Cable Sizing Estimation- DC Systems

The correct size of cable is essential to get the most out of any low voltage energy system. An under-sized cable can cause major issues with voltage drops and in extreme cases it can be very dangerous.

Our online calculator makes it easy to select the correct size cables for use in your low voltage DC power system.

This calculator is provided for estimation purposes only; Solosol recommends that all cables are installed and sized in accordance with the cable and equipment manufacturers recommendations and local regulations.

To use the calculator :

1 - Enter percentage cable loss acceptable [normally approx 2 or 3%].

2 - Select system voltage.

3 - Enter max amps to be carried by the cable [amps = watts / voltage].

4 - Enter max length of cable run required.

5 - Click "Calculate"
