  ※  The inverter cannot start or starts with difficulty

   ◆   Battery voltage is too low

   ◆   Poor contact of input power line

   ◆   Inverter internal fuse is blown

  ※  Unstable or abnormal output voltage

   ◆   Unstable input voltage

   ◆   Inverter internal circuit board failure

   ◆   Inverter load is too large

  ※  Inverter overheating alarm

   ◆   Too much dust on the radiator

   ◆   Ambient temperature is too high

   ◆   Inverter runs at full load for a long time

  ※  Other common faults

   ◆   Protection circuit action

        If the load is normal, check whether there is a short circuit in the inverter internal circuit.

   ◆   No display on the display

        If the connection line is normal, it may be that the display itself is faulty and a new display needs to be replaced.

   ◆   Inverter frequently restarts

        Try to restore the factory settings to see if the problem can be solved. If the problem still exists, contact a professional maintenance personnel for inspection.

  ※  Daily maintenance suggestions

  ●  Regularly clean the dust inside the inverter and keep ventilation and heat dissipation.

  ●  Avoid the inverter running at full load for a long time and arrange the use time reasonably.

  ●  Regularly check the battery voltage and battery connection to ensure normal battery power supply.

  ●  Check if the inverter input power line is loose or damaged, and make sure it is well connected.

  ●  Avoid placing the inverter in a hot and humid environment, and choose a cool and ventilated place to place it.

Through the above steps, you can troubleshoot and maintain the KEWO solar pump inverter to ensure its normal operation and improve the service life and efficiency of the equipment. If the problem still cannot be solved, it is recommended to contact KEWO's official after-sales or professional maintenance personnel for further inspection and repair.
