What Is a PV Diode Connector?

A PV diode connector is a connection component designed for photovoltaic systems where a diode is incorporated into or connected with the PV electrical circuit. The diode can be used to control current flow or provide a specific electrical function within the photovoltaic system.

The required diode type and electrical rating depend on the design of the PV module and system. The connector and diode specifications should therefore be matched to the intended application.

PV Bypass Diode Application

D4B can be used as a connection solution for bypass diode applications in photovoltaic modules. A bypass diode provides an alternative current path under specific operating conditions and can help reduce the electrical impact of partial shading on a PV module or cell group.

The diode rating and configuration should be selected according to the PV module design, operating current, system voltage and applicable technical requirements.

Technical Data

1500V PV Application

D4B is rated for 1500V, making it suitable for photovoltaic applications designed around higher system voltages.

The connector’s electrical rating should be considered together with the PV module, cable, diode and other components used in the complete circuit. The final application should always remain within the applicable component ratings and installation requirements.

Outdoor Protection

D4B provides IP67 protection for outdoor photovoltaic applications and is specified for an ambient temperature range of -40°C to +85°C.

The outer housing is designed with resistance to UV exposure and aging, supporting the environmental conditions commonly encountered in outdoor solar PV installations.

Applications
