I have 3 of these units operational 

All at the same site, in parallel or 3-phase? If so, I would not use wildly different firmware version numbers. All the 8 kW Axpert MAX firmwares I have here use the same paralleling constant (118), but I would not trust them to not change the CAN message structures slightly between different versions, causing subtle problems.

The FW 46.05 seems to be stable in the same type of scenario.

Unfortunately I don't have that one to study.

90.06 will do the trick?

Because of the above, I really don't know, sorry.

Hi Coulomb 

They are all standalone, one at my place, one at my Parents and one at my brothers.

It's only the one that uses FW 46.04 that seems buggy.

Thanks

Ok. If you're brave, you could also try version 91.04, from about August 2022, which is supposed to fix some long standing problems with solar charging.

Edit: July 2022 → August 2022.

Hi

Will give it go and let you know

 

Thanks a mill

Hello,

Can any one assist with a F13 error

It's when you exceed the maximum battery discharge current.

The setting for maximum discharge current is disabled by default; my guess is that the battery BMS has set it.

What battery modules do you have, and how many?

Would you have been using a lot of power at the time?

My guess is that you have only a few battery modules, and with an 8 kW inverter, you can draw more power than the battery is comfortable with. So the BMS sends a command to the inverter to limit the battery current, and you exceeded that limit for more than a few minutes, so this fault code comes up.

I assume that you can just restart the inverter and all will be well. Just avoid using too much power at once, unless or until you get more battery modules.
