If the power demand exceeds the inverter’s rated capacity, the system may experience issues such as overheating, shutdowns, or even permanent damage to the inverter. Inverter capacity overload happens when the electrical load (the total amount of power drawn by connected appliances) exceeds the power rating of the inverter.
Oversizing your solar system generally means that your solar inverter is oversized for the amount of solar panels and energy output you currently have. An example of this would be if you have 4kW of solar panels but a 5kW solar inverter. Why would I oversize my solar inverter?
Inverter capacity overload is one of the most common issues in solar energy systems. It occurs when the power demand from connected appliances exceeds the inverter’s maximum rated capacity. This can lead to inefficiencies, inverter failures, and potential damage to the inverter or other components.
Overloading the inverter may improve the weighted efficiency of the Solar Inverter, leading to better yield. For most of the inverters, the efficiency of the solar inverter is relatively low when inverters are underloaded. Sample efficiency Curve of SMA Inverter for reference.
