Generator Selection: Choose a generator compatible with the HP-AHP20SA series. Preferably, use an inverter generator as they provide more stable power and frequency output compared to non-inverter types. Oil generators with complex outputs require no-load trial testing to ensure voltage and frequency compatibility.

Generator Sizing: Ensure the generator is appropriately sized for the inverter/charger's power demands. A generator too small might need adjustments in the HP-AHP20SA series settings to prevent overloading.

Operational Considerations: Be patient during synchronization, as the inverter/charger might take time to align with the generator's output. Use a stabilizing load if necessary to smooth out initial fluctuations in voltage or frequency.

Software Settings: Adjust the HP-AHP20SA's settings if needed, especially if the generator is struggling to synchronize or maintain a stable output. This might include altering voltage or frequency limits to accommodate the generator's capabilities.

Safety Measures: Ensure proper ventilation and airflow for the generator, particularly during heavy use cases like battery charging. Be aware of the generator's operational limits, including duty cycle and rest periods.
