Does anyone know how to change setting 04 from default 43.6 volts to 50 volts? I want my batteries to start charging from the grid if it goes below 50 volts I'm in SBU mode it let's me change it but it doesn't stay goes right back to default. I can change any other setting except setting 04.

It doesn't say it in the manual but you have to change the setting in 15 and 12 to be able to change the settings in 04
