Choosing the correct DC Solar Cable for your photovoltaic system at home or at work is critical for both performance and safety. Australian cable are designed to carry solar energy from one system component to another so that it can be transformed into electricity. Your standard copper lines would do the job fine, but you'd almost certainly have a system failure.
How do I choose a PV cable?
So, before you install your system and turn it on, double-check that the size of the solar cable you use is proportionate to the system's current and voltage. Before you turn on the system, look for the following characteristics:
Make that the cable's voltage rating is equal to or higher than the system's voltage rating.
Ensure that the cable's current carrying capacity is equal to or greater than the system's current carrying capacity.
Make sure the cable wires are robust and well-protected to resist the weather conditions in your area.
To be on the safe side, check the voltage drop as well.
Let's take a look at each feature to be sure you have the proper Australian Cable for your system. So here's how it works:
Which cable is best for solar system?
Voltage
The voltage of your system will determine whether you use a thin or thick solar cable. Because the DC current drops as the system voltage rises, the cable must be thinner. To enhance the system voltage, choose a large inverter.
Current
Before purchasing solar wires and cables, make sure to check the current ratings. Australian cable manufacturers, such as znergy cables, has provided tables that list the current ratings of the cable-wire they've produced based on size and kind. Make sure you buy the proper size cables because undersized wires can quickly overheat and cause a substantial voltage drop, resulting in power loss.
Length
When it comes to picking the correct cable for your solar system, the length of the cable is also an important issue to consider. The longer the wires are, the better the current transfer is in most circumstances. However, based on the current capacity of the system, it is better to utilise a simple rule of thumb to calculate the required wire length. Cable size in mm2 = current / 3 You may simply find the closest precise and optimal cable size for your system with this method and avoid any mishaps or system failures by using it. How do you increase solar power output? Finding the correct solar cable for your system can be difficult, which is why, if you are new to the solar energy industry, you should always seek advice from an expert like Australian Cable Manufacturers. Additionally, always get cables and wires from reputable brands such as Znergy Cables.
