This article explains the blink codes of the status LEDs of Fischer Panda PMGi inverters.
You can use the additional start function “inverter softstart” to avoid problems when starting large electrical loads. If this function is activated, the inverter carries out measures at start-up to limit the power when switching on the loads (softstart).
In order to check whether the inverter causes a fault, it is often a first test to start the generator without an inverter. The function “Start without inverter” (start w/o inverter) is an additional start function for this use case. It simulates the engine revolution so that the generator can be started without inverter in case of service.
