Does a photovoltaic DC combiner box need a reverse protection diode

To ensure safety in the current collection process, the combiner box must be equipped with various electrical protection devices, such as anti-reverse diodes, overcurrent protection, and lightning protection devices. Let's talk about the specific configuration of anti-reverse diodes to prevent these costly reversals. To configure anti-reverse diodes correctly in a DC combiner box 1, you must size the diode's current rating to at least 2x the string's Short Circuit Current (Isc) 2 and ensure the Reverse. The combiner box is an indispensable part of the photovoltaic power station, and the anti-reverse diode is an indispensable part of the combiner box, so how to choose the anti-reverse diode is a very important link for not only the combiner box but also the photovoltaic power station.
