When using the HP-AHP20SA series with generators, consider these troubleshooting steps and safety considerations:

Generator Type: Prefer inverter generators over non-inverter ones for consistent charging current and power stability. Non-inverter generators may not reliably reach the rated power.

Pre-Use Testing for Oil Generators: Conduct on-site no-load trials with oil generators due to their complex output conditions. Ensure voltage and frequency fluctuations remain within the HP-AHP20SA's tolerable range to prevent operational issues.

Regular Maintenance: Perform biannual maintenance checks. Ensure clear airflow, inspect for cable damage, check LED/LCD for error indications, tighten terminal screws, clean dirt and check for insect nests or corrosion, and ensure the lightning arrester is in good condition.

Utility Faults Handling: For AC over voltage, over current, under voltage, pre-charge timeout, relay adhesion, or frequency errors, disconnect AC input, turn off the inverter/charger, and wait 5 minutes before restarting. If issues persist, contact technical support.
