  If your Shenzhen Pulansi Technology Inverter is beeping continuously and the red LED is illuminated, the possible causes include: output short circuit (check wiring and remove abnormal load), fan fault (replace the fan), weak battery (recharge or replace the battery), over-charged battery, high battery voltage (check battery specifications and quantity), overload error (reduce connected load), high internal temperature (check airflow and ambient temperature), output voltage too high or low, or main relay stick (return to repair center).

  Rodney SmithAug 15, 2025
  If your Shenzhen Pulansi Technology Inverter is operating in battery mode despite the presence of mains power, it could be due to a tripped input fuse (check the AC fuse and wiring) or insufficient AC power quality. If the AC power quality is insufficient, check if the AC wires are too thin or long, or if a generator is in use, ensure it's working correctly and the input voltage range setting is correct.

  If there is no LED display on the front panel of your Shenzhen Pulansi Technology Inverter when the utility power is normal, check if the battery is connected well by inspecting the external battery cable and terminal. Make sure all the battery connections to the unit are correct. If the connections are correct, the battery may be defective and needs replacement.
