Sunny Boy Inverter Repair
We diagnose and repair SMA Sunny Boy string inverters across Fresno, Clovis, and Madera. SMA inverters are among the most reliable in the industry — but when they do fail, we identify the fault and restore production. We service current Sunny Boy models and legacy units going back to early Sunny Boy 3000/4000/5000 series.
We service SMA systems from any installer, including companies that are no longer in business. Licensed contractor #1063682. Serving Fresno County and Madera County.

SMA — Common Questions
What is the SMA Sunny Boy warranty?
SMA Sunny Boy inverters carry a standard 5-year warranty, extendable to 10 or 20 years with a warranty extension. If your inverter fails within the warranty period, SMA will provide a replacement — we handle the installation and documentation.
Why is my SMA Sunny Boy showing a red light or error code?
SMA inverters display error codes for grid faults, isolation faults, overtemperature, communication errors, and hardware failures. Common codes include Insulation Fault, Grid Fault, and Overtemperature. We diagnose the specific code and determine the repair path.
Can you repair an older SMA Sunny Boy inverter?
Yes. Many older SMA Sunny Boy inverters (3000–8000 series) are repairable. Common failure points include capacitors, fans, and communication boards. We assess the repair cost vs. replacement cost and give you an honest recommendation.
How do I reconnect my SMA Sunny Portal monitoring?
SMA Sunny Portal reconnection usually involves resetting the SMA Data Manager or Webconnect module, verifying the home network connection, and re-registering the device. We handle this on-site for all SMA communication hardware.
My SMA inverter is producing less than expected — what should I check?
Check the Sunny Portal for any error codes or production gaps. If the inverter appears normal but production is low, the issue may be shading, dirty panels, or a DC wiring fault. We perform a full production audit to identify the cause.
