Which power cable for inverter?
The power cable for an inverter should be selected based on the power rating of the inverter, the distance between the inverter and the power source, and the current it will carry. Typically, for residential solar installations, cables with a cross section of 4 mm² to 10 mm² are used, but this can vary depending on the specifications of the inverter.
The cable must be capable of handling the maximum output current of the inverter and be rated for the appropriate voltage.
In addition, the insulation of the cable must be adapted to the environment in which it will be installed.
Which cable for inverter?
To power the inverter, you must use a cable that matches the current and voltage ratings of the inverter.
For example, if the inverter requires 10 A current and operates at 240 V, a cable rated for at least 10 A and 240 V should be used. In practice, cables are chosen with a certain margin above the expected load to guarantee safety and longevity. For solar systems, this often means using cables with sufficient cross section to handle the maximum current while minimizing voltage drop over the distance between the inverter and the power source.
For a current of 32A, the recommended cable section depends on the distance and the type of installation.
Generally, 6mm² cable is suitable for most installations where the distance is relatively short and the cable is installed in a controlled environment.
For longer distances or installations subject to high temperatures, a larger cable may be required to reduce voltage drop and ensure safe operation.
What cable to use for an inverter?
For a power rating of 12 kW, the appropriate cable size depends on the current drawn and the distance from the power source.
Assuming a 230 V system, a 12 kW load would draw approximately 52 A (12,000 W ÷ 230 V). To handle this current, a cable with a cross section of 10 mm² to 16 mm² is commonly used, depending on the installation conditions and distance. The exact cable size should be confirmed based on specific installation standards and regulations.
For a nominal power of 30 kW, the cable section must be sized to support the high current and minimize the voltage drop. For a 400 V three-phase system, a 30 kW load would draw approximately 43 A.
Typically, a cable with a cross section of 16 mm² to 25 mm² is used for such applications, although the exact size may vary depending on the distance, installation environment and regulatory requirements.
Proper sizing ensures safe and efficient operation.
