1.0 Introduction
This manual contains important instructions for the TP Series - 3 or 4 panel systems that
shall be followed during installation and maintenance of the charge controller.
The TP Series is a patented, off-grid, standalone, solar-powered lighting system. Years
of engineering, development, and testing ensure that this system meets or exceeds all
performance and reliability specifications. Every system that leaves our factory has been
quality control tested and inspected to assure you of an easy installation and highly
dependable performance. All mechanical fittings and electrical connections are designed
for simple and reliable installation. The system is ready for use immediately after the
components are mounted and the plug and play connectors are joined.
1.1 Operational Principles
The Sol TP Series solar LED lighting system is designed to provide reliable operation and
illumination all year. The solar array (the photovoltaic panel, or PV panels) re-charges the
battery each day, replacing energy that was used during the previous evening so that
illumination can again be provided during the following evening. The system is designed
with a reserve, so that regular illumination will continue to be provided during periods
of rainy or cloudy weather. The controller monitors battery condition and will shut off
illumination if the battery charge drops below a specified level. This may occur if there is
a prolonged rainy or cloudy weather or if the solar array is shaded during part of the day.
The controller automatically restarts the system when the condition is corrected and the
battery charge returns to the specified level, protecting the batteries.
** Battery Enclosure may be
provided with hinged cover
and optional locking device.
1.2 System Overview
Hardware components of the
Sol TP Series lighting systems
are shown in Figure 1.
There are several models
of the Sol TP Series lighting
system.
The models are identical
except for the size of the solar
panel, which is specified for
your location and the fixture
choice.

Installation and Owner’s Manual | TP Series Solar LED Lighting System
2.0 Installation
Install the Sol TP Series lighting system in accordance with all applicable building codes.
Though designed for ease of installation, it is recommended that the Sol TP Series lighting
system be installed by a licensed electrician.
The Sol TP Series lighting system is manufactured to comply with Article 690
of the National Electric Code. Please consult with your local building authority
for requirements that are specific to your area.
2.1 Site Selection and Preparation
Locate and
install the PV
panels in an area where
they can face the
equator (due south
in the Northern
hemisphere) and will
not be shaded by trees,
poles, buildings, or
other objects during the
day (Figure 2).
Installing in a location
where the solar
panels are shaded
during part of the
day will prevent the
solar panel from fully
charging the battery, reducing the hours of nighttime illumination and possibly damaging
the battery.
Before installing near a tree, 1) verify that the municipality allows tree trimming and,
2) understand that the tree branches will likely need to be trimmed on a regular basis.
Do not locate in an area where there is excessive ambient or reflected light at night which
may simulate daylight and cause the system controller to turn off the system.

Installation and Owner’s Manual | TP Series Solar LED Lighting System
3.0 Operation and Maintenance
3.1 Break-in Period
After the TP Series lighting system is installed, the battery, LED fixture, and controller
require a break-in period before reaching peak performance and efficiency:
1. New batteries achieve full charging capacity after they have been used for
approximately 45 days. Before that, they achieve approximately 85% of their
rated charging capacity.
2. The LED fixture must operate for several days before it reaches its peak output.
This will not be noticeable.
3. The controller must operate for approximately one week before learning the
system’s parameters and achieving maximum efficiency.
4. The system may need a full day of peak sun to reset all of its circuits. If the
system is installed during a period of inclement weather or late in the day, the
system may not operate the first night.
The break-in period will not affect normal performance of the light unless the break-in
period occurs at a time that the system is operating at its extreme limits. This may be the
case if the system is installed during the winter months or during a period of successive
bad weather days.
3.2 Expected Performance
The TP Series lighting system is designed to provide reliable operation and illumination all
year. The solar panel provides enough energy during a normal day to charge the battery
for operation of the LED fixture for the following night. The system is designed with a five-
day reserve charge. As a result, extended periods of low sun may deplete the five-day
reserve and affect performance of the system. The following conditions may cause your
TP Series lighting system to operate out of specification:
1. Prolonged Bad Weather. A series of days with low levels of sunlight may
deplete the battery reserve. Depending on the severity of the condition, the
nightly illumination period could be reduced until a sunny day re-establishes the
reserve battery charge. Please note that the system may need anywhere from
two days (in summer) to ten days (in winter) of good sunny weather before the
full five-day battery reserve is completely achieved.
2. Shading. Installation of the TP Series lighting system in a location where the
solar panel is shaded during part of the day will inhibit the ability of the solar
panel to fully charge the battery and may severely damage the battery. The
hours of nighttime illumination will be reduced by the controller if the solar panel
cannot fully charge the battery.
If you believe that your TP Series lighting system is not performing as expected and the
above conditions do not apply, please contact Sol Customer Service at 1.772.286.9461.

Frequently-Asked Questions
Q: Does aiSUN™ or EternO® 4 have a timeclock inside?
A: No, aiSUN™ and EternO® 4 do not have a “timeclocks”, instead they use sun rise and sun set they
detect to determine when night is occurring and for how long. By averaging 10 nights of sunrise and
sunset data the CPU accurately determines length of night and when sunrise and sunset occur.
Q: What happens during daylight savings time?
A: Since aiSUN™ and EternO® 4 perform all of their timing based on sunrise and sunset, daylight
savings time has no impact on the CPU. Daylight savings time is a clock change to accommodate
having daylight hours align with certain times of the day, despite what the clock says, when the sun set
controller turns on the solar light.
Q: Can the aiSUN™ or EternO® 4 be reprogrammed to work a different way?
A: While it is possible to have aiSUN™ or EternO® 4 reprogrammed, it is important to consult with
Sol Inc about what operating modes are available. Solar lights can sometimes run longer or brighter,
however this typically requires a larger solar panel and more battery reserve to provide more light,
longer. These types of changes are costly but are possible.
