Multi-String Parallel System: Prevents current loss between strings, especially suitable for sites with uneven shading.

PV Panel Optimization: Provides independent diode protection for individual panels, replacing the diodes in traditional junction boxes.

Frequently Asked Questions

QWhy does my solar system need MC4 anti-reverse diode connectors?

A:When a component in the photovoltaic array is blocked, the current generated by other components will flow back into the component, causing heat or even fire. Anti-reverse diodes can conduct in one direction, completely eliminating such risks.
