Can a DC inverter be overloaded?
So I can overload the inverter when there is enough power on the DC input side. When there is not enough power on the DC input side (and there is no grid), then the inverter shuts down with overload. Without grid the inverter always tries to deliver the power needed by the loads. There is no way to limit the output power.
What happens if you oversize an inverter?
Excessive oversizing can negatively affect the inverter’s power production. Inverters are designed to generate AC output power up to a defined maximum which cannot be exceeded. The inverter limits or clips the power output when the actual produced DC power is higher than the inverter’s allowed maximum output. This results in a loss of energy.
What happens if a solar inverter exceeds a power rating?
Exceeding this power rating can lead to overloading the inverter and potential system malfunctions or damage. To avoid overloading your solar inverter, ensure that the total power output of your solar panels does not exceed the inverter’s capacity.
Do PV inverters oversize?
PV inverters are designed so that the generated module output power does not exceed the rated maximum inverter AC power. Oversizing implies having more DC power than AC power. This increases power output in low light conditions. You can install a smaller inverter for a given DC array size, or you can install more PV modules for a given inverter.
Is there a way to limit the output power of an inverter?
Without grid the inverter always tries to deliver the power needed by the loads. There is no way to limit the output power. You have AC Out 2 and (depending on the exact model you have) at last one relay that you can use to switch off loads in case of overload. "I expected that the grid would kick in as soon as I am over the inverter's max load."
How do I avoid overloading my solar inverter?
To avoid overloading your solar inverter, ensure that the total power output of your solar panels does not exceed the inverter’s capacity. This can be determined by calculating the maximum power output of your panels under normal operating conditions and comparing it to the inverter’s power rating.

Inverter clipping: How to maximize solar project value
Inverter clipping, or "inverter saturation," occurs when DC power from a PV array exceeds an inverter''s maximum input rating. The inverter may adjust the DC voltage to reduce input power, increasing voltage and reducing DC current. Alternatively, the inverter may restrict or throttle the inverter''s AC output.
TECHNICAL NOTE
Due to the common Maximum Power Point (MPP) characteristics of the inverter input, the inverter will not be able to find the optimal power point if the current is outside of the specified range. In that case, losses in energy yield can occur. However, the inverter will not be affected if the short
