Wiring
Solar and power cables
We supply solar DC cable for the wiring between panels and the DCDB, and AC power cable for the run between the inverter, the ACDB and the load or grid connection.
What we supply
- Solar DC cable, single core, for string and array wiring
- AC power cable, single and multi core, for inverter and load connections
- UV and weather-resistant insulation for outdoor runs
- Sizes matched to your string current and cable run length
- Coils for stock or cut lengths sized to a project bill of materials
Choosing a size
Cable size depends on the current it carries and the length of the run, since a longer run loses more voltage for a given size. Tell us your string or load current, the DC or AC voltage, and the approximate run length, and we will recommend a cable size before you order.
| DC solar cable | Single core, UV-resistant, sized to string current |
|---|---|
| AC power cable | Single or multi core, sized to inverter or load current |
| Supply format | Coils or cut lengths for a project bill of materials |
Where it is used
Panel to DCDB wiring, inverter to ACDB wiring, and general power runs to the load or grid connection point on rooftop and ground-mount solar installations.
Frequently asked questions
Do you supply cable by the coil or by the metre?
Both. We supply standard coils and can also cut lengths to match a specific project bill of materials.
How do I know what cable size I need?
Send your string or load current, the system voltage and the approximate cable run length. We will recommend a size before you order.
