Description
500V OFF-Grid Solar DCDB Box with MCB, Fuse & Surge Protection
The Solar DC Distribution Box (DCDB) 500V OFF-Grid is a reliable protection and distribution solution designed for off-grid solar power systems. It safely manages DC power flow from solar panels to the inverter while providing protection against overloads, short circuits, and voltage surges.
This DCDB unit comes pre-installed with essential protection components such as DC MCBs, DC fuses, and Surge Protection Devices (SPD) housed inside a durable transparent enclosure for easy inspection and maintenance. The weather-resistant enclosure helps protect internal components from dust and moisture, making it suitable for indoor and semi-outdoor solar installations.
Designed for solar PV applications, the DCDB improves overall system safety, reliability, and maintenance convenience in residential, commercial, and industrial solar setups.
