WARNING
SOLAR PANEL
• For installations with lead acid batteries, avoid sparks or flames near the batteries and
always use proper eye protection
• Given sufficient light, solar panels always generate energy even when they are disconnected
• Accidental ‘shorting’ of the terminals or wiring can result in sparks causing personal injury or a
fire hazard
• Do not scratch or bend solar panels
• Do not disassemble the solar panel
• When mounting solar panels at a height adhere to all relevant safety regulations
• Do not walk on modules
• Do not attempt to increase module output by concentrating light on its surface with mirrors
• Be sure to use components (cables, fuses, etc) greater than 25% of solar panel’s maximum
current ratings
• When storing the Solar panel kit do not pack heavy items on top the Solar panel bag
• Do not disassemble the controller. Take to a qualified person if the unit requires repairing
FEATURE OVERVIEW
SOLAR PANEL
Compact and Powerful – Monocrystalline solar panels are manufactured from a solar cell that
is cast from silicon. These cells are more efficient at producing power than an amorphous panels,
so the size of the panel is smaller yet produces greater output power.
Heavy Duty Frame – Corrosion resistant frames are constructed to withstand wind speeds in
excess of 130 km/h in typical ground mounted applications. The frames are black anodized and
the corner connection has a strong mechanical resistance to weather.
Convenient Carry Bag – This durable padded bag protects your solar panel during storage
and transportation.
Carry Handle & Safety Latches – It is easy to carry the solar panels whilst out of the bag with
the carry handle and using the safety latches to keep the solar panels closed shut.
5 Meter Lead with Battery Clamps – 5 meter battery leads are connected to the solar panels
with battery clamps, so all you have to do is connect to the battery.
Fold Away Support Legs – The convenient support legs fold out from the rear to allow
easy mounting on flat ground. The legs place the panels at an optimum angle for maximum
performance.

SPECIFICATIONS
SOLAR CONTROLLER
3 Stage Charging – Built in regulator to prevent your battery from being overcharged.
Overcharging occurs when the charge voltage is unregulated. This can result in premature
battery failure.
The regulator also prevents your battery from being under charged, in the solar energy field,
battery undercharge always occurs, especially on some Conventional lead – acid or Calcium
batteries; The unit provides an automatic Equalization feature for deeply drained Conventional
lead acid batteries or Calcium batteries.
It keeps the battery fully charged by using a process called “floating”. This means the controller
will stop charging when the battery is full and will automatically start charging the battery as
required. This process will also reduce water loss and help prevent the battery from ‘drying out’.
Discharge Protection – Protects your battery from discharge at night. Under low light or no
light conditions the solar panel voltage could be less than the battery voltage. The unit contains
a special circuit which prevents current flowing back from the battery and into the solar panel.
LED Indicators – Coloured LED’s to easily indicate the operational status and battery conditions.
Unit Protection – Multi charging protects against reverse polarity, short circuit, over temperature,
over voltage, etc.

Level 3*
Level 4
Green ON when solar is charging battery
Green blink when the system is over voltage
Green ON when battery level in the right range
Green slowly flashing when battery level full
Yellow ON when battery level low
Red ON when loads cut off
Red slowly flashing when it is over load (the load amps is 1.25 times of rated
current for 60 seconds, or the load amps is 1.5 times of rated current for 5 seconds)
Red fast flashing when the load is short circuited
Red ON when the switch is ON
Red OFF when the switch is OFF
CHARGING STAGES
Bulk Charge (Level 1) – Maximum current charging until batteries rise to Absorption level
Absorption Charge (Level 2) – Constant voltage charging and battery is over 85%.
Equalization Charge* (Level 3) – Only for WET battery or Calcium battery type, when the
battery is deeply drained below 10V, it will automatically run this stage to bring the internal cells
as an equal states and fully complement the loss of capacity.(Gel and AGM battery do not run
Equalization charge)
Float Charge (Level 4) – Battery is fully charged and maintained at a safe level. A fully
charged battery has a voltage of more than 13.6 Volts.

INSTALLATION & CONNECTION
STEP 1 Locate the panel in the best position
Locate the panel in a position where it is exposed to the sun for the majority of the day. For best
results use a northern orientation. The panel will function in the horizontal or hung position,
however for best performance tilt the panels so they directly face the sun.
STEP 2 Connect to the battery
Connect the 5 meter lead to the battery,
Red clamp to the positive (+) terminal and
Black clamp to the negative (-) terminal.
MAINTENANCE
Periodically inspect the electrical and mechanical connections. Make sure they are all tight and
free from corrosion. If necessary clean the surface of the solar panels with a soft damp cloth.
Mild detergent can also be used. Any dirt or residue on the glass may effect performance.

FREQUENTLY ASKED QUESTIONS
Q. Can the solar panel be mounted on a flat roof or wall?
A. Yes. It is fine to mount the panel on a horizontal surface such as a roof or on a vertical surface
like a wall as long as the panel receives full sun for a reasonable period of the day. You will
however gain better performance if the panel is tilted toward the sun and faced in a northerly
direction, since this enables the maximum amount of solar energy to reach the panel.
Q. What current output can I expect?
A. The current output of the solar panel is based mostly on the available solar energy (sun rays).
The current ratings given in the specifications table are based on the ‘ideal’ sunlight conditions.
In reality this may be achieved only on a very bright sunny day. The normal current output will
therefore be a little lower. If the panel is shaded or if it is a very hot day the output will
decrease further.
Q. Will it charge my flat battery & how long will it take?
A. The SPP120K will charge a flat battery (above 9V) 250-1200CCA (Automotive) with a charge
time of 8-35Hrs.
Q. I am going on a 4WD trip, will 120 Watts be enough?
A. It really comes down to how many appliances are drawing power from your battery.
For example:
Most people when they go away would run a Fridge, and a couple of lights to cook with etc.
We need to work out how much power would be used in a day.
Energy consumption per day
If we say we get around 10 hours of solar energy from the panels per day (for summer months).
We can then calculate what size and how many panels we need.
45 amps ÷ 10 hours = 4.5 Amps per hour
So the SPP120K solar panel kit produce 7.5 Amps an hour, this should be more than enough.
You might find that during cloudy weather you will have to charge the battery by running your
car for half an hour every second or third day.
