The selection of appropriate electrical wires is crucial for electrical safety. Properly chosen wires ensure efficient power transmission, minimize energy loss, and reduce the risk of electrical accidents such as fires, short circuits, and electrocution. Selecting the right gauge, insulation material, and wire type is essential for maintaining electrical system integrity and preventing damage to appliances and equipment. Inadequate wiring may lead to overloading, overheating, and potential hazards. Always adhere to local electrical codes and consult a professional electrician for guidance in choosing the right electrical wires.
When selecting the size of the connecting wire, it is important to consider the following factors:
Based on the power and voltage (which can be found in the inverter's label), the current of the circuit can be calculated.
<aside> 📌 Power / Voltage = Current
Assuming the output voltage of the current inverter is 230V and its rated power is 5kW, then the circuit current can be calculated as 230V/5kW=46A. We can choose the wire according to 46A.

Then you need to estimate the length of the circuit. The longer the circuit, the greater the voltage drop caused.Copper has better conductivity than aluminum, and under the same conditions, copper wires have a smaller diameter. Please choose according to the actual situation.
