Miserable tech support system

I am writing to express my extreme dissatisfaction with the technical support provided by SMA Solar Technology America. I am an experienced master electrician with decades of experience in electrical systems, industrial controls, troubleshooting, and equipment installation. I am accustomed to diagnosing complex electrical problems and working with manufacturers to resolve technical issues. Unfortunately, my experience with SMA has been exceptionally frustrating. I am currently troubleshooting an SMA Sunny Boy SB7.7-1SP-US-40 inverter. The original inverter was replaced, and I have successfully commissioned the replacement unit. The DC input voltages appear satisfactory, the AC supply is present, and the inverter reports an acceptable device status. Nevertheless, the inverter produces no output current, and its grid relay remains open. I have reason to suspect that the original rapid-shutdown (RSD) communication board, which was retained when the inverter was replaced, may be incompatible with the replacement unit. I have provided SMA with a photograph of the original board and specifically requested confirmation of its compatibility. I am awaiting a response. My complaint concerns not only this unresolved technical problem but also SMA’s extremely difficult support process. The company’s website is unnecessarily complicated and makes obtaining meaningful technical assistance far more difficult than it should be. Reaching someone capable of addressing a specific technical question has become an exercise in frustration. A manufacturer of sophisticated electrical equipment should provide competent, accessible technical support, particularly when customers are attempting to restore equipment to service. I am not asking SMA to diagnose a problem without adequate information. I am asking for reasonable cooperation, timely communication, and clear technical guidance regarding equipment that SMA itself supplied. I am requesting that SMA management: 1. Confirm whether the existing RSD communication board is compatible with the replacement SB7.7-1SP-US-40 inverter. 2. Provide a qualified technical representative capable of assisting with the unresolved no-output condition. 3. Identify any required configuration changes or replacement components. 4. Improve the accessibility and responsiveness of its technical support system. At present, I have an inverter that has been commissioned but remains nonproductive, despite considerable time and effort spent troubleshooting. I believe SMA’s customers deserve substantially better support than I have experienced. I would appreciate a substantive response from SMA management and a clear path toward resolving this problem.

6406 failure.

This is the second time I’ve had a 6406 failure. The first inverter lasted almost two years. It failed. 2 hours on the phone, they sent me a replacement power unit. Failed again two weeks ago, exact same issue 6406. MPP A is out just like before. They no longer answer the phone. Submitted case online. But they don’t respond or care. Absolutely awful. I wish they would just go bankrupt.

Do Not purchase an inverter from SMA

Purchased Solar system with 4 Sunnyboy inverters. Commissioned 11/03/2022. Two inverters stopped working January 2026, Submitted case to SMA cannot get a response. System has been down for 4 months, This is a large commercial system. Would NEVER do business with them again Too avoid costly headaches, steer clear

Unless you are a grid scale customer, DO NOT PURCHASE SMA PRODUCTS

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

Tech Support

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.

Absolute worst technology on the market

I have been designing and installing RE systems since 1999. I am a licensed C-46 contractor and a certified installer for: Tesla, Enphase, Sol Ark, Simpliphi, Point guard (Sig enrgy), Outback, Fortress Power and more. I have never in my life experienced such a massive waste of time, and money such as the commissioning process of a simple SMA inverter. I have installed only 3 of these residential inverters in the past couple of years because I focus on systems with energy storage. All 3 have failed. The commissioning process makes absolutely no sense and immediately after your create your admin credentials the app as well as the Sunny Portal will forget your credentials and you will no longer have access to the SMA 360 commissioning portal or the monitoring platform. I have had to delete my credential no less than 6 times and re create them only to continue to not be able to commission the systems. I have had new comms boards sent out only to have them not funtion straight out of the box after waiting several weeks for a RMA to be processed. Customer dis service is a nightmare and intolerably inept. Every phoe call is a 45 minute wait for a pick up only to have the disconnect and/or pass on to Tier 2 for another 45 minute wait and no resolution to the manner. I commission hundreds of systems every year with only minor issue. This company is atrocious and no one should ever think about using their tech. There is no recourse for the countless hours wasted on attempting to replace, commission and simply get the inverters to function. ABSOLUTE FAIL!!!!
