Solar DCDB

DCDB stands for Direct Current Distribution box and is installed between the solar panels and the inverter. This box protects your solar inverter and panels from high voltage and short circuits.

A DCDB box contains a DC SPD to protect against surges, a DC MCB, and a fuse that breaks the circuit in case of high voltages.
DCDB boxes are made using waterproof and dust-resistant material which makes them secure and durable. While purchasing these junction boxes, one has to make sure that the product comes with a weatherproof IP65 casing.
