This status code indicates that the Fronius Primo GEN24 208-240 inverter has detected a violation of the local grid code, leading to a shutdown. This occurs when grid parameters (such as voltage or frequency) fall outside the permissible limits defined by the selected grid code, or if an incorrect grid code has been configured.

This status code indicates that the Fronius Primo GEN24 208-240 inverter has received an external shutdown command. This typically originates from an external control device, such as a ripple control receiver or utility command, or a wiring issue in the external control input.

This status code indicates that the Fronius Primo GEN24 208-240 inverter requires maintenance or has detected a non-critical internal issue that warrants attention. It may signify that a scheduled maintenance interval has been reached or that a minor internal fault has occurred which does not immediately stop operation.

This status code indicates that the inverter has stopped operating in backup power mode due to excessive electrical loads connected to the PV Point. The inverter has a maximum continuous output of 1560 W (120V at 13A) and an overload capacity of 35% for a duration of 5 seconds, depending on the current PV module power.

This message is displayed when the Primary meter function is deactivated, causing the inverter to switch to Standby mode. This occurs when there is insufficient PV power available and no energy management command is being sent to the battery, for instance, if the battery has reached its minimum state of charge.

The Fronius Primo GEN24 inverter detects a low DC isolation resistance (RISO) in the PV generator or associated wiring, leading to an error state and immediate shutdown of the system. This condition indicates a leakage current path from the DC conductors to ground, posing a safety risk and preventing normal operation. The threshold for this fault is an RISO value below 500 kOhm.

The automatic self-test for the Rapid Shutdown (RSD) function has failed. This self-test specifically monitors the discharge circuit of the RSD function and is performed during each startup procedure, prior to connection to the public grid, when DC voltage exceeds 40V.

The Rapid Shutdown (RSD) function was automatically activated due to the inverter detecting a loss of the grid connection. This event, typically an interruption by an AC breaker, causes the inverter to discharge the PV module terminals to less than 30 VDC and less than 15 VAC within 30 seconds.

The Rapid Shutdown (RSD) function has been manually initiated through the activation of an external Wired Shut Down (WSD) trigger device or switch. This action interrupts the communication from the inverter to compatible rapid shutdown devices on the PV modules, resulting in a discharge of module terminals to less than 30 VDC and less than 15 VAC within 30 seconds.
