Panel-to-panel connections, linking multiple solar panels in series
Panel to combiner box, caries DC power from panel strings to a central junction box
Combiner box to inverter(DC side) transmits the collected DC power to the inverter before conversion to AC
Apply cable base on its insulation property
Avoid bends
Always de-energize the system before working on cables
Proper PPE duing operation
| Considerable Feature | Why It Matters |
| UV Resistance | Outdoor installation requires protection from sun. |
| Halogen-Free / Low Smoke | Safer in case of fire. |
| Tinned Copper Conductor | Corrosion resistance, especially in humid areas. |
| XLPE / EPR Insulation | High thermal and electrical resistance. |
| Double Insulation | Enhanced durability and mechanical protection. |
| Flexible (Stranded Core) | For easy routing on rooftops or in tight areas. |
