SMA · SUNNY BOY SMART ENERGY Inverters
All three LEDs (Green, Red, Blue) glowing solidly at the same time indicates that the inverter is either performing a software update or is going through its initial booting sequence.
Click steps to track your progress.
Wait for the booting or update process to finish; do not interrupt the power supply during this time.
Ensure a stable power supply to prevent any interruptions or data corruption during updates.
If this state lasts for an unusually long period (e.g., more than 10 minutes), try cycling the power by turning off and on the DC and AC breakers.
