For example:
12V battery and mono- or polycristalline panels connected to a 75V controller
● Minimum number of cells in series: 36 (12V panel).
● Recommended number of cells for highest controller efficiency: 72
(2x 12V panel in series or 1x 24V panel).
● Maximum: 108 cells (3x 12V panel in series).
24V battery and mono- or polycristalline panels connected to a 100V controller
● Minimum number of cells in series: 72
(2x 12V panel in series or 1x 24V panel).
● Maximum: 144 cells (4x 12V panel in series).
Remark: at low temperature the open circuit voltage of a 108 cell array may exceed 75V
and and the open circuit voltage of a 144 cell solar array may exceed 100V, depending on
local conditions and cell specifications. In that case the number of cells in series must be
reduced.
3.4 Cable connection sequence (see figure 4 at the end of this manual)
First: connect the cables to the load, but ensure that all loads are switched off.
Second: connect the battery (this will allow the controller to recognize system voltage).
Third: connect the solar array (when connected with reverse polarity, the controller will heat
up but will not charge the the battery).
The system is now ready for use.
3.5. Configuration of the controller (see figure 1 and 2 at the end of this manual)
If a Bluetooth device or other means of communication is not available, the VE.Direct
communication port (see section 1.9) can be used to configure the load output as follows:
3.6 The load output
The load out output can be configured with Bluetooth or via VE.Direct.
Alternatively, a jumper can be used to to configure the load output as follows:
3.6.1. No jumper: BatteryLife algorithm (see 1.5.)
3.6.2. Jumper between pin 1 and pin 2: conventional
Low voltage load disconnect: 11,1V or 22,2V
Automatic load reconnect: 13,1V or 26,2V
3.6.3. Jumper between pin 2 and pin 3: conventional
Low voltage load disconnect: 11,8V or 23,6V
Automatic load reconnect: 14V or 28V
Note: remove the jumper when using Bluetooth to configure the controller
Some loads with high inrush current can best be connected directly to the battery. If
equipped with a remote on-off input, these loads can be controlled by connecting the load
output of the controller to this remote on-off input. A special interface cable may be needed.
Alternatively, a BatteryProtect may be used to control the load. Please see our website for
specifications.
