Check this https://github.com/manio/skymax-demo/ https://github.com/manio/skymax-demo/issues/23 or check ned-kellys forks. Maybe someone add a little code to go with it.

There is also on this forum 60.06 firmware patched by Coulomb. or in topic firmware 60.66 that fixes charging from the grid . But I do not know if it is better than yours.

And what was your previous firmware number? A couple posts before Tarek no complains about 60.05 firmware. Maybe worth to try.

Yes Axpert VM III is on the list supported but they do not mention about newer TWIN model. Changelog doesn't mention about that too. So I'm not 100% sure.

Hi Is Axpert VM III Twin is supported from SA??

Oh I know. I mean that You got 123V in panels but Coulomb up starting MPPT voltage to 150-200V. So I think start MPPT will never happen in this situation. Am I wrong?

PreviouslyTarek said: So I do not know if mppt start at 150V ??? Thanks Coulomb for the firmware. Now I can buy this inverter.

HI Is there any disadventages in 60.05 firmware?

This is statment from Noctua site: so I think 3 pin fans without PWM and VMIII board without PWM fan controller should not set fan to 0% PWM .

Hi I think First of all You should go with more panels to shorten both ends of the PV graph with 60V stuck. 123V is far from inverters nominal voltage. Best
