For a clothes washer and dryer, you typically don't need an inverter. Inverters are electronic devices that convert direct current (DC) to alternating current (AC). They are commonly used to power AC appliances and electronics when you have a DC power source, such as solar panels or batteries.
Washing machines and dryers used in homes are designed to be directly connected to a standard AC power supply, typically 120V or 240V depending on the country's electrical system. These appliances operate on AC power, so you can plug them directly into a regular power outlet.
However, if you are considering using a washer or dryer in an off-grid scenario, where you only have access to DC power from batteries or solar panels, then you might need to use an inverter to convert the DC power to AC power. In such cases, you would choose an inverter with a sufficient power rating to handle the peak power requirements of the washer or dryer.
In summary, for normal household use, you do not need an inverter for your clothes washer and dryer, as they are designed to work with standard AC power supplies. But if you are using them in an off-grid setting, you would need an inverter to power them with DC electricity.
