MOREDAY MC4 Connector with Diode
Solar mc4 connectors with diode are available in 10A, 15A and 20A. Compatible with MC4 photovoltaic fuses. Easy and quick to install, suitable for harsh outdoor environments. Diodes pass current in one direction, so current from the solar panel flows toward the battery (forward bias) and prevents flow from the battery to the solar panel (reverse bias), preventing the solar panel current from flowing backwards and causing a hazard.
Key Characteristics
Secure Connection
The connector’s secure locking mechanism guarantees a safe and stable electrical connection, reducing the risk of disconnection or power loss.
The diode provides the functions of rectifier circuit, detection circuit and voltage stabilizing circuit. It only allows one-way current to pass through and blocks the reverse direction.

popular questions
FAQ`s.
1. What is an MC4 connector with diode used for?
The MC4 connector with a diode is used in solar installations to prevent reverse current flow, which can occur when one or more solar panels are shaded. The diode helps maintain system efficiency by allowing electricity to flow in one direction while blocking any backflow.
2. How does the diode in the MC4 connector improve solar panel performance?
The diode prevents the solar panel from acting as a load when it's shaded, which can otherwise reduce the overall system performance. This protection ensures that even if part of a solar array is shaded, the remaining panels can continue operating efficiently.
3. Are your MC4 connectors with diode weather-resistant?
Yes, our MC4 connectors with diode are designed to be weather-resistant. They are built to withstand extreme temperatures, moisture, and UV exposure, ensuring reliable performance in various outdoor environments.
4. How can I ensure that the MC4 connectors with diode I purchase are genuine and of high quality?
You can ensure the authenticity and quality of our MC4 connectors with diode by purchasing directly from us or authorized distributors. Our products are CE and TÜV certified, which guarantees their safety and reliability.
5. What should I consider when choosing an MC4 connector with diode for my solar project?
When selecting an MC4 connector with a diode, consider factors such as the quality of materials, compatibility with your solar panels, certification standards, and the manufacturer's reputation. Our connectors are manufactured to the highest standards, ensuring optimal performance and compatibility.
