Don't trust anyone who claims that this is a good product

While buying a house with a 12kw SMA installed, it was observed that the inverter wasn't working. I got the original installer to assess. The unit was 6 years old. The unit was fried and based on the assurance that SMA was a top brand and nothing like this had ever happened before, I was talked in to replacing the unit with a second hand one. Fast forward two weeks and I now own the house, and the second inverter is fried. Now I have to find over $5000 for a replacement.
Based on my limited experience, SMA is no better than Chinese units at half the price. If the cheap ones only last the life of the warranty, you will be ahead.

Faulty and terrible support

Our SMA Sunny boy inverter has a fault after 4 years. Installer was unable to diagnose as there was no to access without password which we had lost during a renovation. Very unclear technical customer support. requests in end via facebook messenger for support. Then set up a case number in SMA online help which had no response and then was then wiped by SMA (without even being made a closed case). Installer managed to finally diagnose the inverter fault and 10 days since there is no ETA at all around when will be sent out. Over a month now without solar. Would not recommend this company at all.

Unreliable Wifi

Had the SMA inverter installed 11 months ago. After 8 or so months no wifi from inverter to my mobile phone app as also experienced by some other customers here.
It is complex and difficult working through trying to get this rectified. Installer does not want yo know about it, because Ozzy Solar in Adelaide do not honour their obligations on after installation customer warranty service.
The Inverter works ok. I just hope long enough. I would not go for another SMA inverter, should this one stuff up sooner.

Over rated for over priced inverter

Not recommended. It's now been more than 4 weeks since my Sunny boy 6.0 failed after only 3 years. No support in sight.

"Regarding your case #xxxx unfortunately we have been experiencing supply chain delays as we transition to a new Service Partner in Mexico.

I can assure you we are actively working to resolve these delays. Unfortunately, I don’t have a set date of material availability at the moment, but will reach out to you as soon as I have more information from our various teams working on this.

I do appreciate your patience and business with SMA."


I cannot believe how bad it can be for the amount of money you spend on a product

I cannot give you the whole story because it's to long and depressing. In short buy victron or anything else. If a system is off grid and the support system is on a internet connection and you don't have that well, don't buy sma.

Terrible after sales service

I am unable to link my new SMA inverter to the app on my iphone.
No useful help forthcoming from SMA at all.
Just long complex unhelpful technical instructions.
No response to my request for a telephone call to explain the procedure.
Two capable technically aware people, one a computer engineer have also failed to make the apps work.

SMA Sunny Tri Power 10kW

I got mine installed in last week of Feb-21 and it failed on 31 Dec 2021. Now waiting for the warranty replacement. I am now told that I should expect a replacement inverter in February. I was told this is the best so paid more for it.

Sma owns majority of zeversolar

My extended warranty I purchased and sent in 3 yrs ago and sales staff tried as well to send through to the warranty department. Just found out I paid extra for warranty and no extra warranty even though I sent registration in many times with no reply only from sales staff who sent it in as well on my behalf and sent me email showing they did (my proof). 3 yrs in and inververter died. So SMA you own them now and you are responsible. The warranty department not once have replied to my dozen emails, 3 yrs ago and now. Extended warranty I was scammed.

1/11/20 Update, received email today from zeversolar confirming my extended warranty, apologise for the late reply, 3 yrs late mind you. So have given an extra star for that.

Poor Quality

We had a SMA Sunny Boy 2.0 Kilowatt Inverter installed with a solar panel installation the warranty period was 5 years , it died after 5 years and 8 months , error code pertaining to internal fault , you would think that with such a short period out of warranty that SMA Australia would offer a discounted replacement or low priced repair , and I quote " No it is out of warranty " . With such an expensive brand that is " Made in Germany " one would expect more then 5 1/2 years out of an inverter , to add insult to injury I was informed that there was an optional 10 year warranty that I was not told about at the time of purchase !

Warranty not worth the paper its written on

I have a Sunny Boy SB 5000 TL installed 9/14, An error fault varistor defect, rang the installer said the varistor not covered on warranty $214 to do the job, rang sma they don't cover the varistor, I thought the varistor was part of the inverter, I'll be bagging sma from now on, here I was saying sma sunny boy are good inverters but the company wipe there hands with this part. Not happy.

No service

Had 2 sma inverters installed a year ago. One died 2 months ago. Still unable to get the replacement. Can't get through when calling them. Extremely disappointed as I have been promoting them in our area and to friends.

Can confirm... IT IS IMPOSSIBLE TO GET HELP. Got through after holding for 11mins today and was asked for a reference number. Called back 4 times and, THANKS TO PHONE NUMBER RECOGNITION, I held for an average of 14min before call ended automatically.


Impossible to get help

I had a Sunny Boy SB 5000 TL installed 6/14. An error fault displayed last week 'varistor defect'. Spoke to the installer who asked me to contact SMA, but it's impossible. The phone extensions go dead and despite 2 emails to the service department I've had no replies. This is supposedly a premium inverter but with sub prime back up. They really need to get their service house in order. I will keep trying.

I got a jinko solar panels with a sunnyboy 5.5 inverter installed. The inverter is new design with no lcd screen. It does have a wi fi system so that you can used it on your computer or mobile phone. Sometimes the next morning you cant get it to connect to your phone. Then you have to go to your meter box outside turn every thing off for 1/2 min and back on to reset. Once on the net and see how it works i got a date of august 2015 now December. IT is not adjustable. I sent a email to head office in Germany who gave me details of SMA Australia. Try and get hold of them for 2 days. I spoke to some lady who tell me their technicians are busy. Their after market service does not exist. The system with the jinko panels work great. Their computer program? i don't know. Their after market service?


Has anyone had failure with victron Quattro ,mine's a heap of you know what? wally
