PRECISION INEVERY CONNECTION.
Three current ratings, one 3-split platform. Every variant shares the same enclosures, sealing system and cable assemblies, and differs in diode selection and thermal design to match the short-circuit current of the module it serves.
25A
In productionSOMNYX SJB-1525
The 25 A variant is designed for mainstream crystalline-silicon modules whose short-circuit current, including any bifacial gain, sits comfortably below the box's rated current.
| Configuration | 3-split junction box |
|---|---|
| Maximum PV system voltage | 1500 V DC |
| Rated current | 25 A |
| Enclosure protection | IP68 |
| Bypass diodes | 3One per split box |
| PV cable cross-section | 4 mm² |
30A
In productionSOMNYX SJB-1530
The 30 A variant is designed for higher-current large-format modules, giving additional margin for bifacial rear-side gain and elevated operating temperatures.
| Configuration | 3-split junction box |
|---|---|
| Maximum PV system voltage | 1500 V DC |
| Rated current | 30 A |
| Enclosure protection | IP68 |
| Bypass diodes | 3One per split box |
| PV cable cross-section | 4 mm² |
35A
In productionSOMNYX SJB-1535
The 35 A variant is designed for the highest-current module formats, with diode selection and heat dissipation across the three split boxes sized for maximum thermal margin.
| Configuration | 3-split junction box |
|---|---|
| Maximum PV system voltage | 1500 V DC |
| Rated current | 35 A |
| Enclosure protection | IP68 |
| Bypass diodes | 3One per split box |
| PV cable cross-section | 4 mm² |
