Solar DCDB Boxes
DC Distribution / string combiner boxes that bring together multiple PV strings, fuse-protect each one, and clamp transient surges before the array's DC output reaches the inverter.

Construction
IP65 enclosure with per-string fuse holders, a DC load-break isolator for safe maintenance disconnection, and a surge protection device sized to the array's DC voltage class. String count is configured to match your array design.
Suitable for rooftop and ground-mount installations where multiple PV strings need to be combined before the inverter.
What is a Solar DCDB or string combiner box?
A Solar DCDB (DC Distribution Box) combines multiple PV strings into one output, fuse-protects each string individually, and clamps transient surges before the array's DC output reaches the inverter.
How many PV strings can one DCDB handle?
Our standard DCDBs support 2 to 24-way string inputs. String count is configured to match your array design, with per-string fuse holders for each input.
Is a DC isolator included in the DCDB?
Yes, each DCDB includes a DC load-break isolator for safe maintenance disconnection, along with a Type II DC surge protection device sized to the array's voltage class.
Do you supply Solar DCDB boxes across South India?
Yes. We dispatch Solar DCDB boxes from Hyderabad across Telangana, Andhra Pradesh, Karnataka, Tamil Nadu and Kerala, with PAN-India delivery available for larger orders.
