5. TROUBLE SHOOTING
Sunverter B Solar Pumping Inverters have complete protections. When a fault occurs,
the inverter will take protection actions: the general protection is to instantly stop the
output of the motor driving signal (shut down) and prohibit restarting for a period of
time. When the fault or protection occurs, the inverter will enter the fault display state,
and the operation panel will display blinking fault code. After the fault or protection is
cleared, the inverter will automatically carry out delayed restart. If the fault or protection
occurs repeatedly for a certain number of times, the inverter will stay in the fault display
state and not restart automatically anymore.
Users can press
reset, please contact a Dayliff retailer.

requirements. If there is no abnormality in the input power supply, the inverter internal
circuit should be faulty. Please contact Dayliff for help.
