If your SMA or Sunny Boy inverter is showing a fault light, an error code, or no data, we diagnose and repair it, whoever installed your system.
We identify what is triggering the fault before recommending that any part be replaced.
SMA inverters, including the widely installed Sunny Boy line, report problems through specific codes and status lights. Some of those faults point to a real component failure. Others, like a grid-related or communication-only fault, often clear without any part being replaced.
We identify exactly what is triggering the fault and confirm whether it is a wiring issue, a settings issue, or an actual component failure before recommending anything, so you are not paying to replace equipment that is working fine.
SMA has supplied residential inverters for many years, so many SMA and Sunny Boy systems still running today are older installs, sometimes with an original installer who is no longer around. We evaluate your system as it exists today, and you do not need your original installer involved for us to diagnose and service it. If the inverter is beyond repair, we also handle inverter replacement, and for problems that may not be the inverter at all, see our solar troubleshooting and repair service.
Renew Solar Services diagnoses and repairs SMA inverter systems throughout Nassau and Suffolk County, including Hempstead, Mineola, and Farmingdale in Nassau County, and Holbrook, Huntington, Commack, Riverhead, Hauppauge, Brookhaven, and Southampton in Suffolk County.
Tell us what code or status light your SMA inverter is showing and we will help you figure out what it means.
Yes. We diagnose and repair SMA inverters, including the Sunny Boy line, regardless of who originally installed your system.
It can be. Some SMA faults, like a communication fault, mean the inverter has stopped reporting to its monitoring platform without necessarily affecting production. Others point to a real issue that needs attention. A proper diagnostic check is the only way to know which one you are dealing with.
Not necessarily. Many SMA faults trace back to a specific, addressable cause rather than the entire inverter failing. We diagnose first to confirm what is going on before recommending a repair or a replacement.
