Yes. A dedicated generator input gives the inverter an additional source for backup and battery charging when grid supply is unavailable or solar production is low. SRNE lists maximum grid/generator charging current of 100A for the 8kW model and 120A for the 12kW model. In practice, generator capacity should be matched to the expected load and charging demand, and the generator voltage and frequency must remain within the inverter's accepted input range. Generator sizing should also leave enough margin for simultaneous load supply and battery charging.
