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
If your Sharp JH1600 inverter is stuck on a D21 fault the best thing to do is replace the faulty inverter with a quality 1.5kW solar power inverter. We recommend the Fronius Galvo 1.5 as a nearly bulletproof replacement unit with a long 10 year parts warranty that is perfectly sized to replace the Sharp JH1600.
Sharp d-21 Fault – What To Do
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.
As also mentioned in Sharp’s response the d-21 fault code is usually caused by lightning or a power surge from the power grid.
