AJB — Array Junction Box

Array Junction Boxes (AJB) are used in larger solar arrays to combine multiple panel strings into a consolidated output before onward connection to the DCDB or inverter, reducing cable runs and simplifying array-level fault isolation.

• Multiple string inputs combined into a single output
• Weatherproof enclosure for outdoor array installation
• Simplifies fault isolation at the array level
• Manufactured in various input configurations to match array size
