SMA Solar Technology Reviews 

Similar to previous reviews. My installer warned me but I read good reviews and thought that replacing my 11 year old SMA 3000HF with the SMA 3.0 would be easy. The new one has an APP (why does an inverter need an APP? Mine sat in the loft doing it's thing for 11 years). My installer spent over 6 hours trying to get the damned thing working, Technical support is obstructive to say the least. He went through 3 levels of technical support. They finally agreed to replace it. I decided to cut my losses and just walk away, because I didn't want to go through the whole mess again. I've been asked if the installer is just incompetent. I say no, because they've done a lot of work for me in the past and they get great reviews around Lincoln. SMA are now in the dark ages where solar is concerned. GivEnergy had good reviews but they've gone bust. Growatt and Solis get good reviews, but I'm seriously considering a Fronius. My installer has heard good things already has someone asking for one. He's going on a manufacturers course to get the low down on it.

As SMA users we contacted SMA by creating a service ticket via our profile because we had problems with our inverter. Waiting for an answer for a week now, just to receive a mail, that our service ticket will be closed because information was missing. No mail or question about what is missing, just conveniently closing our service request, so they dont have to do anything about it. Its a scam, when planning a solar installtion, stay a way for SMA, especially if you ever need service from them after spending thousands in installing SMA!

Do not ever buy from SMA. They are a scam. They will do everything in there ability to dodge legal requirements including for warranty replacements, and should not be allowed to trade with an Australia's borders. Their customer support is an absolute joke, beyond unhelpful, and their website is deliberately confusing and misleading. They are a joke of a company and a borderline scam. 0/10 do not buy from this company!! Buyer beware!!

If there was an option to not put a star, I would put 0 stars. I am a technician and have been trying to get ahold of this company for warranty work that has dating back to 2024 and they have still not shipped out. They tell me they are going to every time but nothing is ever done. Absolutely, a disgrace.

As of April 20, 2026, SMA Solar Technology implemented a change to their North American support process, now requiring a support ticket to be opened prior to receiving assistance.

Following this update, I promptly opened three tickets—one of which is time-sensitive, as we require inverter settings in order for the utility to proceed with activating the client’s bi-directional meter.

To date, I have not received any communication from SMA regarding these cases. When contacting their support line and entering the case numbers, I am advised that a written response will be provided; however, no follow-up has been received.

Given this experience, I can no longer, in good faith, recommend this product to clients. While the inverters themselves perform well, the current level of support does not meet the standard required to properly service and stand behind the product.

I have never in my 62 years of life encountered such terrible after-sales customer service. Apparently, if you are not a SMA C&I customer, you DO NOT MATTER.

I am the designer and installer with a degree in electronics, specialising in fault tolerate systems design. If the manufacturer does not support the product, anyone is at risk of long term plant capacity reduction or failure. Beware... "the emperor has no clothes." SMA is not the company it once was.

SMA has gotten so bad with their tech support, it feels like they are trying to race to the bottom. Just tried calling for support and apparently they don't offer tech support for these older inverters anymore although they are still within their warranty date. Also they want a case created online and recieve a case number before they will help you over the phone making onsite tech support almost impossible. Their equipment can be great but without support for problems onsite it really doesn't matter to us and will no longer use or recommend their equipment. Have several commercial sites now that we will be quoting for a different product now.

Reliable real time Information over Long distances.

We have sent a registered letter with acknowledgment of receipt to the management of SMA Solar Technology AG in Germany regarding the installation of a three-phase SMA inverter.

To date, the issues affecting the installation continue to occur regularly, without any lasting solution being provided.

We also regret the lack of follow-up from SMA Ibérica Tecnología Solar in Barcelona, whose support has proven insufficient in addressing the problems encountered.

Under these circumstances, it is difficult to recommend this company, both in terms of customer support and the handling of technical issues.

We nevertheless hope that appropriate action will be taken to resolve this situation definitively.

Two months to get the 5 + 5 years guarantee for the inverter because the commissioning date they had did not correspond to mine (inversion of month and day in Europe). You have to send a case. You have to be an IT to find and understand the answer of the case. I had to phone to ask where I could find the guarantee date. Absolutely not user friendly. Even on the phone they are very difficult to understand because they speak SMA language! I recommend FRONIUS instead.

My fourth inverter malfunctioned. My solar system was installed 12 years ago. Inverter number four, installed under warranty was replaced in 2022 and lasted only until September 2025. Apparently, SMA has a warranty policy which gives you 10 years only from the first inverter was installed. It is difficult to understand that SMA can get around their warranty this way. I will never again purchase any products related to SMA nor will I recommend anybody to purchase SMA products. SMA, if you stand by your product then you should offer a new warranty on each replacement.

