Yes, the issue you are experiencing with your inverter turning off when an appliance is plugged in is likely due to the voltage output of the inverter not meeting the requirements of the appliance. Here's why this might be happening:
Voltage Output: As you mentioned, the inverter is showing an output voltage of about 215V, while most appliances require a standard voltage of +220V or higher, depending on your region's power standards. If the voltage output of the inverter is consistently below what the appliance needs, the inverter may detect a problem and shut off to protect itself and the connected appliance.
Underload/Overload Protection: Inverters usually have built-in safety mechanisms to protect against underload or overload conditions. An underload condition occurs when the connected appliance requires more power than the inverter can supply, and an overload condition happens when the connected appliance draws more power than the inverter's capacity. In either situation, the inverter might shut off to avoid damage to the appliance or the inverter itself.
Voltage Regulation: High-quality inverters typically have better voltage regulation, meaning they can maintain a stable output voltage close to the desired value (e.g., 220V). Cheaper or lower-quality inverters may have more significant fluctuations in their output voltage, leading to compatibility issues with certain appliances.
To resolve this issue, you have a few options:
Check Appliance Requirements: Verify the power requirements of the appliance you are trying to use and ensure it matches or is within the acceptable range of your inverter's output voltage. If the appliance requires a higher voltage, consider using a different power source or a compatible voltage regulator.
Use a Voltage Regulator/Stabilizer: If the voltage difference is not significant, you can use a voltage regulator or stabilizer between the inverter and the appliance to maintain a stable voltage at the required level.
Upgrade the Inverter: If the voltage output of your current inverter cannot meet the needs of your appliances, consider upgrading to a higher-quality inverter with better voltage regulation and higher capacity.
Consult a Professional: If you're unsure about the technical aspects or how to resolve the issue, it's best to seek help from a qualified electrician or technician who can assess your setup and recommend appropriate solutions.
Remember, using an inverter with the correct voltage output and proper safety features is essential for protecting your appliances and ensuring their longevity.
