9 FIRMWARE UPDATE

9.1 General
This chapter describes how you can update one or more inverters if you have an inverter with a more recent firmware.
As already illustrated in the manual par. 4.2, for use in multi-inverter configuration, it is necessary for all the
components that are to be put into communication to have the same firmware versions. If they are different, they must
be updated to align the older versions.
Definitions used below:
Master: device from which a firmware is taken to load it in another inverter.
Slave: inverter in the state of receiving a firmware update.
9.2 Update
When several inverters are connected together, a control procedure is started which compares the firmware versions.
If they are different, the inverters each show a pop-up that communicates the state of non-alignment of the firmware
and the version of their own installed firmware.
The pop-up allows you to proceed with the update by pressing "+" on any one of the inverters. The firmware update is
carried out simultaneously on all the connected inverters that require it.
During the update the Slave inverter shows the message "LV LOADER v1.x" and a bar indicating the progress of the
update.
During the firmware update the Slave and Master inverters involved cannot carry out pumping functions.
The update takes about 1 minute. At the end of this phase, the inverters will restart.
Once they have been restarted, they can be connected and form the multi-inverter group.
If problems have occurred and the firmware has not been correctly installed, the Slave inverter might remain in an
inconsistent status. In this situation the message "CRC Error" appears on this inverter. To correct the error it is
sufficient to disconnect the power supply to the Slave inverter, wait for it to be completely switched off, and then supply
the power again.
Switching on the Slave inverter automatically generates a new update process.
