25mm2 2-core 1750m rolls 360 kg each Aluminium Cable

Aluminium 2 core twisted pair 25mm2/conductor comes in 1750 rolls.  Perfect for long run hydro and wind application at 120/48vdc applications for both off-grid and grid-tied applications.  To lay directly on the ground or buried in the ground for applications up to 120 vdc. This cable is the best buy for long runs and serious power generation.

If you double the cable length half the output power.
To half the % loss double the cable.

Each 1750m run can deliver the following Watts at about 10% loss

• 48vdc (56 nominal) 65W
• 120vdc (120 nominal) long 300 W

(To reduce to 5% loss you will need to run 2 lengths of this cable)

Use this cable for grid backup lines at up to 1750m away. Using a Outback MPPT FlexMax 60 you can deliver up to 300W at backup 24/7 to your RE system, avoiding the need for a generator set or attach to your hydro turbine 1750m away.

 As a rule of thumb for 8-10% loss for long runs using this cable:
Size in mm2 approx = current in cable (amps) x length (m) / 100
Divide this by 0.6 for aluminium wire

So for example 1700W at 56 vdc at 125m long is 1700/56 = 30.4 amps

Cable size = 30.4 x 125 / (100) = 38 mm2 copper or 63mm2 aluminium