Our installation team has been waiting for two weeks to have any assistance with a ticket logged with SMA to assist in removing a device from a plant.
I will be willing to update this review should the issue be resolved, but right now, we have been left with no service and locked out of our own equipment's functionality. The case number is 407488862

Very great technical support with quick follow ups and responsive communication. Highly appreciated!!!

I have a SMA PV system since the year 2020. First, I've installed one single inverter (Tripower 8.0). One year later, I've installed a second battery inverter (Sunny Island), a battery, the SMA's home manager control unit. After this, I've installed two EV Chargers which are controlled by the home manager device. I can charge the surplus of the PV power into my cars. This year, I've installed more panels with a Tripower X 12.
The whole systems works perfectly and had never an issue. I'm just happy and plan my next steps to build more PV panels :)

I have had the opportunity to work with the SMA south african team for 6 years. We have extended warranty on our inverters. The technicians are great and always gets the job done.

The managing director however is the rudest person to get in contact with. His emails is always condescending talking with clients like they are children. Not very helpful and not very friendly especially since you are supposed to always treat your customer with respect. The guy can never give straight answers. Not very helpful service from them at all. Not likely to recommend SMA to any person since you get treated badly by the SMA team

I would like to take a moment to express my sincere appreciation for the outstanding support we received from SMA and, in particular, from IRIS.

Based in Egypt, we were recently approached by one of our valued clients who was facing a critical and urgent technical issue. The situation had become quite frustrating for him, especially after multiple unsuccessful attempts to resolve the problem through various channels.

Upon receiving the client's request, we immediately reached out to SMA for assistance. To our great satisfaction, our query was promptly forwarded to IRIS, who demonstrated exceptional dedication and professionalism from the very beginning.

IRIS was not only quick to understand the severity of the issue, but he also took proactive steps to ensure it was addressed without delay. He personally called me to discuss the matter in detail and, as per our request, made himself available early the very next day to provide the required support.

Thanks to IRIS’s prompt action and continued commitment, the issue was successfully resolved, restoring our client's trust and satisfaction.

We are truly grateful for the support provided by SMA and extend our heartfelt thanks to IRIS for his unwavering dedication and outstanding service. It has been a pleasure working with such a responsive and professional team.

Ash Best regards
I would like to thank Engineer Mohamed Youssef for his continuous and constant technical support in handling matters.
I also thank this team for the technical support of SMA Company.

SMA, has one of the worst customer support.
I have a10kW Sunny Tripower Smart Energy Hybrid inverter. It has chaotic behavior, on PV generation. In sunny day, without clouds, it changes the pv generation between 0kW to 10kW, from second to second, with nothing to obstruct the PV panels.
It measures with approximately 3V more on the AC input, than any other multimeter( I have made AC measurement with 3 different multimeters, all have same readings) or even than the SMA Energy Meter. From this reason it enters verry often in Standby mode from over overvoltage event.
Every 2-4 weeks it changes by its own, the data logging from "on" to "off", without human intervention.
If there is an AC grid failure, sometimes the backup output is also shutoff - the main purpose of an hybrid inverter is to have power on the backup output in case of grid failure.
It changes the value measured for consumption from 0w to 5-6kW on the house from second to second, even if the load is constant of 500W. Should this be normal behavior?
The SMA Energy Meter... from time to time, you need to disconnect it from the grid, to reset it, because it measures the power consumption way off.

The site for technical support, does not work properly, it allows you to make tickets for support, but then you can not access the content or read the replays from SMA. Some times you get an email with the response, and so you can see the answer, but most of the time the answer is not accurate or not for the current topic, or they give you link to the manual.
Not professional at all in my opinion.

Not to mention that this invertor is 100% Chinese design from Sungrow, sold as German design and technology. I fill that I am being lied and taken as a fool by them.

SMA Home Manager 2.0 is not working properly with their new portal. In the old portal you can access more configurations like "Time window control for charging the battery-storage system", unfortunately this is also not working. I set the charge to be done between 12-13, and at 10AM the battery was already 100% charged...
To summarize, the system is not working properly and I have no solution from SMA.
I will never buy SMA again until they improve the customer support, and applications.
It is better not to have than to have something that is not working properly.

I've had my solar array for less than 10 years. The SMA Sunny Boy Inverters have a 10 year warranty. As I said, it's less than 10 years old and I'm in the process of getting a 2nd inverter replaced in that amount of time. It's not much of a warranty if they don't actually replace the faulty parts. I've now been waiting a month for delivery of the new inverter. So for a month I've been only utilizing 1 of my 2 Inverters. So in the time of year where I should be making / storing power, I'm making half the power I should be because of these Inverters and a company that is dragging their feet getting a replacement sent out.
