Why do input terminals of inverters melt during use?

Inverters often encounter the problem of input wire terminal melting due to high temperatures during use. This is because the input terminals and connecting wires are not properly tightened or the terminals have rusted and aged, resulting in poor electrical contact and insufficient contact area. The excessive current passing through the terminals during operation generates heat, leading to high temperatures and eventual melting.

The relationship between power, voltage, and current is governed by the law of energy conservation: Power = Voltage * Current. According to this principle, to generate the same power, a lower voltage requires a higher current, necessitating the use of thicker connecting wires. Therefore, it is common for input connecting wires to become heated during the use of an inverter. The solution to this issue is to replace the connecting wires with thicker ones.

If you experience the problem of input terminal overheating and melting while using a GIANDEL inverter, there is no need to worry, as GIANDEL uses flame-retardant materials that do not cause fires. Please immediately disconnect the connecting wires and contact GIANDEL customer service, and we will provide you with better remedial advice suited to your specific situation."
