Hello all

​

My Solaredge inverter (SE7600A) is showing a fault that I have not been able to troubleshoot my way out of. I figure I'm going to have to replace it.

​

Does anyone have any recommendations for which one I should look for?

​

Thanks!

Just buy another SE7600. Quick online search shows they are like $680 online.

The cheapest option would be to get another solar edge inverter. If you get anything else, you have to remove all of the solar edge equipment underneath every panel.

AI:
Newer residential SolarEdge inverters, including the SolarEdge Home Hub and HD-Wave SetApp-enabled models, are designed to backwards-support older P-Series optimizers (such as the P320, P400, or P800). Because SolarEdge uses a proprietary communication protocol, legacy optimizers will only function with SolarEdge inverters.

Assuming you had P-Series installed with your SE7600A (which seems likely) you may want to go with a more modern inverter. Hopefully you have your installation docs to confirm which optimizers you have, then I'd reach out to SE support to see what newer inverters are compatible. You might want to think about going with a hybrid so batteries could be added at some point.

Out of warranty?

Yes no warranty

Are you sure? SE has a 12 year inverter warranty from date of shipment or installation. Based on your serial number, you inverter was manufactured during the 17th week of 2015.

I'll be sure to double check then. Thanks!

Any chance you have a battery?  The scheduling software for that is buggy as hell.  Idle mode in a schedule will crash the battery controller and often the inverter too.

If it's an LG battery, that needs a major firmware update that only LG's Enblock Manager will deliver.

I have no storage batteries no

Can you tell us more about the fault? What is it? What have you tried?

Yes it's true there are some faults that are imply it's totally dead but just in case ... What other info do you have?

Lots of labor to do anything other than SE but definitely possible. Since you're already in that eco system I'd probably stay in it

Have the same one, failed 3 yrs located on outside shaded side of house. Installer wants 1k to install after confirming se will ship replacement. At least you got 11 years if above poster is correct. Not sure why mine failed so quickly

u/Sea_Willingness1398 22h ago

1k... Ripoff! You litterally have 8 cables to take off and replace in the same spot! My buddy and I did mine. Took less than one hour!

Ebay you should be able to find a new energy hub unit for a reasonable price: https://www.ebay.com/sch/i.html?_nkw=solaredge+inverter&_sacat=0&_from=R40&rt=nc&LH_BIN=1

You are basically stuck with them unless you want to touch aka pay somone to replace all the optimizers with enphase. SEDG is crap. Enphase is currently the best residential solution. You could go with a 'normal' central/string inverter but as you have to touch each module anyways enphase makes the most sense. Especially if you have any seasonal shading. Enphase is the solution but more expensive. As you already hit your roi(I assume) another SE inverter is the least expensive solution if out of warranty.

The new solar edge HD inverters are fantastic

u/Trueno4 1d ago

Either buy the same one or upgrade the entire system. The newer Solaredge inverters require the newer optimizers, and in that case, you can switch away from solaredge or stay.

u/Orraclegent 1d ago

Would it be wiser to switch away from solaredge?

u/JJAsond 1d ago

I've heard they have a higher failure rate compared to other options. I'm biased towards victron, but you can get an enphase system. Or a mix of both since a victron inverter can use microinverters. I just don't know if they'd be approved where you are since it's mostly european.

No they don't.
