Grid connected PV inverters are required to have passive islanding detection and protection methods that cause the PV inverter to stop supplying power to the utility grid if the voltage amplitude or the frequency of the point of common coupling (PCC) between the local customer load and the utility grid strays outside of prescribed limits.

[FAQS about Three-phase inverter island protection]
Transistor T1 is wired as a current sensor, where the resistor R1 forms the current to voltage converter. The battery voltage has to pass through R1 before reaching the load at the output and therefore the current passing through it is proportionately transformed into voltage. .
Low Battery Cut-off Threshold The low battery sensing is handled by R3 and P1 which forms a potential divider to set the base voltage of the relay driver transistor (T2). When the. .
In the above paragraphs I have explained a very simple concept of inverter overload cut-off using only transistors. However a cut off systemusing only transistors cannot be very accurate and. The low voltage relay will automatically disconnect the DC power between the batteries and inverter, and/or other DC devices like lights or water heating elements. When the relay disconnects, the inverter will shut down and prevent further draw on the battery or batteries. [pdf]

Overloading occurs when the DC power from the solar panels exceeds the inverter’s maximum input rating, causing the inverter to either reduce input power or restrict its AC output. This can result in lost energy production, reduced efficiency, and even permanent damage to the inverter. [pdf]
