 Type Y 1000V 30A is a Y‑branch solar connector designed for photovoltaic panels and arrays. Rated for up to 1000 V and 30 A, this MC4 Type Y connector enables the parallel connection of two solar panel strings into a single output while remaining compatible with standard MC4 systems. The connector is built for outdoor photovoltaic use and provides secure, weather‑resistant electrical contacts to simplify wiring and reduce installation time.

Advantages

The QOLTEC MC4 Type Y connector enables combining two panel strings without altering existing MC4 cabling, maintaining compatibility with standard MC4 male and female connectors. With a 1000 V voltage rating and 30 A current rating, it is suitable for many contemporary PV installations. The Y‑branch design reduces the number of junctions required, helps preserve correct polarity and provides reliable contact and weather resistance for outdoor conditions.

Suitable for

• Parallel connection of two solar panel strings
• Residential and small commercial photovoltaic arrays
• Off‑grid and hybrid solar systems
• Retrofit or expansion of existing MC4-based installations

How to use

Ensure panels and cabling are de‑energized before connecting. Match MC4 polarity and insert male and female MC4 ends until they click to secure contacts. Use the Y‑branch to join two positive strings into one positive output or two negative strings into one negative output—do not mix polarities. After assembly, verify mechanical retention of each connector and route cables to avoid strain, chafing or damage from sharp edges.

Usage recommendations

Confirm the combined current of the parallelled strings does not exceed 30 A and that system voltage remains within 1000 V. Use the connector only with compatible MC4 components, inspect seals and contacts periodically for outdoor exposure, and follow local electrical codes and safety practices when installing or modifying PV wiring.
