Before this menu function is activated, it is necessary to disconnect the solar PV modules and all
loads. Before Uninstalling (chapter 6.5, page 13) please refer to the related information. After having scrolled to this
window, a self test can be started by pressing OK. The System-Manager examines its performance components:
software and parts of the hardware. When the window appears ”TEST: SUN+ LOAD+”, the operation and hardware
have been verified to be in good condition. If ”TEST: SUN
−
LOAD+” or TEST: SUN+ LOAD
−
” appears, re-start the Test
again after you have verified that the modules and loads were properly disconnected. If the failure message appears
again, disconnect all connections and please return the System-Manager to your authorised dealer.
Within this menu, the battery electrolyte type can be set. After having entered this menu, by pressing
OK you may toggle between

fixed to liquid electrolyte. Setting this to fixed deactivates the window for
programming the acid density as well as disabling the equal charging mode since gassing must be prevented where
sealed batteries are used.
possibilities for programming:
liquid, fixed
The end of charge “float” voltage serves for maintaining the charge in the battery for long periods
and preventing self-discharge. This voltage should not be too high, since this may lead to permanent gassing, which
damages the battery. Maximum values are stated on the battery data sheet of your battery
possibilities for programming:
13,0V...14,5V
26,0V...29,0V
52,0V...58,0V
Increasing the charge voltage over a limited period of time (boost or “bulk” charging) is not harmful
for lead battery types, if within certain parameters. Maximum values are stated on the battery data sheet. After having
entered the window by pressing OK, you can change the voltage values by pressing the arrow keys
▲▼
. This setting
can be confirmed and stored by OK.
Possibilities for programming: 13,5V...15,0V
27,0V...30,0V
54,0V...60,0V
The equalisation charging can be programmed similar to adjusting the boost charging. Press OK to
enter, edit the equalisation charge voltage by pressing the arrow keys
▲▼
and confirm setting by pressing OK. The
equalisation charging can only be adjusted for batteries with liquid electrolyte, since high equalising voltages are harmful
for sealed batteries. The maximum equalising voltage value should be stated on the battery manufacturers’ data sheet.
This window is deactivated if you have selected “electrolyte fixed“Fehler! Verweisquelle konnte nicht gefunden werden.
presumes liquid electrolyte batteries.
Possibilities for programming: in the period from
14,0V...15,5V
28,0V...31,0V 56,0V...62,0V
Battery charging voltage is passed on directly to the loads by the System-Manager! Therefore,
during equalise charging, high charging voltages can be programmed that may damage some
loads. Please select this equalise charge voltage very carefully and compare the desired value to the
battery and load (appliance) manufacturers' data sheets.
The discharge threshold at which the loads are automatically disconnected can be programmed by
the user. When you have reached this window by pressing the arrow keys
▲▼
, you may open it for editing by pressing
OK. Afterwards you may alter the disconnect threshold by pressing the arrow keys
▲▼
within given values. Press OK to
store the setting. NOTE: the difference between disconnect and reconnect threshold must be at least 0,13V/cell. If you
wish disconnect at higher state of charge you have to first adjust the reconnect threshold (as per below) to 0,13V/cell
above the desired disconnect threshold.
Possibilities for programming by voltage regulation: 11,0V...12,5V
22,0V...25,0V
44,0V...50,0V
The charge threshold at which the loads are automatically reconnected, can also be programmed by
the user. The reconnect setting window is reached by pressing the arrow keys
▲▼
. Enter the window by pressing OK,
and alter the values within the window. Press OK to store the setting. The reconnect level can only be reduced to
0,13V/cell above disconnect threshold (see above).
Possibilities for programming: by voltage regulation: 11,8V...13,3V
23,6V...26,6V
47,2V...53,2V
