NOTICE!
Transfer of grid operator setpoints via RS485 not possible during firmware
update
During the firmware update, the Sunny WebBox does not send grid operator setpoints via
RS485 to inverters in the system. Thus, the grid operator cannot control the system.
• If you want to perform the firmware update during feed-in operation during the day,
contact your grid operator in advance, if necessary.
