I have a Mulitplus 24/1600/40-16.
I want to load the battery + use the rest active for loads.
If I had no battery + rest from the solar panels (20 % Reserve), I want to change to the normal grid.
I can't find infos to make it with die Virtual switch.
I thought to update to ESS, but is not possible I have an old Firmware 2616413.
If I Register to the homepage (Professional Site) is it possible to update to the latest Firmware.
Software says 2616415 ??
Thanks for your help.
