2 INTRODUCTION
The 110-WS-25SP-50 Solar Panel is suitable for use in challenging environments. The rugged aluminum
frame is attached to a variable-angle bracket that mounts to a mast or tower. A fully-encapsulated
regulator is pre-wired to the panel, providing up to 3 Amps of current at 14.3 Vdc. The 20' (6.1 meter)
cable includes a 2-pin quick-connect plug designed for easy connection to NovaLynx monitoring
systems.
The 110-WS-25SP-50 Solar Panel is optimal for charging 12V sealed lead-acid battery systems. With a
properly-sized battery and adequate sunshine, the panel can supply continuous loads up to 300 mA.

4 INSTALLATION
Select a location that provides maximum exposure to sunlight. In the northern hemisphere, the front
surface of the panel should face south. In the southern hemisphere, the panel should face north.
Shade on even a small portion of the panel surface greatly lowers the efficiency of the panel, so avoid
placing the panel near or under trees, buildings, or any other objects that cast a shadow.
Avoid placing the panel below structures where birds will perch. If birds use the panel itself as a
landing spot, it may be necessary to apply a spike strip along the top edge of the mounting bracket to
keep the panel from being covered with bird droppings.
Regular maintenance includes cleaning the top surface of the panel whenever dust or debris collects.
Place the panel at a height where it is not difficult to reach for regular cleaning.
The 110-WS-25SP-50 Solar Panel mounting bracket is adjustable so that the
optimum angle for a particular latitude can be achieved. The best angle varies
throughout the year, however a good compromise can be reached by
determining your coordinates and entering them into an on-line calculator. One
such calculator can be found at:
https://solarsena.com/solar-panel-tilt-angle-calculator/
Instructions for assembling the mounting bracket are not included in this manual, but may be on a
separate instruction sheet included with your panel.
Assemble the panel and mounting bracket onto a vertical mast or tower (sold separately), and make
sure the face of the panel points south (northern hemisphere). Adjust the tilt angle, then tighten all
bolts. Route the cable to the battery box, and secure the cable to the mast at 2' intervals to prevent
the cable from whipping in the wind.
5 CONNECTION
CAUTION – Connect battery power to the logger BEFORE connecting the solar panel to the system.
Otherwise the logger may not "boot" properly, or excessive voltage may be applied to
the logger system. Do the reverse when powering down, i.e. disconnect the solar panel,
and then unplug the battery to turn off the logger.
CAUTION – The solar panel produces electricity whenever it is exposed to sunlight. There is always
the danger of short-circuiting which could cause sparks or damage to other electrical
equipment if not connected properly. It is advisable to cover the solar panel with an
opaque cloth while connecting the cable.

The 110-WS-25SP-50 Solar Panel cable is provided with a 2-pin quick-connect plug which makes
connection to NovaLynx loggers a simple matter. The plug not only provides insulation which helps
prevent sparks, but also ensures that the polarity is correct for connection to the logger system. If the
quick-connect plug has been removed (i.e. the cable has flying leads), special precautions must be
taken to ensure that the exposed wires do not short together, and that proper polarity is observed.
It is best to "boot" the logger from the battery before connecting the solar panel to the system. In the
case of NovaLynx loggers, this means connect the red battery connector to the positive battery
terminal first. The logger will start up normally and the battery will be in the circuit when the charger
connection is made. Connect the solar panel by plugging the quick-connect plug on the solar panel
cable into the quick-connect plug inside the logger enclosure. After the solar panel is connected,
remove the opaque cloth from the panel. Note: in some systems the battery is in a separate enclosure
from the logger. In this case route the cable from the solar panel to the battery box.
6 OPERATION
The operation of the regulator is completely automatic. No user interface is required after installation.
The controller will regulate the charging of the battery during conditions of heavy usage, or when left
unattended for long periods of time.
The regulator provides pulses of charging current at varying durations to maintain the battery at a full
state of charge and insure the long-term health of the battery. The “on” and “off” cycle time is wide
enough to eliminate electronic noise and short enough to insure the battery is always topped off. This
method allows the batteries to reach a higher voltage with the “on” cycle and protect the batteries
from gassing in the “off” cycle. This will provide the benefits of the higher voltage (reduced sulfation
and stirred up electrolyte) and prevent excessive gassing and excessive water loss.
During a typical day, charging begins with the battery at low capacity. Charging will be continuous. As
the battery charges up, current will pass into the battery for a while and eventually stop. Later,
charging will resume and the system will continue this cycle throughout the day. During the course of
the day, the duration of the charging period of each cycle will get shorter (cycling on for shorter
periods and staying off longer). When the battery is close to full charge, the regulator will pulse current
into the battery to achieve and maintain full charge. This pulse charging is indicated by the
"CHARGING" light occasionally turning on and off.
Please Note: The “CHARGING” light will be on when there is voltage from the solar array and the
battery can use more charging. This could result in the "CHARGING" light being on (bright or faint)
when the panels are in very low light conditions (i.e. night time with moonlight).

