• Inverter emits warning beeps or alarms.
• Appliances connected to the inverter may not function properly or may stop working altogether.

Causes:

• Connecting too many appliances or devices with high power requirements to the inverter.
• Sudden spikes in power demand from certain appliances, such as refrigerators or air conditioners, during startup.
• Exceeding the maximum continuous power rating of the inverter.

Solutions:

1. Reduce Load: Disconnect some appliances or devices from the inverter to reduce the overall power demand. Prioritize essential appliances and avoid running multiple high-power devices simultaneously.
2. Upgrade Inverter: If overloading is a recurring issue, consider upgrading to a higher-capacity inverter that can handle the power requirements of all connected appliances.
3. Use Power Strips: Use power strips or surge protectors with built-in circuit breakers to limit the power draw from individual outlets. This can help prevent overloading by automatically shutting off power to specific outlets if the load exceeds a certain threshold.
4. Distribute Load Evenly: Spread out the power load evenly across multiple outlets or circuits to avoid overloading any single outlet or circuit.
5. Check Appliance Ratings: Ensure that the power ratings of all connected appliances and devices are within the capacity of the inverter. Avoid connecting appliances with higher power requirements than the inverter can handle.

Preventive Measures:

• Regularly check the power ratings of connected appliances and ensure they are compatible with the inverter’s capacity.
