Sharp JH1600 inverter D-21 Fault Code? Not Good.

Sharp Inverter with d-21 error code

Have you just walked past your Sharp JH1600 solar inverter and been greeted with a d-21 fault on the screen?

Unfortunately the d-21 error is a major internal fault with the inverter and the official response from Sharp to this code is: “the d-21 fault is caused by excessive voltage transients on the input or output of the inverter.

It is highly likely that an external factor such as Lightning or Power surge on the Grid is the root cause of this issue. These type of faults may be covered by Domestic Home Insurance.”

d-21 Fault – Not Covered by Sharp’s Warranty

So you can pretty much read into this that it’s a fault that Sharp will not cover under warranty, they are blaming an external issue as the cause and are wiping their hands of any responsibility.
