Multiplus reboots after remote VE config

Good day,


I have a Multiplus ii 48/5000 230V, with a Cerbo GX and a 5Kw LFP battery running ESS.

I have recently upgraded the Multiplus firmware from V497 to V502 in an attempt to hope this will fix Eskom brown out issues when the grid is failiing.

After the update I've reconfigured the Multiplus using remote VEConfigure, and noted the multiplus reboots itself when the config file is uploaded, dropping everything on AC1.


This did not happen on the previous firmware version V497 and would update without any reboots.


Any advice on why this would happen?

Remote veconfigure will restart the inverter. Pretty much always has because it reloads the full config.

There is nothing in recent inverter firmware that will improve eskom’s grid issues.

this is interesting, as this never happened on V497. only after the recent upgrade.


While on the topic of Eskom as well, Do you perhaps have anything to try, when switching over from grid to battery my output voltage sometimes dips as low as 80V, sometimes its instant. When i try and simulate this by turning a breaker on and of this is perfect every single time with no dip what so ever. I think Eskom grid might be causing this.
