Hello.
I have a problem with the new 3.50 update of Venus OS, I can control the inverter mode only trough VRM.
When i try to toggle the mode on the display “touch 50” or remote console, i get the message “The mode is fixed in the system configuration. it cannot be adjusted”.
The inverter is 12/1200 model.
Relatively new to the GX, but feel i have got to grips with it for the most part.
Looked trough the settings, but there seems no obvious way to enable control from the display.
the physical switch works, switching from VRM works.
I can operate the relays with the display just fine, so there’s a possible workaround to switch it with one of the relays.
Inverter/Charger Control is on if it is off turn it to on
Toggle Inverter/Charger control for this installation. By turning this on, you will be able to remotely control your inverter’s current limit as well as switch it on, off and to charger-only from the Control Panel on the VRM Dashboard.
Enabling this option is not recommended for mission critical applications. This option will allow a VRM user to shut the system down and change current limits which could affect system stability.
I check my system Phoenix 24/5000 on old UI there are options to toggle the mode in the new firmware there are no options so you are right my mistake I have the same problem as you and the same message.
It is something that Victron miss and only Victron can fix in the new firmware in my opinion.
