If the B- input is not being used for this, then it
can be used for sensing the voltage on a second
battery being charged or for providing a voltage
input for the event controller (VEXT).
Some inverter-chargers, such as the SP PRO,
can communicate to the charge controller when
they want to export power to the grid. Selecting
BSET=3 enables this.
‘Push Button’ Switch Input
To use the B- sense input as a switch event input,
wire a switch (or other voltage free contact
closure device) between the B- terminal (green
terminal block) and the Bat- terminal (and set
BSET = 2). See Figure 7.5.3B
This is an example of using a push button
switch to turn on a light - see section 7.6 Event
controller example 2 for setting details.
