6 FAQs about The rated power of the inverter exceeds the power of the appliance

What is a solar inverter AC overload?

An inverter AC overload occurs when the power on the AC output exceeds the inverter's nominal power to supply electricity. In fact, solar inverters can handle a certain range of AC overloads for a short period, where the inverter is subjected to a power demand spike that exceeds its rated capacity.

What happens if a power inverter is over rated?

When the total power of the appliances you connect exceeds the rated power of the inverter, the inverter triggers protection to automatically cut off power because of the power excess. The inverter case gets hot, the connecting wires or terminals melt and burn due to the excessive current. This overload is common in the following scenarios:

Should I upgrade my inverter to a higher-capacity model?

If the power demand consistently exceeds the inverter's capacity, consider upgrading to a higher-capacity model. Ensure the new inverter can handle the total load of all connected devices. Circuit breakers can protect against overloads by automatically cutting off power when the load exceeds a certain threshold.

What if the connected load power does not exceed rated power?

If the connected load power does not exceed the rated power of the inverter, check if the connected loads are inductive loads and whether their inrush power exceeds the inverter's surge capacity. You can try connecting connecting them one by one, and once the system's power supply is stable, connect the remaining loads.

What happens if an inverter overloads?

If the total load exceeds this value, the inverter will be damaged due to constant overloading. What is Peak Power? Peak Power, also known as Surge Power, represents the maximum power value that the inverter can deliver in a short period (usually 0.5~5 seconds).

Does AC side overloading damage the inverter?

Another scenario is that AC side overloading does not damage the inverter, which is common in on-grid inverters. For example, the SOLXPOW energy storage inverter supports not only a brief overload of twice the rated power but also a continuous AC overload of 1.1 times the rated power.