8 MAINTENANCE
Under normal conditions very little maintenance is required, but in areas where dust accumulates, the
panel may need to be cleaned frequently. An indicator is whether the battery voltage is maintained in
the best operating range. The regulator switches on when the voltage drops to 13.5 volts, and off at
about 14.3 volts. During the day when there is plenty of sunshine, the battery should remain in this
range.
1. Wash the surface of the solar panel as required using clean water and a soft cloth. Add a mild
liquid detergent to the water to remove heavy soil, if needed, then use clean water to rinse. Do
not use abrasive cleaners which might scratch the glass, reducing efficiency.
2. Tighten the bolts on the mounting bracket to ensure the panel is held securely.
3. Make sure the cable is secured to prevent whipping in the wind.
4. Trim any nearby trees that cast a shadow on the solar panel.
5. Install bird spikes if necessary.
9 TROUBLESHOOTING
Power supply issues usually show up when the battery voltage gets too low for the system to function.
It can be difficult to identify the cause, as there are many parts to the system. Efficient troubleshooting
involves understanding the possible causes and eliminating simplest cases first.
1. If there is a fuse in the system, check the fuse with an ohm-meter. If the fuse is burned out,
determine where the fault lies and correct it before trying a new fuse.
2. Many system failures are due to poor electrical connections.
a. Visually inspect all connections.
b. Tighten screw terminal connections.
c. Where wires are held by crimp connectors, tug gently on the wires to check whether the
connection is tight. Re-crimp as required. NOTE: crimp connections may also be soldered for
maximum durability.
d. Disconnect and re-connect plug-style connectors, to refresh the connection.

TROUBLESHOOTING MATRIX
Low Battery Voltage &
Charging LED off
CAUTION: Use the 10A scale and input jack on the multimeter to check the
short-circuit current.
1. The solar panel may not be working. Disconnect the red wire from the solar
panel junction box. Check the open circuit voltage (18-24 volts) and short-
circuit current (3000 mA in direct sun) between the red wire and the black
wire coming from the junction box.
2. The regulator may not be working. Disconnect the quick-connect plug from
the logger. Check the open circuit voltage (14.3 volts) and short-circuit
current (3000 mA in direct sun).
Low Battery Voltage &
Charging LED on
1. The system may not have had time to re-charge after a prolonged period of
overcast weather.
2. The battery/charging system is not sized correctly for the load requirement.
The 110-WS-25SP-50 Solar Panel connected to an adequately-sized battery
can operate a 300 mA continuous load given good positioning and sunlight.
It may not be adequate where bad weather predominates. Cold weather
can reduce the ability to charge the battery.
Charging LED blinks on
and off
This is normal operation when the battery is fully charged. However, rapid
blinking and/or a buzzing sound can also indicate a poor battery. If the battery
does not maintain its charge overnight, consider exchanging the battery.
Regulator is hot to the
touch
The regulator does get warm during normal operation, but if it is too hot to
touch it may be defective.
