Voltronic Axpert VM IV - Power saving mode/Turn off inverter in bypass mode

[john1819]

Hi,

I got Voltronic Axpert VM IV, but idle power consumption is high 80W in passthrought/bypass mode, its there is a option to turn inverter off when battery its low 30% and turn it on when above 80%? Different firmware?

Is there a program to edit firmware and make own?
