SMA Certified repair company

  Is your SMA inverter blinking red, showing a yellow disturbance light, or displaying an error code like 3501, 4301, or 102? We test DC string voltages, isolation resistance, and AC grid parameters on-site to identify the exact point of failure. 

  If your older SMA unit has reached the end of its operational lifespan or suffered internal power board failure, we provide seamless replacements with current SMA Sunny Boy models, matching your existing array layout and roof wiring.  If your older SMA unit has reached the end of its operational lifespan or suffered internal power board failure, we provide seamless replacements with current SMA Sunny Boy models, matching your existing array layout and roof wiring. 

  Lost your inverter's connection after changing your home Wi-Fi or router? We reconnect your SMA inverter to Speedwire or Webconnect, reconfigure your local network, and restore real-time monitoring on the SMA Energy App. 

  SMA inverters will shut down if they detect a drop in isolation resistance ($R_{iso}$). We perform Megger insulation testing across your rooftop DC strings to locate damaged wires, pinched conductors, or roof leaks.  

 Error Code 3501 / 3502 (Insulation Resistance / R_{iso} Low)  

 Error Code 102 / 103 (Grid Overvoltage / Undervoltage) 

 Error Code 4301 / 4302 (Open Circuit Voltage Too High)
