This pre-wired solar PV combiner box takes 4 string inputs and 4 string outputs, rated to 600V DC. It brings multiple PV strings together into a single output while giving each string its own protection. A 600V DC breaker, string fuses, surge protection device and LED string indicators are all built in, so faults on any one string are easy to spot.

Key features

• Configuration, 4 string inputs / 4 string outputs, 600V DC rated
• Disconnection, 600V DC breaker for safe system isolation
• Overcurrent protection, individual string fuses on each string
• Surge protection, SPD fitted for lightning and voltage spike protection
• Fault indication, LED indicator per string
• Enclosure, waterproof, 373 x 302 x 132mm, pre-wired and ready to connect

Applications

Suited to off-grid and hybrid solar systems that combine several PV strings, where individual string fusing and quick fault identification matter. It works for both outdoor and indoor mounting thanks to the waterproof enclosure.

Installation notes

DC connections must be made by a qualified solar installer. Check string voltage and current against the box ratings before wiring in, and keep the maximum system voltage at or below 600V DC across any string.
