If your Sharp Inverter shows error code 'E-23', it indicates that the internal temperature of the power conditioner is too high. Turn the power off and allow the unit to cool down. Also, review the location of your Inverter to ensure proper ventilation.
What to do if my Sharp Inverter displays error 'D-47'?
If your Sharp Inverter displays 'D-47', check the fuse. If the fuse is open, replace it by inserting a new fuse into the fuse socket.
What to do if my Sharp Inverter shows 'F-01 GRID OFF'?
If your Sharp Inverter displays 'F-01 GRID OFF', it indicates a power failure. First, wait for the utility company to restore power after the blackout. If the AC Disconnect Switch is off, turn it on. Also, check if the dedicated breaker of the distribution board is off and turn it on if necessary. Finally, ensure that the grid voltage between L1 and L2 is above 240V.
How to troubleshoot a Sharp Inverter with no display?
If your Sharp Inverter display is not working, follow these steps: 1. Ensure the DC disconnect switch is in the ON position. 2. Verify that there is sufficient sunlight. 3. Check the PV module for any issues related to sunlight reception. 4. Inspect the wiring of both the PV module and the power conditioner.
Why does my Sharp JH-3500U Inverter display 'STOP'?
