The role of the diode in the photovoltaic combiner box
The diode in the module junction box is mainly to provide a continuation channel when the cell is blocked, while the diode in the convergence box is mainly to prevent loop current between strings.

Combiner boxes play an important role in photovoltaic (PV) installations. This comprehensive guide aims to shed light on the importance, functions, types and best practices of combiner boxes, unlocking the mystery behind their role in harnessing solar energy.
The role of the combiner box is to bring the output of several solar strings together. Daniel Sherwood, director of product management at SolarBOS, explained that each string conductor lands on a fuse terminal and the output of the fused inputs are combined onto a single conductor that connects the box to the inverter.
In the convergence box, the role of diode and component junction box diode is different. The diode in the module junction box is mainly to provide a continuation channel when the cell is blocked, while the diode in the convergence box is mainly to prevent loop current between strings.
DC combiner boxes play a crucial role in PV systems, typically located between the solar panels and the inverters. The primary task of these combiner boxes is to consolidate and series-connect direct currents generated by solar panels into a higher voltage direct current circuit.
