6 CONFIGURATION
6.1
Programming your Solar ChargeMaster
With a long push (2s-8s) on the button the
programming mode is opened. The programming
menu structure is described in the table below. A
black wide arrow means a long push (2s-8s), a grey
arrow means a short push (<1 sec). The dotted lines
under “Setting” mean you see the actual selection
there. During selection the symbols under “Settings
menu” are flashing.
When you exit the configuration menu, the
controller displays the state of charge (available
energy) of the battery and the status of the load.
Mind that once you have entered the
configuration menu you can exit it at the
last item only.
We therefore recommend that you first note
down your required settings and then do the
configuration in one go.
All configuration settings are stored in a non-
volatile memory and remain stored even if the
controller was disconnected from the battery.
