Firmware Update in a System with one Sunny Island Inverter
Firmware Update in a System with Several Sunny Island Inverters
In a system with several Sunny Island inverters, the firmware is only updated on the master. If the
master detects that a slave has a different firmware version, it transmits its firmware to the slave and
makes sure that all Sunny Island inverters within a system operate with the identical firmware version.
While the master updates the slaves, the devices display, among others, the following messages.. The
display duration of the display messages listed below may vary. Wait until the master displays the
message ”Update finished. Press Enter” and the slaves display the message ”Ready. Wait for
Master.” Do no enter anything while the update is running.
