I'm in AZ too and just had my 2nd one of these failures. Is your inverter inside or outside?

3 SolarEdge 18XB7 Failures

It’s outside right by the circuit breaker box. I hope we don’t have to get replacements every other year.

Mine is inside garage so I'm hoping that's better for whatever is causing this problem.

So about 3 weeks from opening the case with Tesla to getting a new unit installed?
Just had my 2 inverters replace, but up and running. Yea, just in time for the new Tesla tomorrow 
Tesla installed the new inverter and we are back in business. Happy with customer service and time frame

Same here. 3 1/2 weeks from failure to back online. Much better than the 2 1/2 months it took 19 months ago when the first one failed.

Wow. So happy you both had a quick turn around time.
Did they replace with same make and model inverters? Tesla isn’t using their own inverters to replace Solaredge are they?

No, as that would essentially require reinstalling the entire system. (Pulling the panels up and rewiring everything to remove the SE optimizers and installing the Tesla rapid shutdown devices.)

Didn’t think so, thanks for confirming. So sounds like Tesla and SolarEdge may have finally figured out how to do service timely.
Good chance there could be an issue with tesla not wiring properly or you are undersize. What is the capacity of your inverter and solar panels? I have a 7.6 setapp solaredge with 10.4kw system.
Looks like my inverter failed after about just 2 years. Spike in output at dawn and then 0 power generation. Reset = 0.
Looks like these inverters are not very reliable and subject to early/frequent failures. Tesla closed until Monday. If these failures are recurrent as reported above it makes having roof top solar uneconomical.

Inverter failures happen; nothing is perfect. Call Tesla Monday, get an appointment for a replacement, if that's what is diagnosed, and keep calling them to manage the process.
As they are supposed to have a ten year plus lifespan, I think a little perspective is warranted. You aren't buying a new inverter now. When the inverter fails out of warranty, then yes, you are out of pocket. When I ran my ROI calculations for solar ROI, I built in the cost of replacing every inverter at the end of the warranty period as a placeholder for worst case. Every day that they function past their warranty date just improves the ROI.
Good luck on the replacement.

It might change the payback time by a few weeks (mine repaced in 3 weeks), but it doesn't appreciably affect the basic economies of solar.
My replacement SE 10000 just went (and by just I mean 3 weeks ago but I just checked the app today). Man I wish we would be notified when they blow. Lost the first last May and now this was mid June, last time took 3 months to replace. I'm really sick of losing peak production 2 years in a row!!!
If it is another 90 days, what do you think your total losses will have been? ( kWh/$?)
It must really add salt to the wounds not to get notified.
My Solar installer guaranteed production. So if it went off line they paid me lost production and SRECs.
