The SBP-1100e has two domed buttons for user interaction in addition to to the non-domed ‘RESET’ button. The but-
tons are tactile-feedback membrane switches that give the user a positive indication by feel that the button has been
activated.
The ‘SCROLL’ button allows the user to scroll though a number of options presented on the display. Pressing the
‘SCROLL’ button once will turn on the LCD status display (and backlight) for about 8 seconds. Repeatedly pressing the
button (slowly), will cycle through the display options.
The SELECT button enables a display of product identification information, including the software version number. In fu-
ture versions of the SBP-1100e, the ‘SELECT’ button will implement a menu system. Pressing the ‘SELECT’ button once
will turn on the LCD status display (and backlight) for about eight seconds, and display:
SBP-1100 V4.1.2

Repeatedly pressing the ‘SELECT’ button (slowly) does the same.
LCD Backlighting
The LCD on the top of the SBP-1100e has backlighting which makes the display readable in the dark. The backlighting
turns on automatically whenever one of the buttons on the control panel is pressed. The backlighting will remain on for
about 8 seconds and then automatically turn off to save power, unless a button is pressed again before the backlight
has turned off, in which case the backlight will remain on for eight seconds after the last button press.
LCD panel indications
The LCD panel on the top face of the SBP-1100e indicates the status of the unit, in response to pressing the ‘SCROLL’
button. There is space for two lines of text or graphics on the display, and when the ‘SCROLL’ button is pressed, the top
line will display the present charge state in two formats: the numerical percentage and a horizontal bar graph. The per-
centage indicated is the relative state of charge between 0% (fully discharged) and 100% (fully charged).
The bar graph indication uses darkened blocks to represent full increments of 10% charge capacity. In the example
below, the unit shows that it has 78% of full capacity left and the bar graph shows 7 blocks.

The second line of the LCD is used to display other operating parameters for the SBP-1100e, including the status of
charging or discharging, output voltage and current, and input voltage and current. The charging or discharging status
includes an estimate of the amount of time remaining for the unit to reach the end state of fully charged, in the case of
charging, or discharged to the point of output cut-off in the case of discharging, assuming that charging or discharging
continues at the present rate.
When the SCROLL button is pressed while the display is blank, the backlight turns on and the state of charge appears
on the top line of the display, while the second line will show one of the following typical display formats:
Charging 4.5HR
Dschging 3.0HR
Idle
Twilight mode
In 23.5V 3.2A
Out 13.8V 4.3A
In Temptr +27C
Out 43C
Press the ‘SCROLL’ button (slowly) to cycle the LCD display through the series of screens which show input and output
voltages and currents, and other informational displays including the temperatures of the input and output power con-
version modules inside the SBP-1100e.
At any given time, the SBP-1100e will be in one of several operating modes including: Charging, Discharging, Idle, Twi-
