By entering the settings, under the Gen port use menu, you will find the configuration options for the micro inverter input.
The generator is most often used in off-grid systems to charge the battery. This way, the otherwise noisy generator does not need to run continuously — it can recharge the battery in a short period of time, after which the system can operate from the stored energy.
Make sure that the input power does not exceed the rated power of the Deye inverter. In this configuration, only a three-phase generator can be connected to a three-phase inverter, and only a single-phase generator to a single-phase inverter.
