Neovolta NV7600 inverter

I was given the Solarman app installer permission so I could change the time of use hours and battery %’s. This is the guidance my installer got from Neovolta themselves.

I still can’t change the hours on the inverter itself. I think he only gave me upper access to the app.

Anyone able to make time of use, battery % changes and watt discharge amounts? What did you have to do? Thanks.
