Physical Installation
The BPSS controller is rated for outdoor use and is specifically designed to be affixed to a pole or
post up to 2” O.D. (outer diameter) using the included hardware. Use short U-bolt in lower
mounting holes to allow room for battery. A bracket kit accessory package for larger
diameters is also available (see Section 6). A drop-in hasp for a padlock (not included) has
been furnished to secure the cabinet cover.
The BPSS controller is furnished with a pole/post mounted adjustable PV array panel to be
mounted above the BPSS controller cabinet. Please see Section 5 for PV array panel installation
and adjustment information.

Power Controller Characteristics
Securitron's BPSS utilizes a sophisticated power controller which incorporates advanced
technology and series switching, pulse width modulation (PWM) charging. The battery charging
process has been optimized for longer battery life and improved system performance. Many
specifications of the controller are unique. Although the controller is very simple to use, please
take the time to read this manual and become familiar with its functions. This will help to make
full use of the many advantages the controller can provide to the PV system being used.
4.2.2
Controller Safety
SAVE THESE INSTRUCTIONS! - This manual contains important instructions that should be
followed during installation and maintenance of the controller.
WARNING! - Be very careful when working with batteries. Lead acid batteries can generate
explosive gases, and short circuits can draw thousands of amps from the battery. Read and
follow all instructions provided with the battery.
Do not exceed the voltage or current ratings of the controller. Use only with a 12 Volt
battery rated between 5Ah and 20Ah.
DO NOT short circuit the PV array or load while connected to the controller. This will
DAMAGE the controller.
The controller should be protected from direct sunlight. Ensure adequate space for air flow
around the controller.
The negative system conductor should be properly grounded. All grounding and wiring
should comply with local codes.
4.2.3
Controller Wiring
The six (6) system connections to the controller terminals are numbered “1” to “6” on the label
as shown in Figure 1. It is recommended that the connections be made in order from 1
to 6.
1.
Connect the BATTERY first. Use care that bare wires do not touch the metal case of
the controller.
2.
Connect the SOLAR (PV array) next. The green LED indicator will light if sunlight is
present.
3.
Connect the LOAD last. This model includes a low voltage disconnect (LVD). If the red
LED indicator lights, the battery capacity is low and should be charged before completing
the system installation.
