I am considering updating the firmware in my Quattro using VRM. The cautionary message explains how how, after updating, the Quattro is reset to the default configuration except the charge current is set to zero. This configuration is then saved to my PC where I am to open it with V.E. Configurator by double clicking. I am to save the configuration file by closing the configurator and then upload the configuration file to the Quattro. The cautionary message closes with this: “Last stage: on VRM, go to Device List → Remote VEConfigure and there use the Upload feature to upload the settings. This will restore the charge current.”
My question is: to what amperage is the charge current restored? The factory default? The non-default amperage setting I was using before the firmware update? Something else?
It is supposed to not charge when you have uodated it over the vrm. But it depends on what version you are moving from. The older ones didn’t always not start charging before reconfiguration.
ts always safer to disconnect ac in and out/load when updating. Ir at least that has been kept in out SOP for updates.
Save this first. Then do the update when working iver the vrm.
I must not be communicating clearly. If the charge current was set at 112A before the update, will the described update procedures keep 112A or will they revert the Quattro to 165A, the factory default?
During the update process, the VRM website will download the config file to your PC. This config is from the old firmware version. You then open that file with VE.Config and confirm that all values are correct, including the charge current at your custom 112A. Then you upload that config to the newly updated device through VRM.
If you dont check the config or if you dont upload the updated config, then the charge current might not be correct after the update
