USE WITH SOLAR CONTROLLERS OF THE MPPT
plus
+
SERIES
When using the remote control with solar controllers of the MPPT
plus
+
series, the following option for operation and
adjustment are available:
Figure 3: Basic menu MPPTplus
+
Figure 4: Parameters of the MPPTplus
+
Figure 5: System parameters
In the basic menu the display shows a
moon/sun symbol
, a
solar controller symbol, a battery symbol
and a
bulb symbol
.
The respective energy flow of the solar system will be indicated by arrows situated between the system components.
Underneath a diagram displays the real time charging capacity of the solar controller related to the time factor.
Based on the
moon/sun symbol
it becomes apparent if there is sufficient solar power.
If the
moon symbol
is being displayed the voltage supplied by the solar panel is lower than the current battery
voltage. If the solar voltage is higher than the battery voltage, the display will show a
sun symbol
.
Activating one of these symbols, leads to the display of the current solar input parameters.
(SOLAR PANELS).
This view shows the solar voltage, solar current and the solar power.
By activating the
check symbol
you may return to the basic menu.
The
battery symbol
informs you of the current battery status by displaying a full or an empty battery.
When this symbol is being touched, the current battery voltage will be shown.
By activating the
hash symbol
may return to the basic menu.
By activating the
solar controller symbols
you may influence the charging behavior of the MPPT
plus
+
solar
controller. In this case a view will be opened in which the cut off voltage
(CHARGE)
, the deep discharge
threshold
(DISCHARGE),
temperature compensated charging
(TEMP COMP.)
and maximum charging current
(MAX CURRENT)
may be adjusted
individually.
The adjustment will be done after choosing the respective parameter by using the „+“und „-“ buttons.
By activating the
return arrow symbol
you may return to the basic menu.
CHARGE -
cut off voltage
The information regarding the cut off voltage refers to the charging step 1 of the MPPT
plus
+
and can only be
modified when using lead (
open, GEL, AGM)
batteries.
DISCHARGE - deep discharge threshold
The value of the deep discharge protection indicates at which battery voltage the load output of the
MPPT
plus
+
will be deactivated in order to protect the battery against harmful deep discharge.
TEMP COMP. - temperature compensated charging
If temperature compensated charging is activated, the values low
(LOW, 25 mV/°C),
medium
(MID, 30 mV/°C),
high
(MAX, 35 mV/°C)
may be chosen. The cut off voltage will then be adjusted
according to the temperature. The maximum value of the cut off voltage is 14.7 V.
The use this function the connection of the external temperature sensor is mandatory.
MAX CURRENT
This parameter allows the limitation of the maximum charging current fort he battery.
Attention! An inappropriate adjustment of the charging parameters may cause fatal damage to the
battery. Always note the information provided by the battery manufacturer.
