Do SolarEdge Inverters suffer from wear issues on the flash memory?

[cyberkryten]

Describe the bug

There have been changes made to Predbat for GivEnergy inverters because register writes are causing premature wear of the on-board flash memory.

There are many parameters being changed when using this integration to control the inverter, so an understanding of whether this is something we need to be concerned about would be good.

Has anyone got an answer or asked SE about this?

I note that there is a warning about this in one of the more recent SolarEdge TerraMax Inverter technical notes, though I can't find any reference in others :

https://knowledge-center.solaredge.com/sites/kc/files/se-modbus-interface-for-solaredge-terramax-inverter-technical-note.pdf

At the bottom of Page 19:

The adjustable parameters in Modbus registers are intended for long-term storage.
Periodic changes in this parameter may damage the flash memory.

Due to the way the SE inverters reset daily and also have a default command timeout of 1 hour, it is necessary to write the status to the inverter regularly, so this is a concern if it does affect SE Inverters - without knowing the MTBF and wear details, it is hard to know if current writes are within limits or likely to cause major problems.

Expected behavior

Change settings without causing premature failure.
