Solar Combiner Boxes
Safely combine multiple solar strings with combiner boxes from PES Supply. Combiner boxes consolidate the output of several panel strings into a single feed to the inverter, providing per-string overcurrent protection and a single disconnect point. Shop trusted brands including Midnite Solar, OutBack Power, Schneider Electric, Eaton, and more.
Combiner Box Features
- String-level fusing with DC breakers or fuse holders
- Surge protection (SPD) integrated or optional
- NEMA 3R and 4X weatherproof enclosures
- Disconnect capability for safe inverter service
- Multiple string inputs (2 to 24+ strings)
- Rapid shutdown integration options
Combiner boxes are required for most multi-string solar arrays per NEC 690. They simplify wiring, protect each string individually, and provide a single point for lockout/tagout during maintenance. Choose a box rated for your system voltage (150V, 600V, or 1000V) and number of strings.
