A Direct Current Distribution Box (DCDB), also known as an Array Junction Box (AJB), is a critical component in a solar power system. It is installed between the solar panels and the inverter to manage and protect the direct current (DC) generated by the solar panels.
The DCDB combines the output of multiple solar panel strings into a single feed, providing surge protection and circuit isolation to safeguard the inverter and panels from high voltage or short circuits.
Essential benefits for your solar power system
Protects solar panels and inverters from overcurrent, voltage surges, and short circuits using DC fuses, MCBs, and SPDs.
Combines multiple DC inputs from solar panel strings into a single output for the inverter.
Ensures safe operation by isolating faulty circuits and preventing damage to expensive equipment.
Some DCDBs include monitoring systems to track DC performance and optimize energy production.
Solutions for every scale of solar installation
Suitable for small systems (1-5 kW) with one string and one Maximum Power Point Tracker (MPPT).
Used for systems (5-10 kW) with two MPPTs and up to 10 PV modules per string.
For larger systems with multiple strings and higher DC input.
Used in commercial setups with extensive panel arrays.
Tailored for specific project requirements, available in 500V or 1000V ratings.
